On my birding visits to southern Arizona, I've found the distinctive song of the omnipresent Bell's Vireo a constant accompaniment.

Both the male and female of the pair were attending to this eye-level nest while I watched it; the sexes do not differ in appearance, so I don't know which one is represented in the picture above. The picture below shows the female, as the male was singing nearby when I took it.
