HABITAT. North America at large, and south to Brazil and 

 Paraguay; breeding (in suitable localities south to Mazatlan, 

 Mexico. Gray son) northward into the Arctic circle. 



SP. CHAR. "Top of head glossy black, with greenish luster; back and scapu- 

 lars similar, but rather duller, arid sometimes streaked by the appearance of 

 white sides of the feathers the bases of the feathers, however, being plumbe- 

 ous; chin, throat and sides of head chestnut brown, this extending round on 

 the nape as a distinct continuous collar, which is bounded posteriorly by dull 

 grayish; the chestnut darkest on the chin, with a rich purplish tinge. Rump 

 above on sides pale chestnut (sometimes fading into whitish); upper tail coverts 

 grayish brown, edged with paler, lighter than the plain brown of the wings and 

 tail; forehead, for the length of the bill, creamy white, somewhat lunate, or ex- 

 tending, in an acute angle, a little over the eye; a very narrow blackish frontlet; 

 loral region dusky to the bill; a patch of glossy black in the lower part of the 

 breast, and a few black feathers in the extreme chin, the latter sometimes scarcely 

 appreciable; under parts dull white, tinged with reddish gray on the sides and 

 inside of the wings; feathers of crissum brownish gray, edged with whitish, with 

 a tinge of rufous anteriorly (sometimes almost inappreciable). 



"There is no difference between the sexes, but the young bird is very differ-

 by a lusterless dusky brown, the feathers (except on head) being margined with 

 a creamy tint; the neck merely tinged with rufous; the throat has only a dusky 

 suffusion, and the chin is much mixed with white; the frontal patch is obsolete."

These birds, of such wide and extended range, are, during 

 the breeding season, only local in their distribution, forming 

 colonies here and there. They are quite common in the eastern 

 part of the continent, and abundant westward, especially on the 

 plateaus and in mountainous regions. 



In the settled portions they select for their nesting places the 

 vertical banks and overhanging cliffs along the streams, or in 

 the near vicinity of water. Within the settlements they prefer 

 the habitations of man, and build their nests under the project-

 neighbors. Like all the Swallow family, they are birds of the
