BLACKBIRDS, ORIOLES, ETC. 269 



This bird is found during the migratious in small flocks oh fresh- 

 water meadows or about open, bushy swamps, feeding on the ground 

 in alder thickets or along the edges of swampy woods. It resembles, 

 more or less, the Red-winged Blackbird in size, flight, and notes, but 

 unlike this species, with which it sometimes associates, it is compara- 

 tively quiet and retiring. Only at times, in the spring, do we find the 

 flocks musical centers, whence issues a confused medley of whistles, 

 sweeter and higher-pitched than the best efforts of the Redwings. 

 Little is known of this Blackbird in its northern home. It gathers 

 into flocks early in the summer, and the most frequently heard note 

 is a " cluch," not in the least characteristic. Its quiet demeanor, pale- 

 yellow eye, and uniform color are its chief distinguishing characters 

 in the field, where it may be mistaken for the Bronzed or Purple 

 Grackle. The gray female is unlike the streaked female Redwing.

 Brewer's Blackbird {510. ScolecopMg-us cyanocephalus) inhabits west- 

 ern North America, and is of casual occurrence as far east as Illinois and 

 Louisiana, and has been once recorded from South Carolina. It may be dis- 

 tinguished from i^ carolinus by its deep violet-purple head and the compara- 

 tive absence of rusty tips to the feathers.

Bemnarks. — Intermediates between this and the Bronzed Grackle are found 

 where their ranges adjoin, but typical quiscula always has iridescent bars on 

 the feathers of the back, rump, and belly, while in mneus these bars are want- 

 ing. (On the relationships of this group see Chapman, Bull. Am. Mus. Nat. 

 Hist., iv, 1892, pp. 1-20.)
