BIRDING • NOVEMBER 2010 30 T his is the 21st published report of the ABA Checklist Committee (hereafter, ABA CLC), covering the period August 2009–Septem- ber 2010. Since our previous report (Pranty et al. 2009), Heinl, Kratter, and Mactavish cycled off the committee after having served two consecutive four-year terms. Those members were replaced by Gibson, Iliff, and Pittaway. Gibson returns to the ABA CLC after a 19-year absence, while Iliff and Pittaway are new to the committee. Pranty was re- elected to serve as chair for a fifth year, and Lock- wood was selected to assist Pranty as needed. During the preceding 14 months, the ABA CLC finalized votes on seven species, of which all were accepted and added to the ABA Checklist. Those records come from Alaska, Arizona, Texas (two species each), and Florida (one species). Addition- ally, taxonomic changes made by the Committee on Classification and Nomenclature (North and Mid- dle America) of the American Ornithologists’ Union (hereafter, AOU) resulted in the addition of two “new” species as the result of taxonomic “splitting” (Chesser et al. 2010). The number of accepted species on the ABA Checklist is increased to 969.

This is the 21st published report of the ABA

Checklist Committee (hereafter, ABA CLC),

covering the period August 2009–Septem-

ber 2010. Since our previous report (Pranty et al.

2009), Heinl, Kratter, and Mactavish cycled off the

committee after having served two consecutive

four-year terms. Those members were replaced by

Gibson, Iliff, and Pittaway. Gibson returns to the

ABA CLC after a 19-year absence, while Iliff and

Pittaway are new to the committee. Pranty was re-

elected to serve as chair for a fifth year, and Lock-

wood was selected to assist Pranty as needed.

During the preceding 14 months, the ABA CLCfinalized votes on seven species, of which all wereaccepted and added to the ABA Checklist. Thoserecords come from Alaska, Arizona, Texas (twospecies each), and Florida (one species). Addition-ally, taxonomic changes made by the Committee onClassification and Nomenclature (North and Mid-dle America) of the American Ornithologists’ Union(hereafter, AOU) resulted in the addition of two“new” species as the result of taxonomic “splitting”(Chesser et al. 2010). The number of acceptedspecies on the ABA Checklist is increased to 969. An-cillary numbers are provided for all additions toallow for their proper placement on the seventh edi-tion of the ABA Checklist (Pranty et al. 2008).

New Species Accepted–––––––––––––––––––––––––––––––––––––––––––––––––––––Bare-throated Tiger-Heron (Tigrisoma mexi-canum). ABA CLC Record #2010-02. One thoughtto be in second-basic plumage at Bentsen–RioGrande Valley State Park, Hidalgo County, Texas,from 21 December 2009 to 20 January 2010. Dis-

covered and photographed by RickNirschl and Rick Snider, and observed byhundreds during its month-long stay(Nirschl and Snider 2010). Distinguishedfrom the extralimital Rufescent Tiger-Heron (T. lineatum) and Fasciated Tiger-Heron (T. fasciatum) by its unfeatheredgreenish-yellow throat, gray legs andfeet, and black crown contrastingwith a gray face. Bare-throatedTiger-Heron is not known to bekept in captivity (ISIS 2010).Accepted unanimously by theTexas Bird Records Committee(TBRC) and by the ABA CLC.The Bare-throated Tiger-Heron

is resident from northern Mexico(southern Sonora and southern Tamauli-pas, about 240 kilometers south ofBrownsville) to Panama and northwesternColombia (Howell and Webb 1995, AOU1998). A small, isolated population wasdiscovered in Peru in 1999 (Nirschl andSnider 2010).Bare-throated Tiger-Heron (173.1) is

placed on the ABA Checklist as a Code 5species. Following AOU, itis placed between Least Bit-tern (173) and Great BlueHeron (174).

