yale-a-min and McDonald Lakes. It did not appear 

 to be nesting as commonly elsewhere as at Flat- 

 head Lake, as no nests of the season were found. 

 However, a nest was found along the trail beside Sin-yale-a-min 

 Falls, on a horizontal branch directly above the head within 

 reach of the hand, containing two eggs, July 11. The notes 

 of the olive-backed thrush were regular features of the woods 

 during our stay at Sin-yale-a-min. 



Abundant in all localities near the Station, and breeding in 

 numbers in June. Probably disappears from the neighborhood 

 about the middle of August, as our last notes regarding its 

 presence were made on August 9. 



761 a. WESTERN ROBUST, Merula migratoria propinqua 



Ridgw. 



We did not find the robin as common near Sin-yale-a-min 

 Lake as might be fancied. With the exception of one family on 

 the northern shore of the lake, we did not note the occurrence 

 of this species. In this instance, the parents were feeding- 

 young still in the nest. 



A nest was found on the cliff-side east of McDonald Lake in 

 a clump of maple, with three eggs. The robin was observed 

 visiting the water falls in the face of the cliff, to bathe and 

 drink. 



Abundant in the vicinity of the Station as a summer resident. 

 In the second week of August, the robin was observed in small 

 flocks of ten to twelve. During the last week of August, the 

 robin was feeding greedily on the black haws, associating with 

 the cedar waxwing at the plenteous banquet. 



768. MOUNTAIN BLUEBIRD, Sialia arctica Swains. 



Not common, but occasionally observed and noted in our lists. 

 A specimen was taken on Mt. McDonald at an elevation of 

 7,500 feet.
