The Yellow-rumped Warbler is known as the Audubon's Warbler on the West Coast and the Myrtle Warbler on the East Coast. What's the difference? The West Coast variety has a yellow throat and a large white patch in the folded wing. The East Coast version has a white throat and 2 white wing bars.
This little warbler, about 5 inches, flits around in coniferous and mixed woods, chirping constantly, seeking insects. Its song is more of a buzz than a warble.
The nest is a bulky assemblage of twigs, roots and grass placed in a conifer. The clutch consists of 4 to 5 white eggs that are speckled with brown.
