Red-bellied Woodpecker
can use its bill to obtain insects from just below the bark surface, employing
an action like a pickax, to obtain invertebrates that bore into wood and are out
of reach of other birds. What many people don't realize, however, is that
they often use their bills in more subtle ways first, tapping to detect where
bark in worn and where there may be hollow chambers inside.
Throughout the year the hard, heavy tapping is used to make cavities for nesting
and roosting. It can take up to 3 weeks to create a single hole. The
tapping is also put to good use to advertise for and attract a mate. The
so-called "drumming" is not, as many people think, the sound of excavation of a
hole, but it is actually the knocking of the bill against a suitably sonorous
piece of wood simply to make a signature noise. (Extreme
Birds: The world's most extraordinary and bizarre birds, 2008,
Dominic Couzens)

The species account in Birds
of North America Online says
the pair bond lasts about seven months, through the nesting season, and it is
"rare to find mated pairs from September through January." It mentions that both
sexes excavate cavities for roosting, and both sexes change roost sites
frequently, but says "adults roost singly in cavities at night," and does not
describe pairs working together on roost holes. Clifford E. Shackelford, Raymond
E. Brown and Richard N. Conner. 2000. Red-bellied Woodpecker (Melanerpes
carollinus), The Birds of North America Online (A.

There are numerous winter records of the hermit thrush in southern New
England, where it has been reported in favorable situations throughout
Massachusetts and Connecticut even at times when it was very cold and the ground
covered with snow. It has also been reported from various sections of New York
and New Jersey during the winter months. South of this area it is a regular
winter resident.

Hooded Mergansers still here, many males courting a female with display; I
encountered them in closer distance than before. So do
Shovelers. I saw 1 male going after a couple and another male is in a not
so far distance. I think these 2 are not their sons but males failed to
form pairs.
The couple tends to do sieving together and the other 2 males form
another team.
Got a lot good pictures and videos of both species. What a Christmas
banquet of ducks!

After the p.m. walk, we went grocery
shopping. Before leaving the Chinese supermarket at about 4 p.m., we saw a
Nissan van with a broken right-sided back-seated window. The African
American lady called the police and mentioned that she just left the van for
about 10 minutes in the parking lot. That means within a short period of
time, her stuff become someone's Christmas gift. This is really a crazy
holiday. Be alert while doing Christmas shopping.

Note: 10/30 (Sun) morning after the first snow this year yesterday saw a female Ruby-crowned Kinglet (or warbler) with wing bar & whitish yellow
belly at the (probably an evergreen coniferous 針葉) shrub (or bush 灌木) behind the "water foundation garden." Robin. 10/23 (Sun) morning & afternoon am: Cloudy in the early morning so bad for photographing. White-throated Sparrows.
A survey of 40 species of 14 genera of North American wood-warblers (Parulidae)
reveals that the head-scratching method employed is surprisingly stable
within species. The experiments by Nice & Schantz (1959a, b) induced some
normally overwing head-scratchers to scratch the head under the wing. It is
suggested that this was because their leg rings became caught in secondaries,
making normal overwing head-scratching impossible. A few exceptional
head-scratching patterns under different conditions invariably involved
normally overwing head-scratchers employing the underwing method, and a few
species head-scratch under the wing as nestlings but change to overwing
before fledging. In all, 31 species appear to be normally overwing
head-scratchers, seven are underwing head-scratchers, one species uses both
methods and one remains uncertain. There is no evidence for lateral
preference in either head-scratching method, and head-scratching is only
loosely linked sequentially to preening. The functional significance of
head-scratching may be related to blockage of the eustachian tube, or to
cleaning and oiling the feathers. Avian head-scratching is more difficult to
homologize with mammalian head-scratching than others have considered it to
be, but all evidence suggests that within birds underwing head-scratching is
phylogenetically primitive. In wood-warblers, the head-scratching method
does not correlate with taxonomy. However, ground-dwelling wood-warblers
tend to scratch the head under the wing and arboreal wood-warblers over the
wing. This correlation provides the first strong clue to the functional
significance of the difference between methods in passerine birds. 10/22 (Sat) morning & after dim sum Nice weather for walking & photographing. Immature Indigo Buntings, Hermit Thrush, Waxwing & Robins. Ruby-crowned Kinglets, White-throated Sparrows. There are many different lineages of cuckoo
bees, all of which lay their eggs in the nest cells of other bees.
There is also a family of cuckoo
wasps, many of which lay their eggs in the nests of potter and mud
dauber wasps; many other lineages of wasps
in various families have evolved similar habits. These insects are normally
referred to as "kleptoparasites," rather than as "brood
parasites." The distinction is that the term "brood parasite" is generally
restricted to cases where the immature parasite is fed directly by the adult of
the host, and raised as the host's offspring (as is common in birds).
Such cases are virtually unknown in bees and wasps, which tend to provide all of
the food for the larva before the egg is laid; in only a few exceptional cases
(such as parasitic ["cuckoo"] bumblebees)
will a bee or wasp female feed a larva that is not her own species. The
difference is only in the nature of the interaction by which the transfer of
resources occurs (tricking a host into handing over food rather than stealing it
by force or stealth), which is why brood parasitism is considered a special form
of kleptoparasitism.
Parasitism / Parasitoidy / Predation
In practice it is not always necessary to distinguish parasitoidy from
parasitism, nor is it always even possible to do so cleanly. However, when it is
appropriate to do so, a typically parasitic relationship is one in which
parasite and host interact without lethal harm to the host, and without
dramatically reducing the host's reproductive
success.
In most such relationships, the parasite arrogates enough nutrients or
other resources to
thrive without preventing the host from reproducing. In contrast, in a parasitoidal relationship
the exploiting organism kills or sterilises the
host, typically before it can produce offspring. A non-lethal parasite sometimes
is termed a biotroph.
In contrast, when a parasitoidal relationship is regarded as a form of parasitism,
the parasitoid may be called a necrotroph. [A]t
the opposite extreme from parasitism, parasitoidy in turn grades into predation.
Differences between various kinds of hunting wasps provide convenient
illustrations. Predatory social
wasps hunt
flies, caterpillars and the like, grab them, butcher them, carry them home and
feed them to their young. That is patent predation. Some solitary
wasps,
such as bee pirates, sting prey, sometimes fatally, before saving it, usually
entire, in a nest or burrow for the young to feed on. That too is predation,
fairly clearly. 10/15 (Sat) 12-3pm 10/10 (Mon) 11:30am-3:30pm
(3) Big John's is a vernal pond, which means it dries up in late summer. It
cannot support animals that need a body of water year-round, but is just the
thing for: 10/8 (Sat) 11am-12:30pm Overwinter as adults. Emerge in mid-spring, mate, and lay eggs. In the spring adults and nymphs will feed on seeds and maple trees. This first generation of nymphs may feed on dead insects including their siblings. These nymphs will emerge as adults in early summer. In the summer and fall, the adults and nymphs will suck sap from new tree (usually boxelder) growth and may feed on weeds and other plants. This type of plant feeding is usually non-damaging but when they feed on strawberries it can be very damaging. The second generation will occur in late summer and will have adult emergence in October. This generation is the one that will overwinter after the first frost.

