YELLOWTHROAT
(Geothlypis trichas)
This is a gay little warbler that is abundant, at least in summer, across the United States and most of Canada wherever there are moist shrubby areas. It’s a permanent resident in southernmost United States and northern Mexico—and north up the Pacific coast to San Francisco. The yellowthroat lives in shrubs in moist areas, showing its distinctive markings to passersby. The female doesn’t have a black mask, but otherwise looks much like the male.
These warblers nest on or near the ground in moist areas and eat mainly insects, including plant lice; don’t look for them in the tops of tall trees. Adults are about 5 inches long. There are, of course, a lot of warblers over the continent, but the yellowthroat is widely distributed and widely admired. Keep your wet areas if you want to keep yellowthroats around.
YELLOW WARBLER
(Dendroica petechia)
Although similar to the goldfinch, this warbler lacks the black wings and tail. Its cheerful, bright call can be heard by urban dwellers from willows, small trees, and shrubs growing on wet grounds and in residential areas that contain an open growth of small ornamental trees.
A tropic winterer, he breeds from the tree limit in Canada to the southern states. When plagued by cowbirds laying eggs in its nest, this warbler builds a second nest on top of the first, completely covering the cowbird’s eggs, and any of its own in the bottom layer.
