I'm in the Dusky
camp on all photos. This is a really long-tailed Empid with a stubby
primary projection. The bill is mostly dark and a bit larger than I
would expect for a Hammond's. All those points are good for a Dusky.
The lower mandible should be noticeably more yellow for a Gray as well.
No chance for me that this is a Cordilleran--head shape is wrong, tail
is too long, eyering isn't the pronounced teardrop shape, even the
color, which should be brownish-olive tinged with yellow for a
All the photos show a first fall Dusky Flycatcher.
My guess 1, 2 & 3 are Dusky's.
#4 is Gray (longer bill).
Cordilleran Flycatcher. We saw a couple on the Western
Birding Symposium. That tear drop is the give away.
I think they are all reasonable candidates for Dusky
They all look like Dusky Flycatchers to me
- the bill is too long for Hammond's and too narrow for Willow or
Cordilleran. The tail length and short primary extension are both good
for Dusky. Gray should have more yellow on the lower mandible.
I think all your flycatchers are Dusky/Hammond's-olive back, gray head,
bold eye ring, grayish underparts. On #1 the extensively pale
bill is better for Dusky. A better mark is the condition of the
plumage-Dusky doesn't molt before migrating but Hammond's does.
So the ratty looking plumage in #2 supports Dusky. In #3 I can't
really tell if the plumage is old but the primary projection looks
short for Hammond's. #4 has short primaries and a long spatulate
tail (wider at the bottom than the top) which is typical of Dusky and
not Hammond's. Hammond's looks relatively shorter tailed,
possibly due to the longer primary projection. All have bills
that are a bit large for Hammond's and right for Dusky. So I
think all your birds are Duskys.
Empids are always a toughie, even with great photos like these. The
birds is a large billed empid, narrowing it to Cordilleran and Gray,
for this time of year and this location. Although I may be wrong
and the fact that I don't have a lot of time to look it over, I would
say the first 3 images are likely of a Gray
Flycatcher, while the 4th one may be a Gray
or even a Dusky. The jizz isn't right for
any of the birds, at least for me. I would lean towards Gray on
bird 4 cause the bill just seems to large.
If I had to say how sure I was, I would give the old 87.667777777% sure
of the bird ID.
