REPORT UPON ORNITHOLOGICAL SPECIMENS.

1. Turdus pallasii, Cab., var. audubonii, Bd. Audubon's Thrush. 



Abundant, especially in the aspen-groves along the mountain-sides, 

 at an elevation of 10,000 feet, where in early morning I have heard 

 not less than eight males singing in concert. During the breeding- 

 season seldom seen lower than 8,000 feet. A nest found June 7 was 

 built in the cavity of a broken pine-stub about three feet from the 

 ground; was composed almost wholly of strips of bark and coarse 

 grasses covered externally with mosses. It contained a single light- 

 blue egg. 



3. Tnrdus fuscescens Steph. Tawny Thrush. 



This species was found rather numerous along the streams below an 

 elevation of about 8,000 feet. Two nests were found, both built on the 

 ground. One taken June 19 and containing four freshly-laid eggs was 

 curiously enough built in and over the nest of the previous year, the 

 two making a pile some five inches high. Eggs blue, slightly darker 

 than those of the preceding. 



4. Galeoscoptes carolinensis (L.) Catbird. 



In the thickets lining the small streams a few pairs of Catbirds were 

 found. Their nests, built in low bushes and containing freshly-laid 

 eggs, were taken about the middle of June. 



5. Oreoscoptes montanus (Towns.) Sage-Thrasher. 



An occasional pair of these birds were noticed in the sage-brush in 

 the immediate vicinity of Fort Garland, and young just from 'the nest 

 were met with June 20. At the alkali lakes above mentioned a nest 

 was discovered June 22, containing four eggs far advanced in incuba- 

 tion. The nest, a bulky structure of twiggs lined with grass, was 

 placed in a bush some three feet from the ground. Eight or ten inches 

 above the nest was placed a platform of twigs, which, whatever may 

 have been the original intention, certainly served as an admirable 

 screen from the rays of an almost tropic sun. It possibly may have 

 been intended as the site of the nest, and then for some reason have 

 been abandoned for the one beneath.
