142 DWIGHT 



Above, dull brownish olive-green, greener than in previous plumage, the feathers 

 darker centrally, producing a streaked effect chiefly on the pileum ; upper 

 tail coverts dark cinnamon-rufous ; wing covert edgings, including two wing- 

 bands, grayish or yellowish-buff. Below, bright lemon-yellow, brighter than 

 in previous dress, throat lores and auriculars ashy-gray. 



4. First Nuptial Plumage acquired by wear, which is quite 

 obvious, the edgings of the wing coverts and tertiaries fading to 

 a dingy white and the whole plumage becoming paler. 



5. Adult Winter Plumage acquired by a complete post- 

 nuptial moult beginning early in August and completed before 

 the birds move south in September. Practically indistinguish- 

 able from first winter, the colors often richer. 



6. Adult Nuptial Plumage acquired by wear, as in the 

 young bird. 



Female. — Moults and plumages correspond to those of the 

 male, the colors often duller. 



Sayornis phoebe (Lath.). Phcebe 



1. Natal Down. Mouse-gray 



2. Juvenal Plumage acquired by a complete postnatal moult 



Above, including sides of head and neck, wings and tail, olive-brown, distinctly 

 clove-brown on pileum and nape. Below, yellow-tinged white, breast, throat 

 and sides of chin, brownish olive-gray. Greater and median coverts (?'. e., 

 wing bands) and rectrices tipped with cinnamon-rufous, secondaries and ter- 

 tiaries, edged with brownish or yellowish white Bill and feet raw umber- 

 brown, black when older. 



3. First Winter Plumage acquired by a partial postju venal 

 moult beginning about mid-August which involves the body 

 plumage, wing coverts and tertiaries, but not the rest of the 

 wings nor the tail. Birds in ju venal dress occur as late as the 

 end of September. After moulting they are yellower below 

 with pale grayish wing bands and practically indistinguishable 

 from adults. 



Above, olive-brown, greener than in previous plumage, pileum nearly black, the 

 olive of the upper parts encroaching on sides of chin, throat and flanks. Be- 

 low, primrose-yellow, a grayish pectoral band very faintly indicated. The wing 

 coverts are narrowly edged with yellowish white. 



4. First Nuptial Plumage acquired by wear, the brown of 

 the upper parts and the yellow below becoming paler. During
