NIGHTHAWK. 



420. Chordeiles virginianus. 10 inches. 



Male with white throat and white band across tail; 

 female with rusty throat and no white on tail. Notice 

 that the Nighthawk has a forked tail and white band 

 across the wings, thus being readily distinguished at a 

 distance from the Whip-poor-will. 



Note. A loud nasal "peent." 



Nest. None, the two mottled gray and white eggs 

 being laid on bare rocks in pastures, on the ground or 

 under brush, or on gravel roofs in cities; size 1.20x.85. 



Range. United States east of the Plains, breeding 

 from Florida to Labrador; winters south of United 

 States. Three sub-species occur: 420a. Western Night- 

 hawk ( henryi ) , west of the Plains ; 420b. Florida Night- 

 hawk (chapmani) ; 420c. Sennett Nighthawk (sennetti), 

 a pale race found on the Plains north to Saskatchewan. 



TEXAN NIGHTHAWK 

 421. Chordeiles acutipennis texensis. 

 This species is found in southern Texas and New 

 Mexico. It differs from the last in having the primaries 

 spotted with rusty, like those of the whip-poor-will
