Mr. Anthony found the Texan nightliawks ' fairly swarming ' at 

 Deming, New Mexico; and in Phoenix and Yuma, Arizona, and in 

 the southwestern parts of Texas, Mr. Bailey found them abundant. 

 They sit in the shade during the day, but at night the air is filled 

 with their 'bubbling cry,' especially about water. At Yuma they 

 would come to the river just after sundown to drink. Hovering 

 close to the water with neck bent down they would take a sip, then 

 fly a little w^ay and repeat it. After drinking they would circle 

 over the water till dark in pursuit of insects. At Owen Lake, Cali- 

 fornia, they were found skimming close to the water in pursuit of a 

 small fly which was swarming on and near the shore. 



Mr. Anthony sa3^s they do not indulge in the aerial evolutions of 

 other nightliawks, but fly low, doing much of their hunting within 

 two feet of the ground, jumping up after passing insects much as 

 the poor-wills do. 



On the wing they are easily told from other nighthawks by their 

 brownness and by the position of the wing bar near the tip of the
