i S85 .] Henshaw on Birds observed in New Mexico. 3 3 I 



were able to care for themselves, though not yet fully divested of the 

 nestling plumage. Abandoned nests were seen on ledges of rock over- 

 hanging the stream, and one pair had built on a stringer beneath a 

 bridge. 



5. Sialia mexicana. California Bluebird. — A numerous summer 

 resident. Apparently the S. arctica does not breed here. 



6. Myiadestes townsendi. Townsend's Solitaire. — Numerous. 

 Families of young birds in the curious mottled plumage, resembling 

 young Thrushes, were being led through the pines by the old birds during 

 the last half of July. The season of song had entirely passed. 



7. Regulus calendula. Ruby-crowned Kinglet. — Young birds in 

 nestling plumage were taken August 17 to September 11. This was the first 

 intimation received that the species was present. It doubtless nested 

 among the spruces, well up on the ridges. Abundant in fall. 



8. Parus montanus. Mountain Chickadee. — Numerous summer 

 resident; mainly confined to the evergreens. 



9. Parus atricapillus septentrionalis. Long-tailed Chickadee. — Also 

 numerous. Much more frequently seen among deciduous trees than the 

 preceding. Both were conspicuous in fall among the gatherings of small 

 birds. 



10. Sitta carolinensis aculeata. Slender-billed Nuthatch. — Abun- 

 dant summer resident among the pines. 



11. Sitta pygmaea. Pigmy Nuthatch. — Extremely abundant. As 

 soon as the young are out, the different families come together, and birds 

 of various hatchings may be shot from the same flock. I was unaware 

 how much time this species spends on the ground. In a large flock there 

 are always more or less of its members searching on the ground for insects. 



12. Helminthophaga celata. Orange-crowned Warbler. — Fairly 

 numerous in the breeding season, but more so during the fall migration. 

 It seems a little curious that the H. Virginia, which breeds abundantly in 

 middle Colorado, was not detected here at all. It may possibly summer 

 in the foothills, and it doubtless occurs among them in the migrations. 



13. Dendrceca aestiva. Yellow Warbler.— The presence of this 

 species was detected — that was all. Farther down the river it was 

 doubtless more common. 



14. Dendrceca graciae. Grace's Warbler. — This species was one I 

 confidently expected to find as a summer resident. Nevertheless, it was 

 not discovered until after the fall flight had commenced, and the assump- 

 tion is that all the specimens taken, perhaps half a dozen, came from 

 farther north. 



15. Dendrceca auduboni. Audubon's Warbler. — This Warbler 

 breeds abundantly through the pine woods. Young birds were out of 

 the nest July 18, and we saw them gradually assume the fall plumage, as 

 well as the old change to their winter dress. 



16. Dendrceca townsendi. Townsend's Warbler. — This is well 

 known as a Pacific coast species, and one not ascertained to breed any- 

 where in the Rocky Mountain Region. It made its appearance from the
