and in the piny woods of the mountains. At the Old Crater, forty miles 

 south of Zufii, N. Mex., the species was present in large flocks the 2d 

 of November. The surrounding hills arc covered with low scrubby cedars, 

 and upon the berries this and other species largely subsist at this late season. 

 It winters in many of the canons of Southern Utah, where food may be 

 had in plenty, as also in the lower portions of Arizona,

The Audubon's Thrush appears to be a common summer inhabitant of 

 the high Rocky Mountains from Utah to the southward ; its chosen retreats 

 being the deep recesses of the pine woods, but ranging thence upward in 

 the more open groves of aspens to the tops of the highest peaks wherever 

 the limit of trees and shrubbery extends so far. At this season, it appears 

 not to be found lower than 8,000 feet. A temporary camp, near Mount 

 Baldy, in Southern Colorado, was made at this elevation ; and my occasional 

 tramps up the mountain sides in the early morning were often rewarded by 

 choruses, in which these birds were the chief performers, that elsewhere I 

 have never heard equaled. So numerous were they that, after remaining 

 quiet for a few moments, till the alarm caused by the noise of my approach 

 through the tangled masses of uprooted trees had subsided, I have been able 

 to count distinctly eight of these birds. The effect of this burst of melody