The Eastern Boxelder Bug is sometimes known as a garage beetle or may be confused with
other Jadera spp.,
especially Western Boxelder Bug ( Boisea
rubrolineata ). The name "stink bug (放屁虫),"
which is more regularly applied to the family Pentatomidae,
is sometimes used to refer to Boisea
trivittata. Instead, these insects belong to the family Rhopalidae,
the so-called "scentless plant bugs". However, boxelder bugs are redolent and
will release a pungent and bad-tasting compound upon being disturbed to
discourage predation; this allows them to form conspicuous aggregations without
being preyed on.
Golden rain tree bug
(Jadera) is sometimes confused with the boxelder bug.
Jadera haemotoloma is closely
related species that is occasionally mistaken for
the boxelder bug, but lacks the red lines on wing edges. And the
small milkweed bug & large milkweed bug are seed feeding bugs that
resemble the boxelder. Small
Milkweed Bugs and Large Milkweed
Bugs have a different pattern of red/orange markings.
Neacoryphus lateralis (or
Melacoryphus lateralis) has similar coloration, but red markings are
somewhat different - red stripe at neck but no red edges to wing covers.

Met photographer Johann Schumacher again at Big John's Pond. Photo: 9/25 (Sun) 11am-2pm Nice pictures of Monarch & flower flies. Consistently good at shooting
Monarch butterflies but bad at damselflies. Why? Is this pattern
telling something? Camera is easier to focus on the contrasting pattern on
Monarch but not on the thin and far away body of damselflies. Focusing on
Cabbage Whites is also so-so. Try increase

Key to California dragonflies/damselflies A review on 100-300mm says: ... its sharp, very sharp if you nail the focus which is
actually not easy at times, especially when handholding a shot. When you are dealing with focal lengths that long, the
increased M4/3 DOF is no longer very noticeable and shooting wide open, you have
to be bang on with your focus or you’ll see that it’s out. It has the same O.I.S
twitchiness as the 45-200, only worse because of its increased magnification. If
you are going to shoot handheld at any shutter speeds below 1/1000,
you’d better give the
lens a moment for its stabilizer to lock on before squeezing off a shot.
This lens really demands a tripod, but since it is still so lightweight, there
is no tripod ring needed.
With regards to using these longer lenses wide open and trying to achieve a
precise point of focus, I’ll mention that the GH2 body can sometimes be
frustrating in its seeming insistence in focusing on things that are clearly
outside of the displayed AF rectangle in the viewfinder. This is very “DSLR
like” in some respects and unnecessary since there is no reason why the AF
rectangle couldn’t exactly match the actual focus area that is used. More on
auto-focus performance, and some of its quirks, especially with long lenses, in
my upcoming GH2 body review, which will appear in a new blog entry as “Part 2”
of my Panasonic review.

southern and mid-western. Periodic cicadas generally emerge
in May and June, apparently when the soil temperature reaches 64°

The Hooded Merganser finds its prey underwater by sight. The merganser can
actually change the refractive properties of its eyes to enhance its underwater
vision. In addition, the nictitating membrane (third eyelid) is very transparent
and probably acts to protect the eye during swimming, just like a pair of
goggles.