Solitary Snipe (Gallinagosolitaria). ABA CLC Record#2010-06. One near AlexaiPoint, Attu Island, Alaska,on 24 May 2010. Discov-ered and photographed bya group from ZugunruheBirding Tours led by JohnPuschock, then collected byJack J. Withrow and DavidW. Sonneborn (Withrowand Sonneborn in prepara-tion) and determined to bean adult male and thoughtto be of the subspeciesG. s. japonica. Distinguishedfrom other snipes by meas-

urement data, the “cold” plumage lackingbuffy tones, white face and belly, white“braces” on the mantle, and extensive darkbarring on the breast and flanks. Acceptedunanimously by the Alaska Checklist Com-mittee (AKCLC) and by the ABA CLC. Aprevious report of a Solitary Snipe de-

scribed and distantly photographed atSt. Paul Island, Alaska, on 10 Sep-tember 2008 (Bieber andSchuette 2009) was relegatedby the AKCLC to its Unsub-stantiated List because theidentification was regarded asprobably correct but not satis-

factorily substantiated by a photo-graph or specimen.

The Solitary Snipe breeds in mountainsfrom south of Lake Baikal and northwest-ern Mongolia south and west to north-western China and in much of theHimalayas from western Kashmir east atleast to Sikkim and probably southernTibet (Vaurie 1965), and has recentlybeen detected breeding as far east as thewestern Chukotski Peninsula (Tomkovich

2008). It is mainly an alti-tudinal migrant, but thereis some longer migration aswell. The species wintersfrom northeastern Iran andPakistan to eastern China,Korea, and Japan (Haymanet al. 1986, Tomkovich2008). Reports of moredistant vagrant SolitarySnipes from eastern Indiaand from Hong Kong citedby Bieber and Schuette(2009) were questioned byRasmussen and Anderton(2005) and not acceptedby Carey et al. (2001), re-spectively.Solitary Snipe (337.1) is

placed on the ABA Checklistas a Code 5 species. Fol-lowing Dickinson (2003),

Amazon Kingfisher (Chloroceryle amazona). ABA CLC

Record #2010-03. One female along the Rio Grande atLaredo, Webb County, Texas, from 24 January to 3 February

2010. Although the bird was stated in thedocumentation submitted to the TBRC to bean adult, we are not aware of the charactersthat were used to age the bird. Discovered andphotographed by Robert Epstein and AlanWormington, and observed by hundreds dur-ing its stay (Wormington and Epstein 2010).Distinguished from Green Kingfisher by itslarger size, heavy bill, and minimal whitespotting on the wings. Accepted unanimouslyby the TBRC and by the ABA CLC. A report oftwo Amazon Kingfishers near Rangerville,Cameron County, Texas, 21 October–23 No-vember 1996 (Lasley et al. 1997) was rejectedby the TBRC (Lockwood 1998).The Amazon Kingfisher is resident from

northern Mexico (southern Sinaloa andsouthern Tamaulipas) to northern Argentinaand Uruguay; it ranges to northern Sinaloaduring the winter (AOU 1998).Amazon Kingfisher (526.1) is placed on the

ABA Checklist as a Code 5 species. FollowingAOU, it is placed between Belted Kingfisher(526) and Green Kingfisher (527).

Gray-collared Becard (Pachyramphus major). ABA CLCRecord #2010-05. One second-calendar-year male attainingadult plumage at Cave Creek Canyon, Cochise County, Ari-zona, on 5 June 2009. Discovered and photographed byAnne Pellegrini, Jillian Johnston, and Ryan Davis, and ob-

New ABA CLC MembersDaniel D. Gibson has studied the status, distribution, abundance, and geographic variation of Alaska’s birds for 45 years. Long associ-ated with the University of Alaska Museum at Fairbanks, he recently retired as the bird collection manager and now continues as a re-search associate. He has authored numerous publications, most recently Birds of the Aleutian Islands, Alaska with G. Vernon Byrd. Gibsonhas been a member of the Alaska Checklist Committee since its inception.

Marshall J. Iliff is a project leader for eBird. Formerly a guide for Victor Emanuel Nature Tours, he has actively birded throughout the ABAArea for more than 20 years. Iliff is a past regional editor for the Mid-Atlantic and Baja California regions for North American Birds, and hasauthored or coauthored a number of articles and book chapters. He has long had a special interest in rare and vagrant birds. Iliff has servedon records committees in Maryland and California, and is the current chairman of the Massachusetts Avian Records Committee.

