Subject: Short-billed Dowitcher (subspecies hendersoni)
From: Jean Iron <jeaniron(AT)SYMPATICO.CA>
Date: 18 Jul 2005 8:24am
----INCLUDING text/plain MIME SECTION----
Yesterday, July 17, we observed a flock of southbound adult Short-billed
Dowitchers near Toronto, Ontario. Most were the subspecies hendersoni,
whose core breeding range is central Canada west of Hudson Bay. The core
breeding range of nominate griseus is Quebec. Hudson Bay and James Bay
almost divide the two subspecies. However, the population west of James Bay
in northern Ontario is an area of intergradation between griseus and
hendersoni. See photos of several hendersoni and a possible intergrade
griseus x hendersoni.

Short-billed Dowitcher (subspecies hendersoni) reply by Kevin Karlson
The possible intergrade of hendersoni/griseus posted on Jean Iron's
website looks like a typical griseus Short-billed Dowitcher, with the
only possible hendersoni plumage feature being a slight wash of orange
color extending into the lower belly. However, I have photographed a
number of griseus in late May in NJ which have a smattering of orange
color extending into the undertail coverts as well as the leg feathers.
These birds were classic examples of griseus, and exhibited no
hendersoni characters, so a slight bit of orange color to the lower
belly and undertail does not automatically raise the question of
intergrade. The heavy barring on the lower flanks, the concentrated bars
and spots on the upper flanks and the dense spotting across the upper
breast are all plumage characters typical of griseus in breeding
plumage. With the almost head-on angle of this bird and the lack of size
comparison to hendersoni dowitchers, it is difficult to see if it is
slightly smaller than nearbly hendersoni. Griseus averages slightly
smaller than hendersoni, and is often noticeably less "bulky" when seen
near hendersoni. They also show an overall more muted appearance on the
upperparts than hendersoni, due to the less boldly marked and more
narrow upperpart feather markings and fringes, which is somewhat visible
in this photo, even at the almost head-on angle.
I have also noticed recently that griseus seems to begin and undergo its
fall molt sooner than hendersoni, with some birds showing substantial
head and body molt by early-mid August, while many hendersoni are still
in mostly full but worn breeding plumage in early-mid August (including
some retained, older non-breeding wing coverts, that were not replaced
during its' spring alternate molt).. Most griseus are in active head,
body and scapular molt by early August, with many hendersoni still
showing mostly full but worn breeding plumage. Griseus is highly
variable in breeding plumage in respect to the amount of orange
coloration on the breast, with some showing a good amount of orange
color from the upper breast to mid-belly and others showing only a
slight wash of orange color to the upper breast. This range of variation
occurs in adult birds, and is not related to first summer plumage only,
where some birds show partial breeding plumage while others show mostly
nonbreeding plumage in June and start to molt head, body and (somewhat
later)flight feathers soon afterwards.
This is a point that was totally overlooked in the recent article in
Birding magazine regarding the ID of Long and Short-billed Dowitchers
using active flight feather molt and presence of nonbreeding plumage as
ID tips at inland summer/fall migration locations. First summer
dowitchers present a very different set of parameters with regards to
molt schedule and timing than adults, and could affect the accuracy of
the articles hypotheses. I don't have any experience in overland
migration of hendersoni SB Dowitchers, but would be very interested to
hear from others regarding the presence of nonbreeding first summer
dowitchers at inland spring and summer/fall stopover sites. If there are
a comparative number of first summer dowitchers at inland spring
stopover sites as there are in the mid-Atlantic region, and these birds
oversummer in these areas while beginning their molt to first adult
basic, then there are a few more points that need to be covered related
to the identification of SB versus LB Dowtichers with respect to active
flight feather molt in migration and the presence of nonbreeding
plumage dowitchers inland that have started to actively replace primary
flight feathers and tertials. Many first summer SB Dowitchers migrate
part of the way to the breeding grounds, but stop at migratory staging
areas to start their much earlier molt to first adult basic plumage. The
molt schedule on first summer SB dowitchers starts sooner than and is
completed earlier than adult dowitchers (typical of arctic breeding
shorebirds), with some birds possibly replacing some tertials and flight
feathers from June through July while oversummering at or near spring
stopover locations. I have seen groups of up to thirty probable first
summer SB Dowitchers ( mosly griseus with a scattering of hendersoni)
stop their migration along the southern NJ coast in late May, with a
majority in mostly nonbreeding or partial breeding plumage. When I
photographed about a dozen of these birds on June 29, a majority had a
mixture of worn first winter nonbreeding feathers, nonbreeding
underparts, a few breeding scapulars and wing coverts, and a few new
fresh nonbreeding scapulars and tertials. Their overall appearance,
however, was mostly nonbreeding at a distance view. I observed this
flock a number of times during June to mid- July, but they left or were
lost in the numbers of adults that arrived in late July. These first
summer birds probably migrate south sooner than adults(possibly in mid
to late July), in conjunction with their earlier molt, since full
nonbreeding SB Dowitchers are not commonly seen in summer movements of
breeding adults. I am not sure whether flight feather molt is actively
undertaken at these stopover locations, especially inland sites, and
would be very interested to hear from observers who see nonbreeding SB
Dowitchers at inland sites over the next three weeks.
The photos of these dowitchers are beautiful, and the recent dialogue
has opened many new possibilities and questions regarding these special
shorebirds. I look forward to comments from others regarding inland
nonbreeding or partial breeding SB Dowitchers in spring and fall
migration, or especially oversummering birds in mostly nonbreeding
plumage (late dates -midJune - late July would be of special interest).
If you see these birds now or in the next few weeks, please note whether
flight feather molt is or has taken place, and the extent of this molt.
Thanks, Kevin Karlson