(2)
Hooded Mergansers are not considered to be the most graceful while on
land, but they are quick flyers. They take off by
running on top of the water, and with wings flapping continuously until they are
airborne. While in the air, they are extremely fast and agile flyers weaving
through their forest habitat until reaching their destination. They also land
fast onto the water, skiing across it until they stop. The Hooded Merganser are
not only agile in the in the air, but exceptional divers and swimmers. When
diving, they fold their wings close to the body and use their feet to propel
them through the water. src
(3) During the breeding season, breeding
males display a wide variety of ways to attract
potential mates. The Hooded Merganser is extremely vocal letting out a frog-like
croak, which can be heard a half mile away. They may also display their crest,
which will invite the receptive female to mating with them. A head-throw, is a
common display during courtship. During a head-throw a drake will swim parallel
to a female with his crest fully erected as he passes the female, he throws his
head back quickly until it reaches his back. Then, he slowly raises his head
forward while letting out his frog-like voice. The female responds by either
ignoring his postures or accepting it by bobbing and pumping her head. The
female may also display her receptiveness by stretching her neck and head just
above the water and flattening her tail on the waters surface.
src
(4) Most ducks
confine their displays to the water (or land) surface, since their heavy weight
relative to their wing area ("high wing loading") dictates continuous flapping
and makes complex maneuvers, such as hovering and soaring, difficult or
impossible.

(5) Ring-billed gulls begin breeding at
3-4 years of age.

Northern Shoveler swirling pair
YouTube 720p
Double-crested Cormorant
(1) Northern Shovelers feed by
dabbling for plant food, often by swinging its bill from side to side and using
the bill to strain food from the water. They use their highly specialized bill
(from which their name is derived) to forage for aquatic invertebrates - a
carnivorous diet. Their wide-flat bill is equipped with well-developed lamellae
- small, comb-like structures on the edge of the bill that act like sieves,
allowing the birds to skim crustaceans and plankton from the water's surface.
This adaptation, more specialized in shovelers, gives them an advantage over
other puddle ducks, with which they do not have to compete for food resources
during most of the year.

(3) The unique bill morphology
of Northern Shovelers allows this species to exhibit one of the most unusual
feeding behaviors of any duck. Its large spoon shaped bill is adapted for
sifting large amounts of muddy water. Their tongues are highly specialized with
extensive comb-like teeth called lamellae, which help filter food items from the
water. Moving its head side to side, water is drawn in at the tip of the bill,
filtered through the lamellae to pick up any food particulate and then expelled
at the base. The breeding season for
Northern Shovelers begins on the wintering grounds in December, where courtship
of hens by a group of drakes commences. By January, the majority of individuals
have paired before they start their spring migration and most return to the same
breeding grounds they used the previous year.

(4) Shovelers are specialized for the
time-consuming process of sieving plankton from the waters
of small, permanent ponds. A male defends a small, discrete territory around his
mate, with whom he has a strong, long-lasting relationship; consequently he
rarely spends time in "extramarital" pursuits. Unlike relatively sedentary
shovelers, pintails (again, a member of the genus Anas) range far and
wide to forage in temporary bodies of water, and tend to nest in sparse cover at
a great distance from water. In addition, male pintails spend only part of their
time with their mates, and devote some of their time trying to copulate with
other females; as a result female pintails tend to be frequently harassed. It
seems likely that close defense of a territory is profitable for the male
shoveler because concentrated food resources allow him to provide an area where
his mate can obtain sufficient food free from harassment. No such strategy is
feasible for the male pintail because of the dispersed nature of that species'
food resources. Therefore Northern Pintails and their relatives (e.g.,
Green-winged Teal) have not evolved a conspicuous long-range territorial threat
display; they need only guard nests and mates, not feeding territories.

Notes:
(1) After the breeding season, Common Grackles form large foraging flocks that
often include other blackbirds and cowbirds. Flock size increases as birds from
the northern part of the range migrate to winter destinations in the
southeastern United States, from the Carolinas to the Gulf Coast. In flight, the
flocks tend to be as broad as they are long, unlike the long and cylindrical
flocks of Red-winged Blackbirds.
src
(2)
Q: I saw a large flock of grackles heading directly east on August 10.
Were they starting their fall migration? I also saw large flocks of
starlings in August. Does that early migration mean that we will have a cold
winter?
A: As for the flocks of grackles moving in a given direction in early
August, that was not migration. Grackles never start their migration until late
October. Each species migrates at the same time every year to within a week. The
timing is governed by their hormones which in turn are stimulated by the
shortening of the daylight hours in the fall. The date they start to migrate is
not due to a lack of food, nor to some sense that the winter will be severe. It
depends on the sun and that does not change. It is quite normal for starlings
and grackles to gather into flocks after the nesting season is over. Each
species gathers into its own flock to forage for food and especially to roost
together with their own kind at night.
src
(3) The name green bottle fly (or greenbottle fly) is applied to numerous
species of blowfly, in the
genera Lucilia
and Phaenicia (the
latter is sometimes considered a subgenus of the former). The maggots
(蠅蛆) of this fly are known to preferentially consume dead tissue while
leaving live tissue intact, and so have been sold for use in maggot therapy.
Forensic importance: These flies are known to lay eggs in cadaver tissue
(屍體組織) in the wild within hours
after death. The developmental stage of their larvae in the cadaver can be used
to accurately predict the time death occurred.

