Re: Hulls gulch- Boise

My favorite from Georgia, Virginia and Pennsylvania is the Carolina Wren. When my late wife and I traveled to Nova Scotia in the late 90s, we were fortunate to hear one of these wrens singing. My most recent wren sighting was a Rock Wren at the scenic overlook turnout along U.S. 20 about 10 miles south of the Camas County line in Elmore County.

Thank you both for your comments. I have been documenting your comments in my checklist for future reference. Thank you for this great learning opportunity not only for me but for many others I’m sure!

Re: Possible juvenile Western Gull at Jack’s Creek (CJ Strike Reservoir)

First, the bird is in juvenal plumage. Yes Herring Gulls
typically have blackish primaries and tail. Any hybrid with GWGU
would have paler primaries and typically with extensive pale tips.
Head shape with flat crown and eye set well forward are typical
for HEGU. Paleness of rump is hard to judge because some of the
photos are somewhat overexposed. Look at the amount of white in
the wing coverts in all the photos and there is considerable
variation in appearance. That said HEGU is quite variable and can
have a pale/whitish rump. While the bill is quite long and has a
strong gonys it doesn’t look bulbous like a WEGU to my eye. The
unusual thing to me is the amount of pale/pinkish on the bill this
early in winter. That’s unusual for HEGU and really so for GWGU or
WEGU.

Assuming it is a first winter, which I think is a good

primaries, tail, and secondaries get that dark? I am sure they
can but the flight feathers on this bird seem really dark.
Also, you can see the rump in a photo and it looks paler than
what I typically see on first winter Herrings. Maybe that is a
factor of the lighting. For me, the combo of big bill, rather
dark flight feathers and tail, blocky head, and rather pale
rump lead to this bird feeling a bit off for Herring for me.
Also, that this bird reasonably stood out from the other gulls
more than once.
For the record, I hold that loosely. I think it is
reasonable that it is a Herring. I just do not have much
experience with Western Gulls either or gull hybrids.

bird for Herring Gull? My guess from these photos is a
Herring with unusual bill.