We added two more photos of the Short-billed Dowitcher considered by us to
be a possible intergrade griseus x hendersoni. The second photo was taken
20 seconds after the first in similar light, but shows a full side view.
The third photo is also a full side view taken 24 minutes later, but in
different light. Use link below to view photos.
http://jeaniron.ca/Shorebirds/2005/tribC.htm
The bird in question has characters of a nominate griseus Short-billed
Dowitcher as indicated by Kevin Karlson. In life it also showed additional
characters suggesting the influence of hendersoni that are not visible in
the photos: (1) The cinnamon color below was a similar shade to the nearby
hendersoni, whereas this color in griseus averages paler; (2) the cinnamon
color is more extensive than on typical griseus extending below the legs as
seen in the third photo; (3) the tail in flight showed about the same
contrast as the hendersoni, whereas griseus has a darker tail because the
white tail bars are narrower; (4) the size, bulk and bill length were not
different from nearby hendersoni; (5) spotting is sparser and more
extensive on hendersoni, but we have seen many individuals with numerous
neck spots and flank bars suggesting intergradation with griseus. In the
third photo note a few spots on the belly, which is a character of
hendersoni; (6) we have seen flocks of classic griseus in Quebec at this
season and the Ontario bird would have stood out as different among them.
We feel that there are enough hendersoni-like characters in the Ontario
bird to treat it best as a possible intergrade. Intergrade griseus x
hendersoni dowitchers are more frequent than is generally realized. For
those wanting to examine the best series of specimens of nominate griseus
from the core breeding grounds in Quebec, we suggest a visit to the
Canadian Museum of Nature (CMN) near Ottawa. The CMN and the Royal Ontario
Museum (ROM) in Toronto also have specimens of probable intergrades from
northern Ontario.

Subject: Mystery hawk in Trinidad
From: Floyd Hayes <floyd_hayes(AT)YAHOO.COM>

A photo of a suspected Red-tailed Hawk in Trinidad,
photographed by Courtenay Rooks, is posted at:
http://www.geocities.com/secaribbirds/ttmysteryhawk
Unfortunately the tail cannot be seen in the photo but
its description is given beneath the photo. This is a
potential first Red-tailed Hawk for Trinidad & Tobago,
and perhaps the first documented for South America.
I'm wondering whether Swainson's Hawk can be
eliminated. Any comments would be appreciated.

