Next to the Cliff and White-bellied Swallow.s, tliis was tlie most ahiin- 

 dant species of the family. It was found only in the river- valleys, however, 

 or in the lower ravines of the mountains, wdiere, in company with the 15ank 

 Swallow, it excavated the earthy banks or took possession of holes dug l)y 

 the King-fisher {Ccryle alcyon). Its habits in general are quite similar to 

 those of the species with which it so freely associates.

At oidy (ine locality did we meet with this elegant bird, and that was 

 in the Upper Humboldt Valley, where it was common in September in the 

 thickets along the streams flowing from the Clover Mountains. It was 

 found in small companies, feeding on the fruit of a species of thorn-apple, 

 or haw {Cr(tto;(jus rivulurls), which abounded in the thickets.
