THE WESTERN NIGHTHAWK. “ae 
man from Kansas. He has a perfect right here and he is a very good fellow. 
Oh, to be sure! 
The Pacific Nighthawk differs by scarcely assignable characters from the 
typical form of the eastern United States, but it is separated from it in distri- 
bution by two bleached phases, C. v7. henryi and C. v. sennetti, of the desert 
and plain respectively ; so we feel confident that it represents a resaturation of 
the intermediate stock rather than a division or colony of C. virginianius 
proper. Bird of the plains tho it be, it is pushing its way determinedly on the 
West-side wherever openings offer, and is as likely to occur upon the San 
Juan Islands or in some little clearing of the mountain valleys as upon the 
ampler reaches of the Chehalis prairies. Latterly, also, it has accommodated 
itself to the life of the city, and from the fearless way in which it appears 
over Pacific Avenue in Tacoma, or Second Avenue in Seattle, we judge that it 
must be following the well established eastern custom of laying its eggs on the 
flat roofs of down-town buildings.

THESE Nighthawks are perfectly harmless except to moths, midges, and 
their ilk; and their uplifted wings half careened by the evening breeze furnish
