[Tweeters] Yellow-Rumps

[Kevin Lucas]

Here in Yakima I sometimes see all three plumages of Yellow-rumped Warblers
on the ground here, most often when there is much snow cover and few
patches of exposed ground. I also see them foraging on the ice/snow shelf
edge of the river, but mostly eating Russian Olive berries and sallying for
aerial prey, including over the river.

Especially at "Poppoff" (how we refer the southernmost section of the
Yakima Greenway Path) all three varieties of Yellow-rumped are present,
even more so in the winter. We have Audubon's, Myrtle, and many
intergrades. I can distinguish between the calls of Myrtle and Audubon's,
but not the calls from intergrades, which can sound like either, so I
refrain from "identifying" them without also seeing them well. I've never
heard a call that sounds like Audubon come from one that appears as 'pure'
Myrtle, nor vice versa.

Good Birding,
