Small bird ID, Moab, UT, USA (1 Viewer)

Hi, folks.

This bird was seen in the San Rafael Swell near Molen Reef (not far from Green River, Utah). It was warbler-sized. The fact that there is no eye ring is what is throwing me off any IDs I might come up with. It was all smooth grey, and had a thin white strip on the wing. It was not a blue-grey gnatcatcher, and it was slightly larger than that.

Thanks for any help!

Of course, you're right. Thank you, KGS! Now I feel a bit dumb for even asking...he he he.
