Nevada in the afternoon. It has never been noted except on the wing, 

 and the flocks have the habit of circling repeatedly over some hill or 

 ridge in quest of insects, at which time they are not easily frightened 

 away by shooting until ready to leave. On one occasion (June g, 

 1913) at Las Vegas eight birds were secured out of one flock under 

 such circumstances. 



191. Streptoprocne zonaris albicincta (Cabanis). 



Hemiprocne zonaris (not Hirundo zonaris Shaw) Bangs, Proc. Biol. Soc. 



Washington, XII, 1898, 158 ("Santa Marta"; crit.). — Allen, Bull. Am. 



Mus. Nat. Hist., XIII, igoo, 137 (Bangs' reference). 

 Streptoprocne sonaris albicincta Ridgway, Bull. U. S. Nat. Mus., No. 50, V, 



191 1, 697 (Sierra Nevada and La Concepcion, in range). 



Additional records: San Lorenzo, 4,500 feet (Univ. Mich. Exp.). 



Three specimens: Pueblo Viejo and San Miguel. 



These specimens agree well in size and color with Costa Rican skins, 

 showing no approach to the characters of 5. sonaris altissima Chap- 

 man. 



This species doubtless ranges over the whole of this region, from 

 sea-level up to the higher altitudes, in its search for food. While 

 blasting out the intake for a flume at Cincinnati on March 19, 1917, a 

 colony of this large swift was discovered nesting in a shallow cavern 

 behind a waterfall. The place was absolutely inaccessible, so that no 

 idea of the number of nests could be had. Only one nest, which hap- 

 pened to be near the top, was secured, together with the occupants, 

 which had been stunned by the blasting, and proved to be an adult fe- 

 male and two recently hatched young. The nest resembled very 

 closely that of the Chimney Swift, being composed of twigs fastened 

 together with saliva. The birds entered and left the cavern by dash- 

 ing through the curtain of water falling over the front of it. The 

 altitude of the site was about 4,300 feet.
