PASSERINE BIRDS OF NEW YORK 251 



Compsothypis americana (Linn.). PARULA WARBLER 



1. NATAL DOWN. Smoke-gray. 



2. JUVENAL PLUMAGE acquired by a complete postnatal moult. 



Above, including sides of head, brownish olive-gray ; indistinct superciliary stripe and 

 orbital ring white, yellow tinged ; faint dusky transocular streak. Wings clove- 

 brown, the edgings chiefly olive-green, bluish on the primaries and their coverts. 

 Two wing bands tipping coverts, white. Tail clove-brown edged with ashy 

 blue the outer rectrices with subterminal white blotches on their inner webs. 

 Bill and feet pinkish buff, the former becoming dusky, the latter deep sepia- 

 brown with age. 



3. FIRST WINTER PLUMAGE acquired by a partial postjuvenal 

 moult, beginning the middle of July, which involves the body 

 plumage and the wing coverts but not the rest of the wings nor 

 the tail. 



Unlike the previous plumage. Above, including sides of head, bluish plumbeous 

 gray veiled by olive-green edgings, the back chestnut-tinged veiled by olive- 

 yellow. Below, canary-yellow on chin and throat, veiling a pectoral band of 

 pale chestnut, which is dusky on the jugulum and invaded by the gray of the 

 sides of the neck. The abdomen and crissum, white, veiled slightly with edg- 

 ings of canary-yellow, the sides and flanks faintly washed with cinereous gray 

 and pale chestnut. The wing coverts are bluish plumbeous gray, broadly 

 tipped with white yellow-tinged, forming two wing bands. Indistinct super- 

 ciliary line and large suborbital spot white. A dusky transocular streak. 



Young and old become practically indistinguishable in many 

 cases, the young birds usually duller and especially lacking in 

 chestnut on the chin. 



4. FIRST NUPTIAL PLUMAGE acquired by a partial prenuptial 

 moult which involves chiefly the head, chin and throat, but not 

 the rest of the body plumage, the wings nor the tail. The ashy 

 blue crown feathers faintly dusky centrally, the blackish ones 

 of the sides of the head with a white spot above and below the 

 eye and the yellow or chestnut-tinged chin feathers as far as the 

 pectoral band or farther are assumed by moult. W 7 ear brings 

 the back into contrast with the nape and whitens the lower parts. 

 The wings and tail are browner and more worn than in the adult, 

 especially the primary coverts. 



5. ADULT WINTER PLUMAGE acquired by a complete postnuptial 

 moult in July. Practically indistinguishable from first winter