Representative Species:
The bluebottle flies (Calliphora vicina and
Calliphora vomitoria),
measure 1/4 to 9/16 inch long and have a dull bluish-black thorax and a
shiny metallic dark blue abdomen.
Many guide books on insects show pictures of Bluebottle Blowflies that are actually not
Calliphora vicina, but rather Calliphora vomitoria. However
C. vomitoria is a very rare species. Usually the Bluebottle
Blowflies commonly found in gardens and sometimes indoors is C. vicina.

yellow-orange jowls with black hair; C.
vomitoria:
black jowls with predominantly reddish hair. Note: jowl:
The lower part of a person's or animal's cheek, esp. when it is fleshy

The bronzebottle fly, Phaenicia pallescens (formerly
Phaenicia cuprina), are 3/16 to 3/8 inch long with a shiny thorax and
abdomen that are colored metallic bronze.
The greenbottle flies (Lucilia illustris and Phaenicia
sericata), range about 1/4 to 3/8 inch long and have a shiny metallic
green thorax and abdomen without stripes.

Reversing at 42mm gives magnification greater than Raynox 250 on 100mm.
Despite of MF, I get some pretty sharp pictures, to my eye its sharpness is like using
Raynox on 100mm with 1-area-AF. Reversing at less than 42mm is more likely
to give less
desirable results because of the shallow DOF caused by greater magnification.
But it still causes quite dramatic vignetting. Try Nikon 5T (1.5 diopters,
thread/size is 62mm) which somebody got excellent results (src).
I think the size of Raynox is only 43mm so using on 67mm lens will
cause vignetting. (not necessary, I got quite good
result @ 100mm using
23-area AF on 10/23). Nikon 5T will be better. But the best result is
Nikon 5T on 14-140mm lens. Canon 500D (2 diopters) has 72mm thread so I
can use 67-72 step-up ring to mount it. Note: for the 14-140 with the 5T
mounted, the distance to subject focal length is around 36" to 18" you can still
AF easily...where the 100-300 and 45-200 with Panasonic
DMW-LC55 (thread is 55mm) or Canon 500D are limited to 12-24". So
the best for low-level magnification (2 diopters or less) is 14-140 + 5T.
And But Nikon 5T is cheaper even more expensive in
eBay since not produce anymore.
New Canon 500D is quite
expensive. Buying
Panasonic Elmarit Leica DG Macro - 45mm f/2.8 instead of a new Canon 500D
72mm ($300 as of 10/31/2011) or an used for $100.
The
diopter of 100-300mm lens + 5T = 1/1.5m + 1.5 (diopter) = 2.167 ;
the new focus distance - 1/2.167 = 0.46m, pretty good. For
Canon 500D is even shorter (0.375m or 1.2'). And above say AF will work at
12-24" on 14-140mm so I expect similarly on 100-300mm (perhaps 15-30"?).
So Canon 500D 72mm will be a great macro lens for 100-300mm, esp. shooting at
300mm with a distance (2-3 feet).
Canon Close-Up Lens 500D is a double-element accessory that attaches to
front of lens. It changes closest focusing distance from infinity to 500mm
(approx. 19.7" from front of lens).
A working setup with Olympus RF-11 Ring Flash
(expensive
and don't forget an external Panasonic-compatible flash unit is need)
is:

ebay - new for $25 + free shipping
67-72mm Step Ring
Canon 500D 72mm Close Up Lens
Since the RF11 doesn't allow room to screw the 500D on, you have to
install kiwi adapter to allow the 500D to be installed...a larger setup but
works a charm...
Raynox 250 will be still useful for 14-42mm lens & FZ35 (with 46-43
step-down adapter).
Step-up ring can be used to prevent vignetting. Sometimes a filter can
produce vignetting, especially on wide angle lenses. Stacking filters may cause
vignetting as well. If using the adapter ring with larger sized filters, the
problem may be eliminated as the filter rings are expanded out beyond the lens.
In my case, 43mm Raynox on 67mm 100-300mm causes vignetting. But using
67-72 step-up ring with 72mm Canon 500D will prevent this kind of vignetting.
around home
Huge swaths of the north-eastern United States have been hit by a rare October snow storm that struck across the region from Virginia all the way to Maine.
Dubbed "Snowtober" by news organizations covering the unusually early winter storm, the massive weather formation dumped up to 30cm (one foot) of snow in parts of the country that rarely see it this early in the year.
...
In a few parts of the country the storm was an almost once-in-a-lifetime event. New
York City has seen measurable October snow just three times since 1869, when
America was still recovering from the civil war. But 2011 has been an unusual
year for New York weather, as the city was also directly hit by Hurricane
Irene just a few months ago. Over New York and other areas the storm was
also accompanied by thunder and lightning, another fairly rare event known as "thundersnow".
src
An unprecedented (for October) 2.9 inches of snow was measured in New
York City's Central Park on Saturday. Since snowfall records began in 1869,
Central Park has never received an inch of snow on any given October day. The
last time that Central Park recorded measurable snow was on Oct. 21, 1952 when
0.5 of an inch fell. Prior to that, 0.8 of an inch fell on Oct. 30, 1925.

