Yellow-bellied Flycatcher confirmation

Recommended Posts

douginBC    89

First, thanks to psweet for answering my question about possible gray on worn YB Flycatchers.

I've put 4 (bad) photos on Flickr hoping for further confirmation. Here's the links - which just 'automatically imbedded' as photos so maybe they'll show up immediately when I post this?

Bird seen August 12 north of Golden in SE British Columbia. I see a yellow throat, strong eye ring, short tail and dark wings, etc. but the head sure looks gray. Would appreciate some confirmation, or not, before doing my eBird entry for it.

Thanks!

Edit: Oops, posted two of the same shot; adding the other one, which may be the most useful one:

Given the likelihood of Pac-slope Flycatcher, I think I'd want to see a good shot of the closed wing or hear a recording before I could agree with Yellow-bellied there.

Thanks psweet. I sort of ruled out Pac-slope because I have never seen one - and I have seen a lot of them - with a round eye ring; always had a very conspicuous tear drop shape. Also this bird's tail looks too short for one. In the meantime I'll squint again at my not-good photos and seen in any show the "closed wing" but I don't think so. What would be the difference?

P.S. This bird was silent.

The difference is a bit subtle. If you look at the base of the secondaries, there's a black bar before the feather edges turn pale. In Yellow-bellied, that bar is much wider than in Pac-slope/Cordilleran. Below is the reference. They actually discovered a Pac-slope (I believe the DNA suggested that, anyways -- the authors weren't willing to decide between PS and Cordilleran on that bird) in the collection at the Field Museum that had been mis-labeled (in the hand) as a Yellow-bellied. I think (and I'm definitely not alone in this) that we are way too confident as birders in our abilities to ID these guys in the field. (That would include all the empids, btw, not just these yellowish ones.)

Thanks again psweet. Looked at that paper. Definitely have no photos good enough to see that difference.

Agree on the ID challenge! Wish they would sing or at least call all year. When they are silent they usually end up unidentified by me unless I get a really, really good look and, preferably, get some photos to study. Even then, for the most obvious example, all silent Traill's are Traill's.

Back to this bird, that very smooth eye ring still has me thinking YB over Pac-slope...

Haha. First I must convince myself! Then it is on to the eBird reviewer. In the meantime I'm hoping to get some feedback from other BC birders on whether or not they have seen Western - I mean Pac-slope - flycatchers with such smooth eye rings. Thanks again for that link, your help and your caution.
