654 AZURE WARBLER. 



Found during the summer in Pensylvania, fre- 

 quenting the borders of streams and marshes: it 

 is migratory, and retires very early in the autumn 

 towards the south. It is thus described by the 

 author of American Ornithology : It is in length 

 four inches and a half : the front and upper part 

 of the head are of a fine verditer blue ; the hind 

 head and back of the same colour, but not quite 

 so brilliant : a few lateral streaks of black mark 

 the upper part of the back: wings and tail edged 

 with sky-blue ; the three secondaries next the 

 body edged with white ; and the first and second 

 rows of coverts also tipped with white : tail-coverts 

 large, black, and broadly tipped with blue : lesser 

 wing-coverts black, also broadly tipped with blue, 

 so as to appear nearly wholly of that tint : sides 

 of the breast spotted or streaked with blue : belly, 

 chin, and throat, pure white : the tail is forked ; 

 the five lateral feathers with a white spot on each 

 side, and the two middle slightly marked with the 

 same : from the eye extends a line of dusky blue: 

 from the nostrils, passing over the eye and reach- 

 ing to the ears, is a white stripe : beak dusky 

 above, and light blue beneath : legs and feet light 

 blue."
