Abstract
This is the 25th supplement since publication of the seventh edition of the Check-list of North American Birds (American Ornithologists’ Union [AOU] 1998). It summarizes decisions made between April 25, 2024, and April 30, 2025, by the American Ornithological Society’s (AOS, formerly American Ornithologists’ Union) Committee on Classification and Nomenclature—North and Middle America. The Committee has continued to operate in the manner outlined in the 42nd Supplement (Banks et al. 2000). During the past year, Andrew W. Kratter left the committee.
