Hey everyone, I found a winter "Audubon's" Yellow-rumped Warbler in Crawford County today while running my section of the Retreat CBC. This is the western subspecies of Yellow-rumped Warbler. The International Ornithological Congress (IOC) considers this to be a separate species from "Myrtle's" Warbler (the eastern subspecies we always see here). The AOU has a pending proposal to split the species as well (in which case the ABA would also split it). I don't know if the WSO keeps records of this subspecies or not, but it's probably a good idea to keep track of them in case they are ever split. If split, it's likely that the AOU would divide Yellow-rumped into three species. Myrtle's Warbler (eastern), Audubon's Warbler (western), and Goldman's Warbler (Mexico). Goldman's is by far my favorite. I had a total of 40 species on the Retreat CBC today including two adult Golden Eagles. I'll post a summary of the count as soon as I have all the results in and tallied.
