Warbler Guy, any name changes by the American Ornithologists' Union this summer? Did the AOU bird name changes happen to any wood-warblers?

Channee, the short answer: "No" changes among wood-warbler species (either scientific or common names) via the recent July publication of the AOU's latest taxonomic proposal changes.

That written, a couple of interesting votes occurred by the AOU committee in relation to other songbird taxonomic change proposals:

1. In a slight upset, the presumed lump of Hoary and Common Redpoll failed as a proposal. More study was deemed necessary to decide if these two species should instead be considered as one.

2. A proposal that passed:

The Western Scrub-jay is now separated into two species: California Scrub-Jay and Woodhouse's Scrub-Jay.

Read all about it, below, courtesy of Audubon Magazine (and the author Kenn Kaufman):

Western Scrub-Jay is now split into two species: the California Scrub-Jay(Aphelocoma californica) and Woodhouse’s Scrub-Jay (Aphelocoma woodhouseii). Birders have long recognized that these widespread western jays come in different flavors: a darker, more rich color in California, Oregon, and southwestern Washington, and a somewhat paler, grayer type in the interior West, from Nevada east to Texas. Many field guides already illustrate them separately as “coastal form” (or “Pacific form”) and “interior form.” They do hybridize where their ranges come together in western Nevada, but studies have shown that such interbreeding is very limited. So now they will be officially recognized as separate species.

Birders who have traveled widely in the West have probably seen both of these already, and will net an automatic “armchair lifer” from the decision. If you’ve already seen them, you can go ahead and count them.