Given the "here today, gone next week" nature of many mid-continent
wetlands, I would be surprised if attempts by 1st year SBDO summering in
my region (of which I'm unaware) are anything other than anomalies soon
selected out of the gene pool. It's certainly not a regular molt
strategy that it is at coastal locations. Coastal wetlands, unlike many
in the interior, are relatively "permanent" and provide staging areas
that can sustain the high-energy requirements of feather molt on an
annual basis.

Posting of these or similar photos would be extremely helpful for those
interested in dowitchers, because published information about 1st-year
plumage is so limited (as are the opportunities for observing live birds
in this plumage), and web photos are nearly (?) non-existent.

Perhaps there is data from the interior on over-summering 1st-year SBDO
that I'm unaware of, but what I know of SBDO migration in my area
(IA/MN) leads me to the conclusion that it doesn't occur here:
In Iowa over the past 15 years, the median last departure in the spring
and first arrival in the fall (taken from seasonal field reports in Iowa
Bird Life) are 23 May and 7 July. Record late spring dates are 8 June
and 13 June, record early fall dates are 26 June and 2 July. There are
no records of SBDO seen between 13 and 26 June.
In Minnesota, up to 2001, the average last spring departure and first
fall arrivals were 28 May and 2 July. There were no records of SBDO
observations between 13 June (record late) and 24 June (record
early)(Bardon 2002).

Subject: Juvenal Franklin's Gull
From: Robert Hughes <rhughes.enteract(AT)RCN.COM>
Date: 20 Jul 2005 6:52am
Today, July 20, I saw and photographed a Franklin's Gull in full juvenal
pluage at Montrose Beach in Chicago. In over 25 years of birding I've never
seen a juvie Franklin's Gull along the Lake Michigan lakefront, where
Frankilin's Gulls are regular, or anywhere else for that matter. I was
under the impression that first year Franklin's molt into first basic
plumage before migrating south. Also, this bird has pinkish legs - the
Grant gull book describes the leg color of juv. Franklin's as black. I
posted a photo of this bird on the Surfbirds Web site.

Forwarding for Bob Wallace:
Greetings, Shorebirders!
We are pleased to announce the formation of a new Listserve, hosted by the
University of Georgia, that also hosts Georgia Birds, and Pelagics-SE.
Shorebirds (or Waders, if you prefer) are a unique and fascinating group of
birds, because of their wide ranges throughout the world, and some of the
most impressive migrations of all birds, flying from the Arctic tundra all
the way to southern South America, Africa and Australia and back again, with
vagrant species turning up in many unexpected locations. They can be
confoundingly difficult to identify, with many similar species and
overlapping characteristics. And due to habitat loss of wetlands in
breeding, migration stopover and wintering grounds, many species are facing
severe ecological pressures and population losses. The focus of this
listserve is to create a worldwide forum for reporting the observation of
seasonal migration in differing areas, discovery of rarities, discussion of
identification problems, and for promotion of knowledge of conservation
issues concerning shorebirds.
As with other lists, please keep posts on the topic of shorebirds. Off
topic posts, such as general political comments, religion, flaming, etc, are
not allowed. Commercial topics are not encouraged, unless they are
announcements concerning upcoming events that feature Shorebirds. Please
use discretion as you would with other lists.

We commonly see juv Franky's in this plumage in July/Aug (well, common isn't the
right word, as the bird is rare here -- but the few seen each year during this
time are in this plumage) in WA. The pink legs do not look normal, though I
can't say I've checked specifically for this. By Sep, the birds are well headed
into first basic plumage. I can not say precisely when the transition occurs,
and of course, this likely varies from bird to bird.
Cheers

Subject: [BIRDWG01] Juvenal Franklin's Gull
Today, July 20, I saw and photographed a Franklin's Gull in full juvenal pluage
at Montrose Beach in Chicago. In over 25 years of birding I've never seen a
juvie Franklin's Gull along the Lake Michigan lakefront, where Frankilin's Gulls
are regular, or anywhere else for that matter. I was under the impression that
first year Franklin's molt into first basic plumage before migrating south.
Also, this bird has pinkish legs - the Grant gull book describes the leg color
of juv. Franklin's as black. I posted a photo of this bird on the Surfbirds Web
site.

