Females are generally duller and have more buffy/brown/gray than males. I focus on males on this post, as they are much easier to ID in the field.
We will start with basic tips for the two common subspecies. Not really an important part of this timeline.Ģ016: Kenn Kaufman insults Yellow-rumped Warbler (Kenn has a sense of humor, right?)Ģ017: RIP Magnificent Hummingbird, flowery tarts get birds named after themĢ019: I am writing this article Identification of the Yellow-rumped Warbler Subspecies Confused? Do not fear! Most of this post is images.ġ972: Audubon's Warbler and Myrtle Warblerġ973: Yellow-rumped Warbler with 2 groups: Audubon's Yellow-rumped Warbler and Myrtle Yellow-rumped Warblerġ989: I was born. The difference? An intergrade is the product of two subspecies or subspecies groups, and a hybrid is the product of two species. Fun fact, an intergrade is not the same as a hybrid. The two subspecies that are the topic of this post, Audubon’s Yellow-rumped Warbler and Myrtle Yellow-rumped Warbler, can breed together to create an intergrade. For this post, we will only use the common English subspecies names. However, it is still split into four subspecies, with two of those subspecies being common in the US and Canada: c oronata (Myrtle) and auduboni (Audubon's). The Yellow-rumped Warbler (YRWA) is one species according to current* taxonomy. We can agree this is an amazing bird, with striking features. Photo: Zach Hutchinson/Flocking AroundĮveryone calm down. Kaufman called the Yellow-rumped Warbler-name "bland" and "unflattering." I say this to Kenn Kaufman: any bird that has "rump" in its name has a great bird name! Without "yellow-rumped," we might not have the affectionate nickname "Butterbutt." And certainly, it is a much better name than a bird being described using a surname like Cassin's, Baird's, or some other flowery tart (that is me throwing shade at the Duke of Rivoli - long live the Magnificent Hummingbird).Īdult Male Audubon's Yellow-rumped Warbler near Casper, Wyoming. The two "species" were lumped into the "Yellow-rumped Warbler." Some people, such as Kenn Kaufman, hated this move by the AOS (previously AOU). If you did not know that, you might have been born after 1973 (raises hand). The Myrtle Warbler and Audubon's Warbler were previously considered two species. If this post does not help you, don't blame me! I just type words and provide photos. if you want to try to improve your data records and ID skills, this may help you. You can call the birds in this post whatever you choose, but. Let me start by saying: I do not care how you record your birds in your field notes or eBird.