Ron Pittaway is a life member of both the ABA and Ontario Field Ornithologists. He served on the Ontario Bird Records Committeefor 12 years during the period 1984–2003, including three years as chairman and one as secretary. He was coeditor of the provincialjournal Ontario Birds from 1991 to 2006. Pittaway has authored more than 130 articles about birds, focusing on field identification, sub-species, morphs, molts and plumages, and conservation.

served by others later thatday (Johnston et al. 2010).Distinguished from otherbecards by its combinationof brown cap and mantle,broad white collar (gray inadults), black wings withbroad white feather edg-ings, and very pale under-parts. Determined to be ofthe western subspecies P. m.uropygialis by the pale col-oration of the nape and un-derparts, along with thebrown cap bordered byblack. Accepted unani-mously (after second-round voting) by the Arizona BirdCommittee (ABC), and unanimously by the ABA CLC. Thenoticeable abrasion to the remiges and the molt in the rec-trices caused minor concern among some ABC and ABACLC members that the bird may have been kept captive.The Gray-collared Becard is resident from northwestern

Mexico (eastern Sonora) to El Salvador and central Nica-ragua, and it is a pronounced altitudinal migrant (Howelland Webb 1995, AOU 1998, Johnston et al. 2010). A reportfrom El Tabacote, Sonora (256 kilometers south of Arizona)on 17 March 1984 (Monson 1986) previously suggested thisspecies’ potential to reach the ABA Area.Gray-collared Becard (597.1) is placed on the ABA Check-

list as a Code 5 species. Following AOU, it is placed betweenFork-tailed Flycatcher (597) and Rose-throated Becard(598).

Brown-backed Solitaire (Myadestesoccidentalis). ABA CLC Record#2010-04. Two records thought torefer to the same individual. Onemale at Miller Canyon, CochiseCounty, Arizona, was discoveredand photographed by Benjamin VanDoren, Dave Jasper, and other partic-ipants in Camp Chiricahua on 16July 2009 (Van Doren 2010). Pre-sumably the same individual thentraveled 2.7 miles to Ramsey Canyon,Cochise County, Arizona, where itwas present 18 July–1 August 2009(Van Doren 2010). Discovered bySandy Kunzer and Rick Romea, pho-tographed by Joe Woodley and oth-

ers, and audio-recorded by Chris Beneshand Dave Stejskal. Distinguished from otherMyadestes solitaires by its brown upperpartsand unique song. Accepted 7–1 in second-round voting by the ABC, with the dissentingvote concerning provenance; accepted unani-mously by the ABA CLC. A previous ABA Areaphotographic record, at Madera Canyon, PimaCounty, Arizona, on 4 October 1996 was re-jected by the ABC on the grounds of uncertainprovenance (Rosenberg et al. 2007). However,the ABC is reevaluating this record (G. Rosen-berg, personal communication). Brown-backed Solitaire is frequently found caged inMexico because of its striking song, which issung year round. Nonetheless, the ABA CLC

was satisfied that the records pertained to a wild individualdue to their rather remote locations and the seasonality of theoccurrences.The Brown-backed Solitaire is resident from northern

Mexico (southern Sonora and Nuevo Leon, and from thecentral interior) to northern El Salvador and central Hon-duras (Howell and Webb 1995, AOU 1998), generally re-maining in highland breeding areas. More recently, breedingwas observed in the Sierra Huachinera, Sonora, in 2006, 130kilometers south of the U.S. border and 192 kilometers fromMiller Canyon (Van Doren 2010). There is one report fromBelize (Howell and Webb 1995).Brown-backed Solitaire (718.1) is placed on the ABA

Checklist as a Code 5 species. Following AOU, it is placedbetween Townsend’s Solitaire (718) and Orange-billed

Nightingale-Thrush (719).

