Hulls gulch- Boise
Reminds me of what Edward Abbey , one of my heroes, said” the hermit thrush is one of the most beautiful sounds in nature”.
Any other favorites?

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
assumption this early in the winter, do Herring Gull
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.That bill is pretty long but the extensively pale base
this early in winter doesn’t really fit anything this bird
could be (any hybrid with Glaucous would have paler
primaries). Aside from the bill what’s wrong with this
bird for Herring Gull? My guess from these photos is a
Herring with unusual bill.Cliff
