Adult male. Similar to ££. alexandrina, but easily distinguished 

 by its white lores, which entirely want the blackish or dusky streak 

 between the base of the bill and the eye ; the black forehead and 

 the black patch on the sides of the chest, as well as the black ear- 

 streak, are all well developed, but the rufous colour of the head 

 is never so strongly pronounced as in 2E. alexandrina, and it 

 disappears rapidly after the bird has arrived at its breeding- 

 quarters, so that the bead is ashy brown like the back, shaded with 

 hoary white. Total length about 6*5 inches, culmen 0'7, wing 4 - 15, 

 tail 1*7, tarsus 0-95, middle toe and claw 0-7. 



Adult female. Similarly coloured to the male. Total length 

 about 6-5 inches, culmon 0"65, wing 4-3, tail 1*8, tarsus 0"9. 



Adults in winter plumage. Differs from the summer plumage in 

 entirely wanting the black on the fore part of the crown, ear-coverts 

 or sides of the chest, these parts being brown like the rest of the 

 upper surface ; forehead and eyebrow conspicuously white. There 

 is a slight indication of a white collar round the hind-neck. 



Young. Itesembles the winter plumage of the adult, but has the 

 upper surface varied with pale edges to the feathers, producing a 

 somewhat scalloped appearance, the margins to most of the dorsal 

 feathers, the inner secondaries, and tail-feathers being pale sandy. 



Hub. Western North America, throughout Central America and 

 Western South America to Peru and Chili. ? Cuba.