Rufous-tailed Robin (Lus-cinia sibilans). ABA CLCRecord #2009-04. Two sin-gles. One second-year femaleat West Massacre Valley, AttuIsland, Alaska, on 4 June2008. Discovered and col-lected by David Sonnebornand Jack Withrow, the speci-men was deposited in the col-lection at the University ofAlaska Museum of the North(UAM 24600), where theidentification was confirmedby Daniel Gibson (DeCicco etal. 2009). Another second-year bird was found four days

later, at Northeast Point, St. Paul Island, Alaska, on 8–9 June2008. Discovered by Lucas DeCicco, and observed and pho-tographed by several others the following day (DeCicco et al.2009). Distinguished from other thrushes by the combina-tion of whitish underparts with scaly gray breast and flanks,and brown upperparts contrasting with the rusty tail and up-pertail coverts. Both records were accepted unanimously bythe AKCLC and the ABA CLC. An earlier report (ABA CLCRecord #2002-05), relegated by the AKCLC to the AlaskaUnsubstantiated List and not accepted by the ABA CLC (Rob-bins et al. 2003), was a bird distantly photographed at AttuIsland on 4 June 2000 (DeCicco et al. 2009).The Rufous-tailed Robin breeds in eastern Russia, north-

eastern China, and northern Korea. It winters mostly insouthern China, with some also in Vietnam, Laos, and cen-tral-eastern Thailand. It is a rare and irregular migrant toJapan (Brazil 1991, DeCicco et al. 2009).Rufous-tailed Robin (708.1) is placed on the ABA Check-

list as a Code 5 species. Following AOU, it is placed first inLuscinia, thus appearing between Spotted Flycatcher (708)and Siberian Rubythroat (709). The species is widely con-sidered to be monotypic (e.g., Dickinson 2003).

Red-legged Thrush (Turdus plumbeus). ABA CLC Record#2010-07. One adult at MaritimeHammock Sanctuary, MelbourneBeach, Brevard County, Florida, on31 May 2010. Discovered and pho-tographed by Marcus Ponce andnot observed again (Anderson andPonce in preparation). Distin-guished from other thrushes by itsuniform slate-gray body with nobuffy tones on the belly, white chin,black throat, red orbital ring, andorange-red legs and feet. Morespecifically, the unicolored under-parts and restricted white on theface identify the individual as be-longing to the nominate subspeciesT. p. plumbeus, which is restricted tothe northern Bahamas (Clement2000, Dickinson 2003) and is thesubspecies most likely to reacheast-central Florida. Red-leggedThrushes are not known to be keptcaptive (ISIS 2010, Anderson andPonce in preparation). Accepted

unanimously by the Florida Ornithological Society RecordsCommittee and by the ABA CLC.

The Red-legged Thrush is resident inthe northern Bahamas, Cuba, the Isle ofYouth, the Cayman Islands, Hispaniola,Puerto Rico, and Dominica (Raffaele et al.1998, Hallett 2006). It is absent from Ja-maica and from the Lesser Antilles otherthan Dominica.Red-legged Thrush (736.1) is placed on

the ABA Checklist as a Code 5 species. Fol-lowing AOU, it is placed last in Turdus,thus falling between American Robin(736) and Varied Thrush (737).

Votes in Progress––––––––––––––––––––––––––––––––––––––––––The ABA CLC voted on one other speciesduring the period but did not reach con-sensus. Members did not agree on theidentity of a putative Solander’s Petrel(Pterodroma solandri) photographed ap-proximately 59 kilometers west-southwestof Tofino, British Columbia, on 6 October2009. The ABA CLC voted 5–3 on therecord, which will undergo external re-

Except for last year’s Sinaloa Wrens, no species had been added tothe ABA Checklist from Arizona since Blue Mockingbird in 1996—based on records in 1991–1992 and 1995. As if to compensate, twospecies are added to the ABA Checklist from that state in this report.The first of these, Gray-collared Becard, was a one-day wonder. Thespecies ranges north to eastern Sonora. Cave Creek Canyon, CochiseCounty, Arizona; 5 June 2009. Photo by © Jillian Johnston.

