As the buds pop now in New England, we are in warbler season - one of the birder's high-points of the year. Odd factoid - New York's Central Park is one of the best locations for migrants in the US - and I mean bird migrants. And one of the best spots for odd species - and I mean odd bird species.
The Yellow-rumped is another abundant migrant, but unique as a warbler that can winter in the north, living on bayberries which they have a unique ability to digest.
We used to call them Myrtle Warblers - some of us still do. Bright yellow at base of tail is diagnostic. Found across the US and Canada. Click here: All About Birds
