Warbling Vireo (I think)
Vireos are a tribe that somehow I just don’t encounter very often. We have what used to be the Solitary Vireo nesting here in Maine, now split into three species, of which ours is the Blue-headed, as well as the Red-eyed and Warbling…we can also get the Philadelphia in migration…but, honestly, I just don’t see them here on the seacoast of Southern Maine very often. So, when I encounter Vireos on my travels, I am never quite certain of the id. This bird is in the Rio Grande Valley of south Texas, at Santa Ana National Wildlife Refuge south of McAllen, right on the border, and is probably a migrating bird, just passing through on its way south for the winter. I am pretty sure it is a Warbling Vireo.
