ADD Short-billed Gull Larus brachyrhynchus, based on the taxonomic decision to recognize this taxon as a separate, North American species (Chesser et al. 2021) – as originally described – instead of as subspecies of L. canus, the Common Gull (known until now in North America as the Mew Gull). The Common Gull remains on the AKCL in subspecies L. c. kamtschatschensis (see Gibson and Withrow 2015:123). In Laridae, insert L. brachyrhynchus immediately following L. canus.

ADD Sandwich Tern Thalasseus sandvicensis, based on one bird present 10-11 May 2021 at Gustavus (N. Drumheller; photos AKCLC). In Laridae, insert Thalasseus between Chlidonias and Sterna.

ADD Naumann’s Thrush Turdus naumanni, based on four records — one bird present 22 October 1982 at Adak Island, Aleutians (C. F. and M. Zeillemaker; color sketch); one bird present 20-22 May 2000 at Attu Island, Aleutians (S. C. Heinl and others; photo AKCLC); one bird present 5 June 2015 at Gambell, St. Lawrence Island (J. L. Dunn and others; photos AKCLC, and see Lehman 2019:268); and one bird present 30 May 2021, at Shemya Island, Aleutians (Z. M. Pohlen; photos AKCLC). This species was transferred from the unsubstantiated list by a 2021 vote of the AKCLC. In Turdidae, insert this species immediately following T. eunomus.

ADD Rufous-tailed Rock-Thrush Monticola saxatilis, based on one bird present 24-25 June 2021 at Utqiaġvik (K. Hansen, W. Klockner, W. S. Gibson, J. Myles, J. Benningfield, R. Van Buskirk, and others; photos AKCLC). In Muscicapidae, insert Monticola between Saxicola and Oenanthe.

*Ruby-crowned Kinglet has been removed to the genus Corthylio, which is listed preceding Regulus.

AND Chesser et al. (2021) reorganized the linear sequence of a number of Families:

*The family Vireonidae is now listed following Tyrannidae and preceding Laniidae.

*Paridae is now listed following Corvidae and preceding Alaudidae.

*Acrocephalidae and Locustellidae (in that order) are now listed following Alaudidae and preceding Hirundinidae.

*Regulidae and Bombycillidae (in that order) are now listed following Sylviidae and preceding Sittidae.
