 of incubation, and their note is seldom heard ; and, when it

Description. 



Wings long, much pointed, the second quill longest, the first longer than the 

 third; tail deeply forked; tarsi short; the upper parts ashy-brown, showing darker 

 brown centres of the feathers, this is eminently the case on the top of the head ; 

 the sides of the head and neck, of the breast and body resembling the back, but 

 with the edges of the feathers tinged with gray, leaving a darker central streak ; the 

 chin, throat, narrow line down the middle of the breast and body, abdomen, and 

 lower tail coverts white, or sometimes with a faint tinge of yellow; the lower 

 tail coverts somewhat streaked with brown in the centre; on each side of the rump, 

 generally concealed by the wings, is an elongated bunch of white silky feathers ; 

 the wings and tail very dark brown, the former with the edges of the secondaries 

 and tertials edged with dull-white ; the lower wing coverts and axillaries grayish- 

 brown; the tips of the primaries and tail feathers rather paler; feet and upper 

 mandible black, lower mandible brown; the young of the year similar, but the 

 color duller; feet light-brown. 



Length, seven and fifty one-hundredths inches ; wing, four and thirty-three one- 

 hundredths; tail, three and thirty one-hundredths; tarsus, sixty one-hundredths.
