Iridoprocne bicolor (Vieillot) 



Tree Swallow 



A single example (no. 9183) obtained at Quinn River Cross- 

 ing on May 20. 



Tachycineta thalassina lepida Mearns 

 Northern Violet-green Swallow 



A few of these interesting birds were seen at Quinn River 

 Crossing on May 28. No more were observed until a month 

 later, when four or five individuals were noted flying about the 

 higher parts of the mountains. Observed in Virgin Valley flying 

 about over a pool of water, catching insects. From the observed 

 facts, first, of their remaining all through the summer, and 

 second, of their deportment of themselves in pairs, we were led 

 to believe that they were breeding at the greater altitudes. 



Three specimens were secured (nos. 9179, 9180, 9298), at 

 Quinn River Crossing (4100 feet). Duffer Peak (8500 feet), and 

 Virgin Valley (5000 feet), respectively. 



Stelgidopteryx serripennis (Audubon) 

 Rough-winged Swallow 



Six individuals were seen June 2 at Quinn River Crossing 

 (4100 feet) flying about over the mesa near Wheeler Creek. On 

 July 17 two were observed perching on a bush on Alder Creek, 

 a short distance above the ranch (5000 feet). Two individuals 

 were noted flying about a field at Leonard Creek Ranch (5000 

 feet) on, August 7. 



Two specimens (nos. 9181, 9182) were taken. 



Lanius ludovicianus excubitorides Swainson 



White-rumped Shrike 



Distribution. — Occurred rather commonly on the broad sage- 

 brush flats and to an altitude of 6500 feet in the mountains. 

 A single individual was noted on a sage-covered hillside at 8000 

 feet. Three individuals were observed in the low hills east of
