were feeding their young. [Two specimens, both males, are nearest oliva- 

 ceus, but still not typical of that form. — W. B.] 



Regulus calendula. — Very common during the migrations, arriving 

 March 21 and numerous three days later. They continued in great abun- 

 dance for about a month, when there was a diminution in their numbers. 

 Many pairs breed around the Fort, apparently placing their nests in dense 

 firs. On July 9, at Beaver Meadows, a female was noticed feeding six scarcely 

 fledged young that were sitting close together on a dead twig of a pine 

 tree, in which the nest was probably placed although^ I could not find it. 

 In July and August this species was found in abundance in the mountains 

 north of the valley up to a height of about five thousand feet. Very few 

 of either species were seen in the next five hundred feet, above which only 

 oUvacens occurred. These heights were determined on several mountains 

 by barometric observations, and the distinct range of the two species was 

 very noticeable. 



Myadestes townsendii. — A male taken May 3, and another seen two 

 days later. A few were noticed in July and August in the mountains, 

 where they probably breed. No song was heard. In flight and attitudes 

 this species reminded me much of a Bluebird. 



Turdus ustulatus. — Arrived about May 20, a few nesting near the Fort 

 and in suitable situations in the mountains. Its loud, sweet song was 

 frequently heard about sunrise and sunset, but the birds were shy and 

 difficult to shoot. A nest found June 8, containing four fresh eggs, was in 

 a dense willow thicket, and placed on a horizontal branch about two feet 

 from the ground. 



Turdus aonalaschkae. — A female taken April 29. Not again seen until 

 May II, when after a few days of cold and stormy weather it was found 

 abundantly. They were silent, and rapidly passed on to the north, being 

 seen for about a week only. The basal half of the mandible varies from 

 pale flesh color to a decided yellow, but this is irrespective of sex. [Four 

 spring specimens (one taken April 29, the other three May 11) are well 

 within the maximum limits of size ascribed to aoialaschkcB (their wing 

 measurements are : $ $ , 3.50, 3.55, 3.55; $, 3.23 inches), but their color- 

 ing is very much paler than in any of the California examples before me 

 and, in fact, quite as gray as in average Colorado specimens of atuhiboni.

Merula migratoria propinqua. — Rare during the winter. Arriving 

 March 7, it became common in three or four days. By the first of May 

 many nests contained their full complement of eggs. 



Hesperocichla naevia. — From various sources I learned that this bird 

 Was rarely seen in autumn, but that in March it was generally very abun- 

 dant and tame, coming about the houses in the Fort as plentifully and as 

 fearlessly as the common Robin. I saw none in autumn, and in the spring 

 observed a single specimen only, a female, which I shot April 13, although 

 at both seasons I kept a sharp lookout for the bird. 



Sialia mexicana. — First seen April 4, and three days later was common 

 in small flocks. Breeds about the Fort in greater numbers than does the 

 next species.