view and then a second round ofvoting. There is currently no BritishColumbia bird records committeeto assist the ABA CLC with reviewof this record.Two species mentioned in our

previous report (Pranty et al. 2009)are still under consideration. First,with regard to reports of Fea’s Pe-trels photographed off North Car-olina, the ABA CLC was awaitingpublication of a major paper (Shir-ihai et al. 2010) that discusses theidentification and distribution ofFea’s, “Desertas,” and Zino’s petrelsbefore voting to add Fea’s Petrel tothe ABA Checklist. Second, with re-gard to a putative Gray Gull pho-tographed in Louisiana in 1987, theABA CLC has decided that addi-tional evidence purported to existwill likely never be located. This record was not accepted bythe Louisiana Bird Records Committee (Dittmann andCardiff 2003), because the bird may have been a melanisticLaughing Gull.

Votes Anticipated–––––––––––––––––––––––––––––––––––––––––––––––––––Within the next 12 months, the ABA CLC will voteon the following records if they pass local-commit-tee review: Common Shelduck (Tadorna tadorna)in Massachusetts (a recent record from Newfound-land will not be reviewed because of questions ofprovenance), Sungrebe (Heliornis fulica) in NewMexico (Williams et al. 2009), Cuban Black-Hawk(Buteogallus gundlachii) in Georgia, PurpleSwamphen (Porphyrio porphyrio) in Florida (estab-lished exotic), and Rosy-faced Lovebird (Agapornisroseicollis) in Arizona (established exotic). Addi-tionally, the ABA CLC may re-review the evidenceof potential establishment of Black-hooded Para-keets (Nandayus nenday) in Florida; it has been fiveyears since the previous ABA CLC review.Recent ABA CLC reports had indicated that the

committee would eventually review on a formalbasis recent claims of persistence of Ivory-billedWoodpeckers in the southern U.S. (e.g., Fitzpatrick

et al. 2005, Hill et al. 2006). In discussing the matter recently,members of the ABA CLC agreed to maintain the status quo(as per the seventh edition of the ABA Checklist), whereby theIvory-billed Woodpecker is listed as a Code 6 species, mean-

ing that it is probably or definitely extinct. Thisstatus will be maintained unless a record is ob-tained with less problematic evidence than hasbeen put forth in recent years.

AOU Taxonomic and NomenclatorialChanges Affecting the ABA Checklist––––––––––––––––––––––––––––––––––––––––––––––The 51st supplement to the AOU’s Check-listof North American Birds (Chesser et al. 2010)was published in August 2010, and allchanges affecting avian taxonomy andnomenclature within the ABA Area are auto-matically accepted by the ABA CLC. Manychanges made by the AOU affect the ABAChecklist, especially in the sequence of somepasserine groups (e.g., moving the longspursto precede the wood-warblers). The changesin sequence are so dramatic that the number-ing sequence of the seventh edition of the ABAChecklist requires rather substantial changes,more so than are included here. The 51st sup-plement to the AOU Check-list results in thefollowing changes to the seventh edition ofthe ABA Checklist:

• Black Scoter (53) is split into two species, onefound in the western Palearctic and the other inthe eastern Palearctic and the New World. TheEnglish names of both species published in the51st supplement—American Scoter and BlackScoter, respectively—are erroneous and havebeen corrected in the September/October 2010Auk (A. Kratter, personal communication). Thecorrected English names are Black Scoter(Melanitta americana) for “our” species and Com-mon Scoter (M. nigra) for the western Palearcticspecies. Although currently extralimital, Com-mon Scoter breeds in Iceland and occurs casu-ally in Greenland (Boertmann 1994)—whereinterestingly it is the only taxon recorded—so itseems a possible stray to the ABA Area.

• Greater Shearwater (128) becomes Great Shear-water.

• Whip-poor-will (488) is split into an east-ern North American species and a north-ern Middle American species: EasternWhip-poor-will (Caprimulgus vociferus;488) and Mexican Whip-poor-will (C. ari-zonae; 488.1).

• Crowned Slaty-Flycatcher (587.1) ischanged to Crowned Slaty Flycatcher,without a hyphen.

