The 2017 American Ornithological Society Check-list Supplement was notable for the taxonomic decisions that were not made as much as those that were. Yellow-rumped Warbler and Willet were not split, but Cassia Crossbill was. We also saw the unprecedented lump of Thayer’s Gull into the holarctic Iceland Gull. Biologist Nick Block returns along with Birder’s Guide editor Michael Retter to discuss the changes made and the AOS’s process.
Also, we hear from Laura Erickson, author of the new ABA Field Guide to Birds of Minnesota, about writing the book and some of her favorite experiences birding in that part of the world. And I have a little something to say about the rise of millennial birders via this Maclean’s article.

Birders know well that the healthiest, most dynamic choruses contain many different voices. The birding community encompasses a wide variety of interests, talents, and convictions. All are welcome.
