ICTERID.E THE AMERICAN ORIOLES. 323 



"Sp. CHAB. Bill slender; shorter than the head; about equal to the hind toe; its 

 height not quite two fifths the total length. Wing nearly an inch longer than the tail; 

 second quill longest; first a little shorter than the fourth. Tail slightly graduated; the 

 lateral feathers about a quarter of an inch shortest. General color black, with purple 

 reflections; the "wings, under tail-coverts, and hinder part of the belly, glossed with 

 green. In autumn the feathers largely edged with ferruginous or brownish, so as to 

 change the appearance entirely. Spring female dull, opaque plumbeous or ashy black; 

 the wings and tail sometimes with a green lustre. Young like autumnal birds. Length 

 of male, 9.50; wing, 4.75; tail, 4.00. Female smaller." (Hist. _ZV. Am. .) 



It is only during the colder months that this blackbird makes its 

 appearance in Illinois. Perhaps the greater number pass beyond 

 the limits of our State in midwinter, but the writer has seen small 

 flocks in December and January in the bottom lands near Mount 

 Carmel. In early spring they become quite numerous in swampy 

 forests, congregating mostly about the borders of ponds or the 

 banks of streams. Their peculiar squeaking but not unmusical 

 song, which may be heard just before their departure for the North, 

 somewhat resembles that of the Bronzed Grackle (Quiscalus ceneus] 

 but is much less harsh and uttered in a higher key. Occasionally, 

 especially during cold weather, small flocks frequent the barn-yards, 

 for the purpose of gathering the grain which has become scattered 

 about during the feeding of the stock.