• The genus of Brown Jay (623) is changedfrom Cyanocorax to Psilorhinus.

• Winter Wren (681) is split into threespecies. The Old World species, thoughtlikely to form four distinct groups, be-comes the Eurasian Wren (T. troglodytes)and is extralimital. Of the two newly splitNorth American species, the eastern birds(breeding west to Alberta) remain theWinter Wren (681.1) while the speciesbreeding from Alaska to the Pacific region(some breeding sparingly elsewhere in themountain ranges of western North Amer-ica) becomes the Pacific Wren (T. pacificus;681).

This putativeSolander’s Petreloff British Columbiawas first thought tobe a Murphy’s Petrel,and it may yet bedetermined to bethat species. BritishColumbia is one ofvery few states orprovinces to lack alocal bird recordscommittee, and thelack of local reviewprior to its examina-tion by the ABA CLCresulted in a mixedvote. The record willnow undergo exter-nal review before thesecond round of ABACLC voting. ClayoquotCanyon, off Tofino,British Columbia; 6October 2009. Photoby © Sharon Toochin.

Populations of exotic birds often appear to fluctuate greatly, which prevents manyexotic species from being added to the ABA Checklist. One species that seems destinedfor ratification is the Purple Swamphen in Florida, which was discovered aroundDecember 1996. A state-sponsored eradication attempt resulted in the shooting ofmore than 3,100 swamphens between October 2006 and March 2009. The effort wascancelled in April 2009 because an additional 2,000+ swamphens were thought to havesurvived, they are prolific breeders, and they already occupied millions of acres of wet-lands. In November 2009, a Purple Swamphen photographed at Glennville, Georgia,had probably dispersed from the Florida population.

• Rufous-crowned Sparrow (848) is retainedwithin Aimophila, which also includes twoMiddle American species, but the genus isnow placed in between the Pipilo andMelozone towhees.

• The sequence of the Peucaea sparrows fol-lowing Rufous-winged Sparrow ischanged to Botteri’s (845), Cassin’s (846),and Bachman’s (847) sparrows.

• The genus of Five-striped Sparrow (849) reverts fromAimophila to Amphispiza, and the species is moved to pre-cede Black-throated Sparrow (859).

• The longspurs and Plectrophenax buntings are moved to fol-low Olive Warbler (769), and the sequence is changed toLapland, Chestnut-collared, Smith’s, and McCown’slongspurs, and Snow and McKay’s buntings.

• The genus of McCown’s Longspur (formerly 880) revertsfrom Calcarius to Rhynchophanes.

Another exotic that may be added to the ABA Checklist is the Rosy-facedLovebird (known as Peach-faced Lovebird in North American field guides).Although breeding at Phoenix, Arizona, was first noted in 1987, information onpopulation size and status had been lacking. On the morning of 25 February 2010,a lovebird survey was undertaken by 60 observers throughout the greater Phoenixarea. More than 900 birds were found, and thousands of others are thought to havebeen overlooked (K. Radamaker, personal communication). A publication of thesurvey results is in preparation.

A complex of species formerly known as the Winter Wren is wide-spread in the holarctic region. In 2010, the AOU split the complexinto three species, one of these (Eurasian Wren) being restricted tothe Old World. The two New World species are Winter Wren, whichbreeds from Alberta to the Atlantic Ocean, and Pacific Wren, pic-tured here, which breeds from Alaska to California and sparinglyelsewhere in western mountain ranges.

It had long been suspected that two non-overlapping breedingpopulations of whip-poor-wills, with different songs, morphology,and egg color, represented separate species. A paper published in2010 proved that the two populations show strong genetic differ-ences. Those differences, combined with the above characters, ledthe AOU to separate the populations into separate species. The pop-ulation formerly treated as the nominate eastern subspecies is nowknown as Eastern Whip-poor-will. The population formerly treatedas the arizonae subspecies, pictured here, which occurs in the south-west, is known along with four Middle and South American sub-species (Dickinson 2003) as Mexican Whip-poor-will.
