4^ PACIFIC COAST AVIFAUNA. [No. 4 



Petrochelidon lunifrons (Say). Cliff Swallow. 



At various times during the month of April and May I have seen 

 small flocks of Cliff Swallows passing overhead, usually flying at a con- 

 siderable height, but I know of no place in this region where the species 

 breeds. As no specimens were secured it is, of course, possible that P. 

 inelanogastra was also seen, and it may be that all that were observed 

 belonged to that species rather than lunifrons. 



Hirundo erythrogastra Boddaert. Barn Swallow. 



Though the Barn Swallow is an exceedingly common summer resi- 

 dent along the San Pedro River and in the low lands generally in this 

 region, I have seen it along the base of the Huachucas on but very few 

 occasions during the migration. 



Tachycineta thalassina lepida (Mearns). Northern Violet-green Swal- 

 low. 

 A fairly abundant summer resident in the higher parts of the range, 

 breeding from 7500 feet upward, but most numerous along the divide of 

 the mountain. The first arrivals were noted on INIarch 12, 1903, a small 

 flock flying about some live oaks at the mouth of a canyon, but they 

 were not at all abundant until about a month later. Toward the end of 

 July, 1902, after the young were out of the nest, they moved down into 

 the lower parts of the mountains, where young and old were seen to- 

 gether in large flocks ; the young birds being, in many cases, still fed by 

 their parents. 



Ampelis cedrorum (Vieillot). Cedar Waxwing. 



Probably of very irregular occurrence. None were seen either in 

 1896 or 1903, but in the spring of 1902 they were fairly abundant in the 

 lower canyons up to an altitude of 6000 feet. They were seen through- 

 out the month of April, the last obser\^ed being a small flock on May 6th. 



Phainopepla nitens (Swainson). Phainopepla. 



Though this species is an exceedingly abundant summer resident in 

 the lower valleys of this region, it does not, as far as I am aware, breed 

 anywhere in the Huachuca Mountains ; but appears in the spring, during 

 the migration, in limited numbers in the foothills. About the end of 

 July, 1902, a movement began from the lower valleys up into the moun- 

 tains, and during August the Phainopeplas were most numerous through- 

 out the oak region, up to about 5000 feet. At this time they were in 

 loose straggling flocks of from six to a dozen birds, young and old to- 

 gether, and were generally seen sitting in the tree tops and feeding for 

 the most part, as flycatchers. 



Lanius ludovicianus excubitorides (Swainson). White-rumped Shrike. 



A common resident throughout the brush-covered valleys and low- 

 lands generally, breeding occasionally quite up to the base of the moun- 

 tains. I found it most abundant in the Huachucas, though even then 

 OTily in the lowest parts of the foothill region, toward the end of the 

 summer from the last week in July through the month of August ; most 

 of the birds seen being young of the year. The shrikes of this region 

 seem to be rather late in their breeding, compared with the California 

 birds. 



On March 21, 1903, I saw eight or ten birds in one place nei.r the 

 San Pedro River, evidently pairing off ; the males sitting on the tree 

 tops singing, and at frequent inter\'als fighting among themselves or
