115. Genus CHORDEILES Swainson. 
Night-hawk. Bull-bat. Above, mottled with black, brown, gray and 
tawny, the former in excess ; below from the breast transversely barred with 
blackish and white or pale fulvous ; throat with a large white ( ¢@) or tawny 
(@) cross-bar; tail blackish, with distant pale 
marbled cross-bars and a large white spot (wanting 
in the @ ) on one or both webs of nearly all the 
feathers toward the end; quills dusky, unmarked 
except by one large white spot on jive outer 
primaries about midway between their base and 
tip; in the 9 this area restricted or not pure white. 
Length about 9; wing about 8; tail 5. Temperate 
North America, abundant. This species flies abroad 
at all times, though it is perhaps most active 
towards evening and in dull weather; and is gener- 
ally seen in companies, busily foraging for insects 
with rapid, easy and protracted flight; in the 
breeding season it performs curious evolutions, 
falling through the air with a loud booming cry. 
Eggs 2, elliptical, 14 by %, finely variegated. Wits., v, 65, pl. 40; f. 1,2;

~- Var. wenryi is the lighter colored form prevailing in the dryer or unwooded 
portions of western United States; the gray and fulvous in excess of the darker 
hues, the white patches on the wing, tail and throat usually larger. Cass., Ill.

Texas Night-hawk. Similar to the first; smaller; wing 7; tail 4; fine 
gray mottling much predominant above; below rufous prevailing over the 
dark bars ; many broad fulvous bars on the tail, besides the white spots ( 2 ) 
wanting in the 9 ; primaries all sprinkled toward the base with numerous 
fulvous spots; the large white ( g) or tawny (¢) area nearer the tip than 
the bend of the wing, and on only four primaries. Southwestern U. 8S. 
and southward; unquestionably different from the common bird of this 
country, but in adopting the name ¢exensis, I must say that I have not inves-
