360 Bailey, Birds of the Upper Pecos. ^^ 



parts were olivaceous and the wings were crossed by two yellowish bars. 

 The throat, but not the chest, was streaked, and the belly was whitish, its 

 median line and the under tail coverts being bright yellow. Tanagers 

 were seen on July 19 at 8700 feet and July 25 at 10,200 feet, on the upper 

 edge of the Transition zone. Before this they had been found in the foot- 

 hills between Santa F^ and Glorieta. On August 27 we saw one as low 

 as 6350 feet at the foot of the pine-covered Bernal mesa. 



Progne subis. Purple Martin. — Martins were found near Glorieta 

 July ID. 



Petrochelidon lunifrons. Cliff Swallow. — Seen between Glorieta 

 and Pecos on July 4. 



Hirundo erythrogastra. Barn Swallow. — At 7200 feet Barn Swallows 

 were seen on August 24, and they were common about Mexican adobes at 

 the base of the mountains during the summer. 



Tachycineta thalassina lepida. Northern Violet-green Swallow. — 

 Tachycineta was found from near Glorieta at the base of the mountains 

 up to 11,000 feet, but was most abundant at 8700 feet. Near Glorieta on 

 July 10 we found the Violet-greens nesting in cottonwoods ; at 8700 feet 

 on July 19 they were evidently breeding in crevices in the rocks, flying 

 about the brow of a cliff in great numbers ; and on July 25 we found a 

 large community of them breeding in an aspen grove on the mesa at 

 10,300 feet. A grosvn young was secured in this place on August 14. 

 Mr. Henshaw found the swallows principally in the pine woods. 



Vireo gilvus swainsoni. Western Warbling Vireo. — At Glorieta 

 the Warbling Vireo was singing in the cottonwoods on July 7, and at 

 8000 feet one was singing and carrying food on July 15. Others were 

 found as high as 10,300 feet in the poplars on the mesa. 



Vireo solitarius plumbeus. Plumbeous Vireo. — Mr. Henshaw speaks 

 of ^/«;«/^cK.'; as "rather common in summer," being "almost exclusively 

 restricted to the pines"; but we found it only on the lower edge of the 

 pine belt at the base of the mountains in a cottonwood grove near Glorieta. 



Helminthophila virginiae. Virginia Warbler. — Mr. Henshaw was 

 surprised at the absence of the Virginia Warbler, which "breeds abun- 

 dantly in middle Colorado," and suggested that "it may possibly summer 

 in the foothills." That this is the case we proved by taking a specimen 

 on July 10 near Glorieta on the lower edge of the Transition zone. 



Helminthophila celata. Orange-crowned Warbler. — Taken at about 

 8000 feet on the Pecos July 16. 



Helminthophila celata lutescens. Lutescent Warbler. — Taken at 

 8000 feet on August 19. 



Dendroica auduboni. Audubon Warbler. — These warblers were found 

 from 7000 to 11,600 feet, where, on August 12, they were going about in 

 fall flocks of Juncos, Kinglets, and Warblers. 



Geothlypis tolmiei. Macgillivray Warbler. — Mr. Henshaw, while 

 expecting to find tohniei breeding, saw it only as a migrant late in August^ 

 but we secured a specimen on July 15 on a branch of the Pecos at 8000 

 feet, so it doubtless breeds in the vicinity.
