It is an oft-quoted fact that the humerus in many birds is hollow and 
has an air passage connected to the air sacs in the breathing mechanism.

Is there any anatomical evidence for an extension of these air passages 
beyond the humerus to the radius and/or ulna or even beyond?  I realize 
that this would be anatomically difficult, but the connection of the 
airways to the humerus is already quite an interesting piece of evolution.

The texts I have checked make no mention of the possibility.  If you have 
a pointer to a suitable reference it would be appreciated.

There are currently two Eurasian Wigeons at Charleston Slough
which is just adjacent to Mt. View Forebay (Coast Casey Forebay)
where Jeff Finger reported seeing "several."  One is an adult
male and the other an immature male.  Males seem to outnumber
females by a good measure possibly because of difficulty of
identifying the females.

The SF Bay Area usually has Eurasian Wigeons in fair numbers.  Up
to 5 at Bolinas Lagoon, 3-4 at San Leandro Bay, 1-2 in Palo Alto
and Limantour and scattered individuals elsewhere.  One was
Abbott's Lagoon last month.

Wherever American Wigeons are found in numbers a few Eurasian
Wigeons are almost expected.  Christmas bird counts have recorded
up to 30 in the Gray Lodge Area in the Central Valley in some years.

They are more common in midwinter actually.  Also many of the
1st year males don't look too obvious until January, so the birds
are easier to pick out then.  By December they seldom appear on
the Northern California Rare Bird Alert because there are too
many to itemize.

I can't say exactly, but here in Indiana Cardinals, Blue Jays and
House Finches do not migrate.  Robins are already fairly scarce around
here.  I do not feed birds in the summer, I just keep the feeders full
during the winter months so I can't really speculate on Robins not
leaving.  If I had a guess though, I say that birds that migrate, will 
continue to migrate even if you offer them food.  Kind of one of those

TB> I doubt there are any breeding records for NJ peregrines.

Formerly one of the largest concentrations of breeding Peregrines
was along the Palisades of the Hudson River, mostly in the New
Jersey section.

These populations were wiped out in the 1950's primarily by
falconers who continually took the young from nests that were
productive despite DDT contamination.  If it were not for
unscrupulous falconers, we might have had a healthy wild
population that would have been resistant to DDT.

Half a continent away, migration seems (a) early and (b) somewhat above
average in numbers.  Birds which have come through our banding station
in the Rio Grande riparian area in Albuquerque significantly earlier than
usual (based on about 13 years of banding in the same location) include:
House Wren, Yellow-rumped Warbler, Lazuli Bunting, Green-tailed Towhee, 
Clay-colored Sparrow, White-crowned Sparrow (both "Mountain" and 
"Gambel's" ahead of their respective schedules), and "Oregon" junco.

We already have our best fall ever for Lazuli Bunting (139 banded;
previous best was 106) and our second best for Chipping Sparrow,
significant because we band more chipping sparrows than any other species 
(933 so far with a month to go if my guessing is correct).

You don't actually have to do these experiments over again for

Yes. Eurasian Wigeon is rare but regular, the most likely place in the lower
48 states to see it is in the Bay Area in fall. (The yellow crown stripe is
not diagnostic. Am. Wigeon may also have a yellow crown, and a blueish bill.
But if you see them side by side, they are obviously different - E.W. has
brown cheeks, gray flanks ; A.W. had gray cheeks, brown flanks. Also, A.W.
is obviously bigger.) Congratulations.

Might as well plug my old roommates music.

Joe Weed is an acoustic string musician extraordanaire.  Several years ago
he release a CD of music based on bird calls/songs.  The name of the album
is called "Waltz of the Whippoorwill". Each song is based on the song/call
of a different bird.  Joe plays violin, guitar and mandolin.  Joining Joe
is his wife Marty Kendall on cello and, I believe guitar.  There are also
a few other guest musicians including world class mandolinist David Grisman.
The album has sort of a newage feel to it.  He has at least one other CD
of similar music.

