VARIATIONS IN HYLOCICHLA USTULATA — BOND 379 



Hylocichia ustulata swainsoni (Tschudi) 



T[urdus] Swainsoni Cabanis Mss. in von Tschudi, Untersuchungen uber die 

 Fauna Peruana, part VI, Ornithologie, pp. 187-188, 1845 [probably Decem- 

 ber]. New name for Merula Wilsonii Swainson, nee T[urdus] Wilsonii 

 Bonaparte. (Carlton House, Saskatchewan River, Saskatchewan, lat. 53°). 



Hylocichia ustulata clarescens Burleigh and Peters, Proc. Biol. Soc. Washington, 

 vol. 61, p. 118, June 16, 1948. (Glenwood, Newfoundland). 



Resembles H. u. almae Oberholser in the nuptial plumage except 

 that the upperparts are decidedly more reddish, less grayish, olive; 

 sides of head and breast are more buffy and spotting of breast paler. 

 In autumn plumage it is separable by the deep reddish olive of its 

 upperparts, distinctly different from the grayish to browmish olive 

 of almae at the same season of the year. Compared with tistulata 

 and oedica, swainsoni may always be separated by the olive suffusion 

 of its upperparts, a characteristic that is lacking in the Pacific coast 

 races, which are much more russet in coloration. 



Breeding range is eastern Alberta (Athabaska River) eastward to 

 Ne"\vfoundland and south in the mountains to West Virginia. Winter 

 range, based on specimens examined, is Mexico (Veracruz, Tabasco, 

 Tres Marias Islands) ; Central America (Costa Rica, Guatemala, 

 Panama); South America (Colombia); West Indies (Bahamas). 

 Recorded in migration in most of the States south of its breeding 

 range. Occasional records in migration from west of the Rocky 

 Mountains (Idaho, Washington, Oregon, British Columbia).
