Most of the the other changes which affect the ABA Area are changes to scientific names and the sequence of species on the checklist. The committee went against precedent with this decision: its often-voiced opinion that, unless there’s a species-level change, it’s not wise to tinker with long-established English names, didn’t win out this time. This reverses a committee action from 1957 and is also a nod toward the possible adoption of the species as the official bird of Canada.

Nowadays, it can be assumed that any change in taxonomy is due (at least partly) to analysis of new genetic data, so that is not always mentioned below. Species marked with asterisks (*) below are those which do not appear on the ABA Checklist. There, you’ll find photos, maps, and more detailed analysis of these changes. You can read all the proposals on which the NACC voted this year at . Later in the year, be sure to check out ABA’s annual “Check-list Redux” in Birder’s Guide to Listing & Taxonomy. Below is a brief rundown of those changes. The supplement, available here, details revisions to the NACC’s Check-list. Every summer, birders anxiously await publication of the “Check-list Supplement” by the American Ornithological Society’s Committee on Classification and Nomenclature of North and Middle American Birds (a.k.a.
