As of January 2016 the total number of species known to have occurred in Alaska is now 510. The five added to the Alaska list in 2015 were:Red-footed Booby Sula sula — based on a bird photographed on 10 September 2015 off East Chugach I., Gulf of Alaska; and a sight report of one on 25 August 2015 southeast of the town of Kodiak, Kodiak I. [Accidental in s-c Alaska];
Blyth’s Reed Warbler Acrocephalus dumetorum — based on a bird photographed during 18-21 September 2015 at Gambell, St. Lawrence I. [Accidental in w Alaska];
Yellow-throated Warbler Setophaga dominica — based on a bird photographed during 22-24 September 2015 at Gustavus [Accidental in se Alaska];
Hooded Oriole Icterus cucullatus — based on an adult male photographed during 19-22 September 2015 at Juneau [Accidental in se Alaska]; and
Pallas’s Rosefinch Carpodacus roseus — based on an immature male photographed during 21-24 September 2015 at St. Paul I., Pribilofs [Accidental in sw Alaska].
Other changes to the Checklist of Alaska Birds include changes in status for Cook’s Petrel (Accidental to Casual), Flesh-footed Shearwater (Casual to Rare), Manx Shearwater (Casual to Rare), Brown Booby (Accidental to Casual), European Golden-Plover (Accidental to Casual), Yellow-bellied Sapsucker (Casual to Rare), and Palm Warbler (Casual to Rare). The English name of the family Muscicapidae has been recast to read Old World Flycatchers and Chats. And the 56th Supplement to the AOU Check-list of North American Birds (2015) accepted evidence that the American Tree Sparrow is sufficiently distinct from the other members of the genus Spizella to warrant its own genus, and it is now Spizelloides arborea.
