Version 7.3 – November 2011
Added: Sungrebe (Heliornis fulica)
Placement: after American Coot.
Comments: A female in unworn plumage was detected at Bosque del Apache National Wildlife Refuge, Socorro County, New Mexico, 13–18 November 2008. The bird was discovered and photographed by Sally King with Ernesto Burciaga, and identified and seen by others subsequently (Williams et al. 2009).

Comments: One thought to be in second-basic plumage at Bentsen–Rio Grande Valley State Park, Hidalgo County, Texas, from 21 December 2009 to 20 January 2010. Discovered and photographed by Rick Nirschl and Rick Snider, and observed by hundreds during its month-long stay (Nirschl and Snider 2010).
Added: Solitary Snipe (Gallinago solitaria)
Placement: after Jack Snipe.
Comments: One near Alexai Point, Attu Island, Alaska, on 24 May 2010. Discovered and photographed by a group from Zugunruhe Birding Tours led by John Puschock, then collected by Jack J. Withrow and David W. Sonneborn (Withrow and Sonneborn in preparation) and determined to be an adult male and thought to be of the subspecies G. s. japonica.
Added: Amazon Kingfisher (Chloroceryle amazona)
Placement: after Belted Kingfisher.
Comments: One female along the Rio Grande at Laredo, Webb County, Texas, from 24 January to 3 February 2010. Although the bird was stated in the documentation submitted to the TBRC to be an adult, we are not aware of the characters that were used to age the bird. Discovered and photographed by Robert Epstein and Alan Wormington, and observed by hundreds during its stay (Wormington and Epstein 2010).
Added: Gray-collared Becard (Pachyramphus major)
Placement: after Fork-tailed Flycatcher.
Comments: One second-calendar-year male attaining adult plumage at Cave Creek Canyon, Cochise County, Arizona, on 5 June 2009. Discovered and photographed by Anne Pellegrini, Jillian Johnston, and Ryan Davis, and observed by others later that day (Johnston et al. 2010).
Added: Brown-backed Solitaire (Myadestes occidentalis)
Placement: after Townsend’s Solitaire.
Comments: Two records thought to refer to the same individual. One male at Miller Canyon, Cochise County, Arizona, was discovered and photographed by Benjamin Van Doren, Dave Jasper, and other participants in Camp Chiricahua on 16 July 2009 (Van Doren 2010). Presumably the same individual then traveled 2.7 miles to Ramsey Canyon, Cochise County, Arizona, where it was present 18 July–1 August 2009 (Van Doren 2010). Discovered by Sandy Kunzer and Rick Romea, photographed by Joe Woodley and others, and audio-recorded by Chris Benesh and Dave Stejskal.
Added: Rufous-tailed Robin (Luscinia sibilans)
Placement: after Spotted Flycatcher.
Comments: Two singles. One second-year female at West Massacre Valley, Attu Island, Alaska, on 4 June 2008. Discovered and collected by David Sonneborn and Jack Withrow, the specimen was deposited in the collection at the University of Alaska Museum of the North (UAM 24600), where the identification was confirmed by Daniel Gibson (DeCicco et al. 2009). Another secondyear bird was found four days later, at Northeast Point, St. Paul Island, Alaska, on 8–9 June 2008. Discovered by Lucas DeCicco, and observed and photographed by several others the following day (DeCicco et al. 2009).
Added: Red-legged Thrush (Turdus plumbeus)
Placement: after American Robin.
Comments: One adult at Maritime Hammock Sanctuary, Melbourne Beach, Brevard County, Florida, on 31 May 2010. Discovered and photographed by Marcus Ponce and not observed again (Anderson and Ponce in preparation).
Added: Mexican Whip-poor-will (Caprimulgus arizonae)
Comments: split from Whip-poor-will (Caprimulgus vociferus) by the AOU in its 51st supplement to the check-list. See The Auk 127:726-744, 2010. Caprimulgus vociferus now becomes Eastern Whip-poor-will.
Added: Pacific Wren (Troglodytes pacificus)
Comments: split from Winter Wren (Troglodytes troglodytes) by the AOU in its 51st supplement to the check-list. See The Auk 127:726-744, 2010. The Old World species, thought likely to form four distinct groups, becomes the Eurasian Wren (T. troglodytes) and is extralimital. Of the two newly split North American species, the eastern birds (breeding west to Alberta) remain the Winter Wren (Troglodytes hiemalis) while the species breeding from Alaska to the Pacific region (some breeding sparingly elsewhere in the mountain ranges of western North America) becomes the Pacific Wren (Troglodytes pacificus).
Version 7.1 – November 2009
Added: Swinhoe’s Storm-Petrel (Oceanodroma monorhis)
Placement: after Band-rumped Storm-Petrel.
Comments: One individual, thought to be a juvenile in slightly worn plumage, in the Atlantic Ocean at approximately 65 kilometers east-southeast of Hatteras Inlet, Cape Hatteras, North Carolina on 2 June 2008. Discovered and well-photographed by J. Brian Patteson, Steve N. G. Howell, and others on an organized pelagic trip (Patteson et al. 2009).
Added: White-crested Elaenia (Elaenia albiceps)
Placement: after Greenish Elaenia.
Comments: One calling individual at South Padre Island, Texas on 9–10 February 2008. Found by Daniel Jones and observed, photographed, and audiorecorded by Martin Reid and several others. Identified as an Elaenia by its crest and conspicuous white coronal patch, identified to species by plumage and vocalizations, and identified as the migratory subspecies E. a. chilensis by vocalizations and photographic analysis of plumage and wing formula (Reid and Jones 2009).
Added: Crowned Slaty-Flycatcher (Empidonomus aurantioatrocristatus)
Placement: after Variegated Flycatcher.
Comments: One adult male photographed alive and then collected at Peveto Beach Woods, Cameron Parish, Louisiana on 3 June 2008. The bird was observed alive solely by Paul Conover and Buford Myers. Identified by its size; pale gray face and underparts with a yellowish tinge to the vent and undertail coverts; gray-brown back and wing coverts; blackish lores, eye patch, and auriculars separated from the blackish crown by a gray supercilium; and blackish soft parts. The specimen, prepared as a study skin (LSUMNS #180361 at Louisiana State University Museum of Natural Science), was heavily worn with no molt, and had accumulated heavy fat deposits.
Added: Sinaloa Wren (Thryothorus sinaloa)
Placement: after Canyon Wren.
Comments: One singing individual, presumably an adult, at an elevation of 4,000 feet at Patagonia–Sonoita Creek Preserve, Santa Cruz County, Arizona found on 25 August 2008 and present into August 2009. Discovered and photographed by Matt Brown and Robin Baxter, and observed, photographed, and audio-recorded by many others (no formal paper published through August 2009). Distinguished from other medium-sized wrens by its rich, varied, warbling song; moderate black streaking on the auriculars and neck; brown back contrasting with rusty tail; and plain underparts with gray breast. Distinguished from the similar Happy Wren (T. felix), a potential stray to the ABA Area from northwestern Mexico, by voice, barring on wing coverts, and pale (rather than buffy) underparts (Howell and Webb 1995).
Removed: Caribbean Elaenia (Elaenia martinica)
Comments: The ABA Checklist Committee accepted Caribbean Elaenia in 1985, but admitted that the identification represented a “borderline case.” Although the elaenia vocalized frequently, its calls were not audio-recorded. Because the Florida Ornithological Society Records Committee recently downgraded this record to “Elaenia species,” the ABA Checklist Committee also reevaluated the record and decided that the lack of audio–recordings left doubt as to its specific identity. Ironically, this bird may have been a White–crested Elaenia, which was added to the ABA Checklist based on a recent Texas record.
Version 7.0 – November 2008
Added: Graylag Goose (Anser anser)
Placement: after Pink-footed Goose.
Comments: one bird was found alive on a stationary ship in the Atlantic Ocean off the coasts of Newfoundland and Labrador from spring, 2005.