Bald-faced Hornet - also commonly called

http://bugguide.net/node/view/33230
Wasps can be divided by their habits into social and
solitary types. Social types are the familiar yellow jackets, paper wasps and hornets, which
live in colonies or communal nests, may sting severely and often appear very
numerous. ... A far greater number of species of wasps are solitary types, in
which each individual leads an independent life.
Apart from a few exceptions,
solitary wasps are hunters. The females hunt other insects and store them
in burrows or hollow mud cells. This is not to provide food for
themselves, but as a store for their larvae. The exceptions are the
solitary wasps that have a parasitic or "cuckoo" mode of breeding
("kleptoparasites").
So solitary wasps = hunting (predatory) wasps (mainly) + wasps being
kleptoparasites (exception).
Question:
giant ichneumon wasp is
predatory wasp or not?
I think is not
"cuckoo"; is predatory although is parasitoid - "most [Ichneumon wasps] are parasitoids—the larvae feeding
on or in another insect which finally dies."
wiki
Definitions and distinctions of Parasitoidy from Parasitism
Potter wasps (or mason
wasps)
are a cosmopolitan wasp group
presently treated as a subfamily of Vespidae,
but sometimes recognized in the past as a separate family, Eumenidae.
... All known eumenine species are predators, most of them solitary mass
provisioners, though some isolated species show primitive states of social behaviour and progressive
provisioning. So I think solitary hunting wasps are mostly mass
provisioning while social wasps are progressive provisioning. Info:

beetles (Coleoptera); and moths (Lepidoptera). b) vertebrates that feed on
wasps: numerous species of birds, skunks, bears, badgers, bats, weasels,
wolverines, rats, mice and last, but certainly not least, humans and probably
some of our closest ancestors.

Bald-faced Hornet (Dolichovespula maculata) -
Bald-faced Hornets are predators and they attack only live prey. They are mostly
predators of spiders, harvestmen, hemipterans, spittle bugs, house flies,
sawflies larvae, caterpillars, beetles, other yellowjackets
species and grasshoppers. The adults carry their prey or part of them to
the nest to feed their larval states. They sometimes feed of flower nectar or
sweet substances (Akre et al. 1981, VanDyk 2003).

The most visible physical difference (at a glance) between
Eastern carpenter bee
and a bumblebee is
the abdomen.
Eastern carpenter bees have a shiny black abdomen, with the only yellow hair
present being at the base next to the thorax, while bumblebees have a very fuzzy
abdomen, which in some species has large areas of yellow hair across the middle
(this is visible and obvious). The female eastern carpenter bee also has a much
broader head than bumblebees. Eastern carpenter bees can be sexed at a glance.
Males have a patch of white cuticle on the face, as opposed to females, whose
faces are black. Males are unable to sting, since a bee's stinger is a modified ovipositor (an
egg laying organ).

3. Common Buckeye (Junonia coenia, described by Jacob Hübner in
1822)
(= Precis coenia) -
Males perch during the day on low plants or bare ground to watch for females,
flying periodically to patrol or to chase other flying insects. Flight: Two
to three broods from May-October. Passing through New York,
heading south (so will see it in September). Their southbound autumn
flight is particularly noticeable along the coasts where at times they seem to
be everywhere. Every spring some of them return to repopulate the northern
United States and parts of Canada. Buckeye butterflies appear in different
forms in different seasons. Underside of hindwing is brown or tan in the
wet season (spring/summer) form and rose-red in the dry season (autumn) form.
The change is probably linked to lower
temperatures and shorter days. The difference is so pronounced that scientists
call the forms by different names -- linea for the tan one and rosa
for the other.

6. Green Heron is the best fly fisher (cunning & patient) :
Adopting an almost horizontal posture, a green
heron prepares to lunge toward a fish beneath a lily pad. Within seconds
it will make a grab -- aided by a special arrangement of the vertebrae that
enables the neck to "snap" forward -- and will soon have the fish wriggling in
its jaws.
All over the world, other species of heron
practice the same technique, and at first sight there seems nothing unusual
about what this green heron is doing. There is, however, a very big
difference. In many ways the green heron has more in common with a human
angler than any other species. It regularly uses bait to lure the fish
within its reach. Using tools is a rarity among birds, but the green
heron, along with several very close relatives in other parts of the world, is
known to place a variety of different objects into the water in front of it then
lunge at fish attracted to the lures.
Green herons have recorded using sticks,
feathers, bread, captured insects, flowers and corn. All of which have
been picked up from the edge of water and dumped onto the surface.
American birds have been seen to use popcorn. Clearly some of these are
edible items, but feathers and sticks act as "dry flies" of no nutritional value
that are sufficient to fool a fish. Interestingly, some green herons snap
twigs off waterside vegetation to produce their bait, a rare example not just of
using tools but of making tools, too.

