Definitely not a vireo, bill is way too small. From what I can see, I think
possibly I've narrowed it down to Orange-cr. Warb or imm. Tennessee Warb.
Then I'd eliminate OC--no breast streaking and the area around the eye is
wrong. Imm. Tennessee's are often still in juvenal plumage in March, they
have half an eyering which is below the eye, and bit of a supercilium.
Wouldn't bet much on my ID call, though. Tough bird, Marv!
Good birding, Mike