I was able to find some historical information on the Peregrine Falcon in
Pennsylvania in W.E.Clyde Todd's _Birds of Western Pennsylvania_ (U.  of
Pitt Press, 1940).  Todd says (page 161)

. . . On the Atlantic coast it breeds as far south as the Palisades of the
Hudson River in New York state, but in the mountains it is known to nest as
far south as Tennessee.

     This hawk is fond of rough, wooded country and avoids the flat and
cultivated areas; thus it is sparingly distributed as a breeding bird in the
ridge and valley region of our state, east of the crest of the Alleghenies
proper.  In this rough and broken country, cut up by minor mountain ridges
with valleys between, the Duck Hawk finds congenial territory with plenty of
nesting sites on the cliffs and no dearth of suitable prey.  Warren cites
several nesting records from eastern Pennsylvania.  He quotes T.L.  Hzzard
to the effect that the Duck Hawk breeds in Allegheny County [ie.
Pittsburgh], but he has no further evidence to offer.  The first nest known
from our region was the one discovered by A.K. Pierce near Grove Run,
Clinton County, on April 21, 1894, and from which he took a set of eggs.
T.D. Burleigh writes that in April, 1919, he saw a pair of Duck Hawks
along the Susquehanna River near Hyner, in the same county.  In the spring
of 1921 G.M. Sutton and S.S. Dickey visited two nests, previously located
by Mr. Dickey in the mountains of Huntingdon County.  Even at this late date
it is not wise to disclose the exact localities of these nests, out of
consideration for the birds themselves.  Probably a thorough exploration of
this general region would discover more nesting pairs, although they are
doubtless widely scattered.  O.P. Medsger writes that in May, 1914, he
learned of a nest on a cliff along Jacobs Creek, in Westmoreland County,
about two and a half miles above the town of the same name.  From the
description he was convinced that this nest belonged to a duck hawk.

     Elsewhere in western Pennsylvania the Duck Hawk is know only as a casual
visitant during migration.  . . [end quote]

I have seen this small warbler type bird three times in the last two weeks.
It is smaller than most warblers. I've seen it among black throated greens
and chestnut sided warblers . It is usually in low shrubs never more than
8 or 10 feet above the ground. It is solid gray above(no stripes or wing bands).
and light gray or white below and no streaks. The most noticeable feature
are the brilliant yellow feathers under the tail and a single bb sized tick
of brilliant yellow on each wing. Afew appeared to have a blush of red on the 
breast under the wing. 

Any guesses?

Although I do like to post without a specific citation, I will anyhow. (8

The reason many birds are still affected by DDT is that it is still in the 
ecosystem.  DDT does not deteriorate very quickly and takes some time to
travel through the soil, to the water, through the various critters into
the birds.  They estimate that although DDT was banned in the 70s (right?)
it is at its peak or just past it now in its effect on the ecosystem.  It just
takes time for nature to clean its pipes, especially with something as
nasty and pervasive as DDT.

Again, I apologize for not having the specific article I read this information

     To answer your two questions.  Beebe and Webster, in
North American Falconry and Hunting Hawks, do contribute DDT and
other pesticides to the decline of the Peregrine after WWII.  Seems
that the poison made them sterile along with killing some in high 
doses ingested with prey.

     As for the captive breeding, NAFHH does not say, but my guess, 
keep in mind GUESS, would be the Continental Peregrine (F.p. anatum)
or the Peale's Peregrine (F.p. pealei) in that order.  The Arctic 
it seems would be too hard to obtain a significant number to breed
and the tundra peregrine was discovered sometime after WWII and is still
rare to my knowledge.

Actually, most early breeding efforts were done with falconry birds
and were largely unsuccessful, principally because lots of falconry
birds were tundrius peregrines trapped as first-year (passage) birds.
Successful breeding commenced when tundrius were taken as young
from the Arctic.  There was considerable flak about releasing
tundrius peregrines in habitat formerly occupied by anatum
peregrines, and many of the early releases had other races of
peregrines in their pedigree.  The efforts have shifted now to
the much larger anatum race for reintroduction.  The abundance
of N.A. peregrine races is tundrius, Peale's, and anatum in
descending order.  The anatum race is the most widespread as
a breeding bird, and the tundrius is the most migratory.  All
three can be found at one season or another here in Washington.
