Thanks Carma, for sharing this!
Yellow-rumped Warblers were extremely thick at E.E. Wilson Wildlife Area all through December, and on into early January when I was still encountering dozens, sometimes over a hundred, along my 7.5 mile "raptor walk" route.
But strangely I haven't come across any locally in February (despite doing two full raptor walks, and numerous shorter walks) or so far in March. I see from eBird that a few people have been finding small groups of 1 to 4 birds here and there, but nothing like the numbers that I was encountering in December or January.
Nice to know that birds in full breeding plumage are starting to appear!