Sanderling feeds on various items close to the water's
edge. It probes and pecks rapidly, following the waves’ movements. This bird is
able to locate the prey thanks to its smell, touch and taste.
It quickly probes into the sand, repeatedly,
while walking or running on the beach. It feeds in small groups of 5 to 20
birds, but also in large flocks. It may feed by day and by night.

I just spoke with Jeff Nulle and he wanted to let you know that the Riverside
Park (Manhattan) Bird Drip has been turned back on today.
This is from Phil Jeffrey's "Birding Wiki" on Riverside Park:
http://www.nycbirds.com/wiki/index.php?title=Riverside_Park (more on
NYC Birding
Wiki)
"The Drip" is an area under some rocks where water is piped in. Birds like to
drink and bathe in it. Many others hang around in the trees and bushes near by.
It is great because it allows for good and fairly close views of warblers at
ground and eye level - not just high up in the trees.
The closest entrance to the Drip is at 120th Street across from Riverside
Church. Go down the stairs at the "Forever Wild" sign, turn right and go down
those stairs. The tennis court will be on your right. Turn left and walk toward
the fenced-in area which will be on your left.

blue tip (segments 8 and 9) and thin pale tings; black spots on sides of blue
tip. Eyes dark above, greenish below, with small green eyespots.
What I saw at Kissena Park behaved like Emerald Spreadwing: (1) weak/slow flight
and brief; (2) wings held partially spread when perched.
Or a hybrid female Mallard X American Black Duck because it has a dull greenish
gray bill (like female American Black Duck)
with little marking (like male American Black Duck).
Or immature Mallard or American Black Duck.

- "In August, the juvenile goes through a preformative molt ... head is still in
juvenile plumage. ... By November, the Starling has completed its
preformative molt and has attained its formative plumage. ... By late summer,
the now one-year-old bird is beginning to grow new feathers which push out the
old, worn feathers. This is the second prebasic molt (the first prebasic
molt having taken place in the nest)."
Usually, starlings molt their feathers in the fall.

Andromorph (male-like) form vs. heteromorph (female-like) form.
Google : "female polymorphism".
As in butterflies, where this type of polymorphism also occurs
(Clarke
et al., 1985), one of the female morphs is very similar to the
conspecific male, whereas the other phenotypes differ in coloration. The
different morphs have been given various names in the scientific literature.
Because the differences among morphs involve their colour only and not their
morphology, this paper will use the terminology proposed by
Hilton (1987) and shortened by
Cordero et al. (1998), using 'androchrome' for male-like females and
'gynochrome' for those females with a different coloration.

The three of us, joined by Bob Kurtz, then worked the south end and up the
east side of the East Pond. If you understand that you're going to get wet,
you can make it a good distance past the raunt. A problem not always
mentioned is that with little shoreline, you can't avoid disturbing all the
birds along the way. Be that as it may, we eventually found both HUDSONIAN
GODWITS and 1 MARBLED GODWIT spending their morning on the west side of the
pond, a good distance north of the raunt. No White Ibis to be seen. Both
Marbled Godwits were later found at low tide on the bay, north of the dike.

Not sure, not seen or not pay attention: Crow, Grackle, House Sparrow, Yellow Warbler, Least Tern?, Cardinal?,
The 2 juvenile ospreys stay at the nest while the other one (probably is the eldest one who fledged already) and parents are not there. When will these 2 young one spread their wings?
I saw the shorebird digging in sand so probably it is a Ruddy Turnstone (legs and feet are orange). Least Sandpiper has yellowish or greenish legs. Semipalmated Sandpiper has blackish legs. Probably not White-rumped Sandpiper. I can't see clearly the leg color nor white rump or not.

There are 6 species of "Black" Swallowtails
resident in the lower 48 states: Anise, Black, Indra, Old World, Ozark, and
Short-tailed swallowtails. In the East, flight of Black Swallowtails is
throughout the warmer months. In the West, Anise Swallowtail flies mainly
May-July, longer along the coast. Other species are less common.

Osprey: 小魚鷹試飛成功

Large swaths of oyster reef once lined the bottom
of the Hudson-Raritan Estuary (河口),
cleaning the water and providing
a source of food. Overfishing through the
19th century, the release of untreated sewage
into waterways, and other ecological disturbances
have virtually eliminated the habitat of
this keystone species. Today there are no major
naturally occurring oyster reefs in the region,
though scattered oysters remain. "Oysterculture"
has been gaining momentum in recent
years as evidence suggests that oysters aid in
the restoration of bottom-sea habitat and the
filtering of the water column.
Many small-scale restoration projects have
been undertaken in recent years. These projects
include efforts by NY/NJ Baykeeper, which
depend on citizen stewardship to seed and
monitor oyster populations. The Bronx River
Oyster Restoration Pilot Study by DPR was
successful, and the Department of Environmental
Protection (DEP) has placed an oyster
bed and reef balls in Jamaica Bay to evaluate
oyster growth, survival, and reproduction as
well as water quality and ecological benefits.
The findings of this pilot study will inform future
atteattempts to restore oyster habitat in the Bay.

