ADD Kentish Plover Charadrius alexandrinus, based on one bird observed at Shemya Island, Aleutians, on 29 May 2023 (Z. M. Pohlen, photos AKCLC).

ADD Hen Harrier Circus cyaneus, based on a partial specimen salvaged at Attu Island, Aleutians, in Jun 1999 (see Gibson and Byrd 2007). DNA analysis has demonstrated (J. J. Withrow MS in prep.) that this specimen is indeed C. cyaneus and not the Northern Harrier C. hudsonius. These two harriers were split by Chesser et al. (2017).

ADD Eurasian Goshawk Accipiter gentilis, based on two goshawks observed at Shemya Island, Aleutians, one in May and one in Sep 2001, the second of which was entirely off-white, and thus characteristic of Russian Far East subspecies albidus (see Gibson and Byrd 2007). The Eurasian Goshawk and the American Goshawk were split by Chesser et al. (2023).

ADD Eastern Wood-Pewee Contopus virens, based on one bird at Douglas Island, se Alaska, 4-24 Jul 2023 (S. Lewis and many others, incl. T. G. Tobish Jr. and R. L. Scher; photos and audio-recording AKCLC).

Siberian House-Martin Delichon lagopodum—to which species all Alaska records of Delichon are now assigned—was split from Common House-Martin D. urbicum by Chesser et al. (2023).

*Status of Stejneger’s Scoter is changed from casual to rare.

*Status of Red-backed Shrike is changed from accidental to casual (with a third Alaska record at Adak, 2023).

*Status of Song Thrush is changed from accidental to casual (with a third Alaska record at St. Paul, 2023).

*Following Chesser et al. (2023), the English name Rufous-tailed Rock-thrush is to be so spelled because the species (in Muscicapidae, Old World Flycatchers and Chats) has not ever been maintained in the family Turdidae (Thrushes).