HI:
A few years ago I e-mailed this group about variation in black-capped
chickadee songs over time and I was trying to find that e-mail in the
archives but COULDN'T! Has anybody else had problems finding past e-mails
in the archive and if so how did you get around those problems?

Greetings All
SBDO certainly over-summer in small numbers in WA (just a couple birds out of
the tens-of-thousands that pass through). Interestingly, though we get many
hundred LBDOs, WA has yet to have an oversummering member of that species. Most
shorebirds are supposed to have at least a few individuals, mostly 1st year
birds (but perhaps some that are unwell) that do a partial migration and summer
south of their breeding grounds. There is certainly interspecific variation in
this; in some species, such as BTCU, apparently all spend their first summer on
the wintering grounds (so you wouldn't expect 1st year birds part way to the
breeding territory).

Hi all:
Juvenile FRGUs can begin molting into first basic as early as July, as I've
photographed such on 22 July with some upper back feathers already replaced.
Additionally, these birds definitely start moving -- though, possibly not
migrating, just dispersing -- by mid- to late July.
Enjoy,

Subject: Odd tanager in Idaho
From: Cliff and Lisa Weisse <october(AT)IDA.NET>

I just received photos, taken in Idaho, of a male tanager
that shows some characteristics of Hepatic Tanager including
gray auriculars, split eye ring, and gray on the mantle.
I'd appreciate hearing opinions from anyone experienced with
Hepatic Tanager. Thanks in advance.

Hi All,
This bird looks more like a Summer Tanager in head shape and bill
proportions and color. I've never seen one with gray like that, but the
darker areas on a Hepatic Tanager are not quite so contrasting.
Good Birding,
Rich

Whatever it is the distribution of red pigment is clearly messed up -
mottled crown, gray throat etc. Could easily be a coincidence that the
pattern superficially resembles Hepatic. Either that or Summer could
have a similar pattern underlying the normally much more saturated
red.

Hi Cliff,
I just took a quick look at the photos, and it doesn't look right for a
Hepatic to me. It is very strangely marked, and I don't really know
what could be going on there, but the bird does not appear well to me.
Anyway, structurally it doesn't fit Hepatic - the bill is too long and
proportionally thin, and the same could be said for the overall body
shape. The tail and body appear too long. Also, the red color on the
rump and tail is too bright and orange-toned. The gray patches are too
flat gray and contrast too much. In Hepatic it's more of a duskier red
than a plain gray. It looks to me like a Summer Tanager with something
wrong with it's pigmentation or plumage.

Ian,
I get quite a few hits on BC Chickadee song variation when using the search at:
http://listserv.arizona.edu/cgi-bin/wa?S1=birdwg01 (requires logging in).
Try searching for 'chickadee' in the 'subject' line first.
You could also try searching for 'Paulsen' in the author field.
As pointed out by the listserve owner a while ago, it is important
that we include the species and subject area of our posts in the
'subject' field of our emails, in order to allow more accurate
searching of the archives for future users.
All the best,

Subject: Red-tailed Hawk?
From: Floyd Hayes <floyd_hayes(AT)YAHOO.COM>

Surprisingly I've received only three responses to the
mystery hawk in Trinidad. Two thought it was a
Red-tailed and one thought it was a Swainson's. I know
there are some hawk identification aficionados out
there so please take a look at the hawk when you get
the chance. I've posted the three responses
anonymously. If you'd like to be identified with your
response, please let me know. Again, the photo (with a
link to responses) is posted at:

Personally I think the large bill and dark patagial
mark point toward Red-tailed Hawk. Can an immature
Swainson's Hawk have a dark patagial mark?

Dear Floyd and all,
I have already posted my thoughts on the bird, but in response to the
Swainson's opinion, I think that the primaries are merely dark on top, which is
consistent with juvenal red-tail, the field notes that were taken at the time
clearly state that the patagial markings were wider than the trailing edge, this
is absolutely perfect for a juvenal Red-tail, their wing pattern is best
described as white with minimal brown mottling and a brown border, thicker on
the leading edge of the wing then on the back. I have sketches, or if need be, I
can find pictures on the internet. Also, to Floyd, I would suggest putting this
pic on IDFrontiers, a website specializing in bird idenitification, they'll
jump all over it.
