i'd be more inclined to think Empidonax sp., cf. this Least FC

It does look good for a Least Flycatcher but they are quite rare in CRica. Can this be a Yellow-bellied Fly instead?
I've been fooled a few times in Costa Rica with very pale looking wintering ones and this bird apparently shows an all pale lower mandible. Time for the Empidonax experts I guess.

...just zis guy, you know?
I agree with Empidonx sp. for this, but ugh, Empid ID from photos, however good, is not for me....
However, I suppose somebody who really knows his or her stuff could probably work it out (or, at least, narrow it down a lot) based on wing formula (& a generous dose of Pyle).

I have looked at the field guides of Honduras, Costa Rica and Panama for illustrations of wintering Empids.
I also saw a few Least Flycatchers in Honduras in November and they are fresh in my mind, and I feel drawn to that species for this photo. I also saw Hammond's and that was a bit different. I've seen the other Empids in the past in Central/South America. They are a fiendishly difficult group to separate.
I'm no expert, but the white eye-ring, contrasting grey upper and white underneath, noticeably short primary projection, impression of 'smallness', and that distinctive 'facial expression' give me a strong 'feel' for it.
That's my two pennyworth if it's any help.

The primary projection looks quite long, so Least is certainly ruled out and Yellow-bellied might be. The sharp contrast of pale wing bars to blackish wing rules out the smaller western species (as does the long primary projection). The complete eye rings should rule out Willow, leaving Alder and Acadian in play. The bill seems a wee bit short for Acadian, but I haven't seen numbers of that species for a while, so I'm happy with Empidonax sp.
