fornia. This nighthawk had the habit of alighting on the dusty roads, 

 just at dusk, where it sat motionless for a time, though in a few in- 

 stances it was observed to make a series of hopping nights, alighting 

 at short intervals for a moment only. »

Cypseloides niger. Black Swift. 



The black swift was first observed at Owens Lake near Keeler, Calif., 

 where a number were seen flying back and forth over the salt meadows 

 on May 31. On June 2, twenty or more were seen feeding over the 

 same meadow and five specimens were collected. From the condition 

 of the ovaries of the female secured, it was evident that the eggs had 

 been laid. When the flock left the marsh, it rose high in the air and 

 went in the direction of the cliffs in the Inyo Mountains, near Cerro 

 Gordo, where a colony evidently was breeding. Near the upper end of 

 the lake, and about 6 miles north of Keeler, several were seen on June 

 4 and again on June 15. At Lone Pine, five passed over camp early 

 on the morning of June 7, and a number were seen at the mouth of the 

 canon above the town June 12. Dr. Merriam saw a number and secured 

 one at the north end of Owens Lake, June 12, and saw half a dozen at 

 Olancha, at the south end of the lake, June 20. Mr. Stephens saw a 

 dozen or more at the latter place May 23 and secured two June 4. On 

 the former date they were flying high out of range, in company with 

 white-throated swifts and white-bellied swallows. The same observer 

 saw this species at Independence Creek, June 20, and at Bishop Creek, 

 August 6. 



On the South Fork of Kern River three swifts were seen which un- 

 doubtedly belonged to this species, and on several occasions black swifts 

 were seen in Kings Eiver Caiion, August 13-16.
