Adult in hneding-plumarje. General colour above brownish black 

 -with a slight greenish gloss ; forehead, top of the head, and hind- 

 neck black with green gloss ; chin and throat dull sooty-black ; 

 sides of the head and rest of the neck ash-grey, shading into 

 brownish grey at the base of the fore-neck ; sides of the lower back 

 and rump white ; chest, sides, and Hanks washed with shining 

 reddish brown ; breast and belly shining white, more or less mottled 

 with dusky ; thighs, vent, and under tail-coverts dusk)' ; inner 

 webs of outer primaries mostly white, the amount of white gradu- 

 ally increasing so that the inner primarj'-quills are white on the 

 entire inner webs, sometimes white with a dark shaft -stripe, or even 

 pure white in old examjdes ; secondaries white, with a brown band 

 on the margin of the outer web ; under wing-coverts pure white. 

 Iris orange ; bill black, tip whitish ; feet black tinged with 

 greyish (6r. N. Lawrence). Total length about 8'5 inches, culmen 

 from feathers on forehead 0"S-09, wing 3-7-3"85, tarsus 1*15-1'25, 

 middle toe and claw 1-6-1-8. 



Adult in non-breeding plumage. Differs from the above in having 

 the top of the head, neck, and upper parts browner, especially the 

 fore-neck and chest ; chin and throat white. 



The black throat begins to appear early in May, and the summer 

 plumage is generally complete by the beginning of June. 



A quite young bird (Yucatan, Apiil), with the head and neck 

 still partially in down, has the general appearance of the adult in 

 winter plumage, but the top and sides of the head as well as the 

 fore-neck are patterned with black and white much as in the young 

 of P. JiuviatiUs. 



A young male (Presidio, Mexico, Jan. 16) still shows traces of 

 the white markings on the top and sides of the head, but is other- 

 wise very similar to the adult in winter plumage; it may generally, 

 however, be recognized by having the outer webs of all the primary- 

 quills brown.

 America, and South America as far south as Patagonia.
