Black-throated Gray Warbler


Black-throated Gray Warblers are common breeders from northwestern Mexico to British Columbia, and wintering mostly in Mexico. Guzy and Lowther (2012) report that this warbler is relatively tame and easily approachable. Not a whole lot seems to be known about  this warbler’s biology. I wonder about the purpose of the yellow spots behind the bill. In some other birds, spots like these are used to sight down the bill and aim for prey. This individual is the only one I’ve seen since moving to Olympia. I banded this bird on 2 May 2019.