About 150 turtles crawled onto the tarmac at New York's Kennedy airport Wednesday in search of beaches to lay their eggs, delaying dozens of flights, aviation authorities said.
The migration of diamondback terrapin turtles happens every year at Kennedy, which is built on the edge of Jamaica Bay and a federally protected park. In late June or early July the animals heave themselves out of the bay and head toward a beach to lay their eggs.

Marine Nature Study Area, Oceanside 20 May Joe Giunta and I (Sy Schiff) joined by George Form, Debbie Martin and Joe Viglietta spent the morning looking at marsh birds. Arriving before the Spring high tide, the water helped push the marsh birds out of the cuts and into the gher areas. CLAPPER RAILS were widely scattered (we saw at least 6), calling and walking about. Both SALTMARSH and SEASIDE SPARROWS were singing and we had brief but satisfactory views of both species. But the best was a WHIMBREL that only Joe G. and I got to see before it walked behind the vegetation at the edge of the marsh and could not be relocated. Other birds of interest were a GREEN HERON, WILLOW FLYCATCHER singing from the golf course and a group of CEDAR WAXWINGS in the trees by the parking lot. The second OSPREY chick hatched today, the first on Wednesday.

8. How many eggs do Canada geese
usually lay in one nest?
The number of eggs laid by one goose
in a nest can range from 1 to 10, but the average for giant Canada geese
(Branta canadensis maxima) is
between 5 and 6. The goose lay's one egg per day. If more than one
goose is laying eggs in a nest, as sometimes occurs when geese are nesting close
to each other (such as on an island), occasionally 15 or more eggs will be found
in a nest. These nests, which are referred to as "dump nests" because 2 or
more hens are laying or "dumping" eggs in them, are seldom incubated by any of
the geese that laid eggs in them.
src
Geese start nesting at slightly different dates in different areas; earlier in southern areas and later in northern areas, ranging from March through June with peak activity in April and May in most of the United States. ... Addling means "loss of development." It commonly refers to any process by which an egg ceases to be viable. Addling can happen naturally when incubation is interrupted for long enough that eggs cool and embryonic development stops. Humans addle where they want to manage bird populations. ... In Canada geese, eggs that are less than 14 days old can be addled humanely. Beyond that time, and when the eggs first begin to float when placed in water, humane treatment of the developing embryo [appropriate humane euthanasia] must be considered. src
After hatching, there is an amazing change in the attitude of the gander. Where he would previously chase off any other geese in the area, he now becomes much more tolerant of them. Indeed, if there are other clutches of goslings in the area, they will often group together in flocks called "cre src
ches" and be looked after by all the adults.The female Tree Swallow is the only female North American passerine that retains her immature plumage into her first breeding season and sometimes into her second. (Stokes & Stokes 1996). Her immature plumage is quite brownish, but may show some blue-green on the back and wings (Turner & Rose 1989). src

At 7mm (0.27 inches) long, Paedophryne
amauensis may be the world's
smallest vertebrate - the group that includes mammals, fish, birds and
amphibians. The researchers also found a slightly larger relative, Paedophryne
swiftorum. Presenting the new species in PLoS
One journal , they suggest the frogs' tiny scale is linked to their
habitat, in leaf litter on the forest floor.
Before the Paedophrynes
were
found, the title of "world's smallest frog" was bestowed on the Brazilian
gold frog (Brachycephalus
didactylus)
and its slightly larger Cuban relative, the Monte Iberia Eleuth (Eleutherodactylus
iberia).
They both measure less than 1cm long.
The smallest vertebrates have until now been fish.
Adult Paedocypris
progenetica, which dwells in Indonesian swamps and streams, measure
7.9-10.3 mm long.
Male anglerfish of the species Photocorynus
spiniceps are just over 6mm
long. But they spend their lives fused to the much larger (50mm long)
females, so whether they should count in this contest would be disputed.
Paedophryne amauensis adults
average 7.7mm, which is why its discoverers believe it how holds the crown.

Took the best pictures of Starling so far. <1> <2> <3> <4> <5> <6>
This (probably male) Starling is looking forward for breeding: less speckled, iridescent green and yellow-orange with a blue-grey base bill.
WWear Related Plumage Change: The white tips of the feathers that we see as spots (in winter) become worn and gradually disappear, so that the bird can change its plumage/aspect from one season to the next without molting which is very costly.
Moulting occurs once a year, in late summer after the breeding season is finished; the fresh feathers are prominently tipped white (breast feathers) or buff (wing and back feathers).
Its molting strategy is complex basic (House Sparrow too), typical of temperate-zone songbirds that are residence and short-distance migrants. Prebasic and preformative molts occur mainly on or near the breeding grounds, between the end of breeding season and the onset of winter.
Photo found on the book: first-cycle Starling in molt

In a brief stop at Ft Tilden, in Queens/Brooklyn, I saw 2 Red-shouldered Hawks, one adult and one juvenile. The juvenile at least has been seen in
the area within the last week so the birds may be hanging around there. I
also saw the adult perched off Flatbush Avenue opposite Floyd Bennett Field
as I was driving out making it, at least, a true Brooklyn bird.
Also of note at Ft Tilden, and also seen by Eddie Davis, was the continuing male Harlequin Duck near the fisherman's parking lot. Additionally, a large flock of Snow Buntings was working the island.
NYC Audubon Trip - Snowbirds of Floyd Bennett Field & Fort Tilden, Queens
Sunday, February 6, 10:30am-4pm
Guide: Gabriel Willow
Winter brings many rare birds to NYC that can't be
found here at any other time! Perhaps most exciting are the "snow birds"
of the Arctic tundra that can occasionally be found in tundra-like
habitats further south, such as snow buntings and snowy owls. We will
travel to Floyd Bennett Field in search of these and other winter
visitors (such as horned lark, tree sparrow, and rough-legged hawk). We

