Please name at least one field mark that supports your identification.

As an added bonus, can you identify the insect in this bird's beak?

I think this is a chestnut-sided warbler. It's the color on top of the head that gives it away for me. I'm not an insect person, so I have no idea what the insect is.

I didn't see it at first, not being very familiar with the bird, but now that you've pointed it out I'm pretty sure you're right: Chestnut-sided Warbler. Besides that color on the head, the eye-ring seals the deal.

Great shot!

No, No, Ridger, although I see the resemblance... That's not george, it's George's brother Jeb.

:)

It is a flycatcher.

Anatomical feature: It has a fly in its beak.

Bird: Chestnut-sided Warbler because of the yellowy-green head, grey face and white eyering.
Insect: ?? Green Lace-wing sp.?

you got the bird species but i don't know the insect species, but wondered if any of you might, which is the reason i asked.

Looks to me like that poor bird hit a window or something and someone placed a bug in its beak after for the photo.

Poor bird. She does not look healthy.

You can request IDs of arthropods photographed in the U.S. at BugGuide.net. They add the photo to their identification guide. I've done this several times and learned some interesting things.

I think it's too small to be a green lacewing. I like the leafhopper theory, but I'm wondering whether it could be an aphid.