Added: Townsend’s Shearwater (Puffinus auricularis)
Placement: after Manx Shearwater.
Comments: an individual from near Del Mar, California, was caught and taken to be rehabilitated in August 2007, where measurements and photographs were used for positive identification.
Added: Tristram’s Storm-Petrel (Oceanodroma tristrami)
Placement: after Black Storm-Petrel.
Comments: an individual caught during night mist-netting from Southeast Farallon Island, California, in April, 2006. Proper identification resulted after careful measurements were taken, in addition to comparisons with museum specimens of congeners.
Added: Brown Hawk-Owl (Ninox scutulata)
Placement: after Northern Saw-whet Owl.
Comments: two birds, the first from St. Paul Island, Pribilof Islands, Alaska, from late August – early September 2007 was well-photographed and easy to identify.
Added: Loggerhead Kingbird (Tyrannus caudifasciatus)
Placement: after Gray Kingbird.
Comments: two birds, the first from Fort Zachary Taylor State Park, Key West, Florida, in March 2007 was added to the Checklist shortly after the species had been removed from the List due to uncertain identification difficulties.
Added: Sedge Warbler (Acrocephalus schoenobaenus)
Placement: after Lanceolated Warbler.
Comments: an individual from Gambell, St. Lawrence Island, Alaska, in September 2007. Photographs ruled out look-alike congeners.
Added: Song Thrush (Turdus philomelos)
Placement: after Redwing.
Comments: an individual found at a private residence at Saint-Fulgence, Quebec, Canada, in November 2006 was photographed and identified.

Added: European Turtle-Dove (Streptopelia turtur)
Placement: placed after Oriental Turtle-Dove.
Comments: three records of singles: one photographed at Lower Matecumbe Key, Monroe County, Florida, 9-11 April 1990, a record that was relegated to the CLC’s short-lived “Origin Uncertain” list; one photographed inhand at St. Pierre, St. Pierre Island, France, sometime between 15-20 May 2001; and one thought to be of the nominate race that was run over by a vehicle at Tuckernuck Island, Nantucket County, Massachusetts, on 19 July 2001.
Added: Pallas’s Leaf-Warbler (Phylloscopus proregulus)
Placement: provisionally placed after Yellow-browed Warbler.
Comments: one of the nominate race at the “Circular Boneyard” at Gambell, St. Lawrence Island, Alaska, on 25-26 September 2006 was discovered and photographed by Paul Lehman and Gary Rosenberg.
Added: Tundra Bean-Goose (Anser serrirostris)
Comments: split from Bean Goose (Anser fabalis) by the AOU in its 48th supplement to the check-list. See The Auk 124(3):1109-1115, 2007. Anser fabalis now becomes Taiga Bean-Goose.

Removed: Yellow-chevroned Parakeet (Brotogeris chiriri)
Comments: this species was added to the Checklist in 2002 based on the occurrence of naturalized populations in California and Florida, following the “splitting” of the Canary-winged Parakeet (B. versicolurus) into Whitewinged Parakeet (B. versicolurus) and Yellow-chevroned Parakeet. However, the Yellow-chevroned Parakeet has never been accepted by the CBRC or FOSRC.
