Warbler Guy, what are the latest AOU species split proposals? Are Yellow-Rumped Warbler subspecies going to change in number?

(UPDATE: The article below is outdated, given recent name classification changes. Thus, see the 3/7/11 article here at this blog for an update in relation to the Yellow-rumped Warbler split into various subspecies.)

There's an excellent article to read All About It, Robert Z., if you go to:

That's a huge Web site address to copy and paste, I know.....but it's worthwhile reading.

You'll learn the potential options for classifying Yellow-Rumped Warbler that the American Ornithological Union (AOU) committee is debating.

Meanwhile, where I live in the Bay Area (CA), it's common to see two subspecies in many habitats during the non-breeding season:

1. Myrtle Yellow-rumped Warbler (Dendroica coronata coronata)
2. Audubon's Yellow-rumped Warbler (Dendroica coronata auduboni)