Snowstorm Shatters New York City, Philadelphia Records (January 27,
2011; 9:00 AM)
The recent storm total snowfall in New York City was
19.0 inches. The 12.3 inches that fell alone on Wednesday broke the
day's long-standing snowfall record of 9 inches from 1871. 總降雪量(19in),
單日降雪量(12.3in).
The storm also pushed the month's snow total to 36.0 inches in
New York City. That makes this January the snowiest on record, bypassing
January 1925 and its 27.4 inches.
This January is also now New York City's second all-time snowiest month,
falling short to February 2010 and its 36.9 inches.

Common: 1/exposure = 35mm focal length; No digital zoom. So
to get sharp picture, avoid digital zoom and even long optical zoom.
More tele, larger F-stop value (less light in) and faster shutter
(reduce blurring), then have to increase ISO and under bright light.

The The Dery Bennett New Year's Day Beach Walk: http://www.littoralsociety.org/local_field_trips.aspx , leaded by Don, ALS.
Parked at Studio 6. Perhaps around 50 people joined the kick-off. First saw Great Black-backed Gull flying over us. Then a group of Brants before starting the walk.
Some sea ducks, perhaps Scoters or Eiders.

如果海鷗離開水面,高高飛翔,成群結隊地從大海遠處飛向海邊,或者成群的海鷗聚集在沙灘上或岩石縫裏,則預示著暴風雨即將來臨。
海鷗之所以能預見暴風雨,是因為海鷗的骨骼是空心管狀的,沒有骨髓而充滿空氣。這不僅便於飛行,又很像氣壓錶,能及時地預知天氣變化。此外,海鷗翅膀上的一根根空心羽管,也像一個個小型氣壓錶,能靈敏地感覺氣壓的變化。 src: http://tw.myblog.yahoo.com/frank-blog/article?mid=6875&prev=6876&next=6848

Last year they saw Owl. And may see Peregrine Falcons nesting on the bridge.
Hi all, Anne Swaim, Larry Trachtenberg and I birded Montauk for a few hours today. At about noon, we saw a lone BLACK VULTURE fly low over the Montauk Point SP parking lot. I haven't spent much time seawatching at Montauk Point, but it seemed that there was a very large number of scoters and eiders flying with the wind past the point today. We estimated perhaps 50 birds per second on average, and the stream was going strong both when we arrived and when we left two hours later. If you do the math, that's 360,000 birds in just that two hour period, and the species composition was roughly 50% Black Scoter, 20% White-winged, 20% Surf, and 10% Common Eider. I've posted a short video that I digiscoped with my phone (http://flic.kr/p/95sWsF), but it doesn't do the spectacle much justice. Is this a typical occurrence for Montauk, or perhaps related to the recent storm? Also of note, a few RAZORBILLS could be seen flying with all the scoters. A group of about a dozen AMERICAN PIPITS were hanging around the point too. Good birding, Benjamin Van Doren White Plains, NYpre>

Maximum observed life spans of some organisms thought to be negligibly senescent:
What animal can count?
List (with the max. they can count)
-----------------------------------
Social insects - honey bees (4)
Mammals - dolphins (?) or monkeys (4 for chimps)
Birds - Crows (9 or higher, 16?), pigeons (9), Cormorants (8), parrots (6), European Robins (12?) and probably more (Many birds are also able to detect changes in the number of eggs in their nest.)
Note:
European Robins have some innate ability to discern between small numbers as three and four and through trial and error, they can train themselves to identify numbers up to 12.

Crows and Ravens, solve problems and are highly social creatures. Crows show tool-making and tool-using behavior. Crows and Ravens can talk with each other, count to 9 (compared with 4 for chimps), and steal. They play—sliding down long snow banks, for example. The birds covered about 10ft each time and returned on a second day for more fun and games. Crows are the most social and intelligent species of all birds. Crows mate for life and the young stay with the family unit for up to five years and help the parents raise siblings.

Many animals can tell a larger quantity from a smaller quantity. For instance, many animals can pick a pile with six pieces of food instead of a pile with five pieces of food. Children who have not learned how to count yet, can do the same thing. But being able to notice differences in quantity is not the same thing as counting. Scientists now believe that certain birds and animals can actually count. In one experiment, a pigeon was offered one grain at a time. All the grains were good to eat, but the seventh grain was always stuck to the dish. After a while, the pigeon learned to count to six grains, and when the seventh grain was offered it refused to peck at it. This was real counting! In another experiment, a chimpanzee was taught to pick up one, two, three, four, or five straws and hand over the exact number of straws that was asked for. But this was as far as this chimpanzee could count. It always made mistakes above five.
