Pisobia minutilla (Vieillot). Least Sandpiper 



Seen at Carcross May 22. At Atlin the first south-bound migrants 

 appeared June 29, when two single adults were seen at different points. 

 One of the birds was performing the usual mating flight. A few days 

 later small flocks began to drop in at intervals, continuing until 

 August 27, when the last was seen. 



Ereunetes pusillus (Linnaeus). Semipalmated Sandpiper 



A single bird, a south-bound migrant, was collected at Atlin, 

 July 17. This specimen (no. 44649) is an adult female, in which the 

 annual molt has just begun. Two were seen at close range on the shore 

 of Morley Bay, Lake Teslin, September 12. 



Totanus flavipes (Gmelin). Yellow-legs 



Present in some numbers at Carcross, May 22, and evidently then 

 preparing to nest. The birds were in pairs and noisy and solicitous at 

 any invasion of their territory. Some were going through the nuptial 

 flight and "song," some perched on tree-tops scolded the intruder. 

 About Atlin there were yellow-legs in nearly every lowland swamp. 

 While the breeding birds were thus distributed in pairs over the 

 country, there were also wandering flocks that appeared at intervals 

 during June and July. These were evidently composed of non-breeding 

 individuals. 



We found no nest, but Brooks collected a newly hatched chick on 

 June 17. The downy young Jjad the faculty of remaining invisible, 

 or nearly so, but when almost full grown they became conspicuous 

 about the edges of the ponds, and were then indifferent to approach. 

 By July 20 the yellow -legs had nearly all left for the south ; the last 

 birds were seen August 13 and 14. 



Three specimens were collected by me, young nearly or quite full 

 grown (nos. 44650-44652). 



Tringa solitaria Wilson. Solitary Sandpiper 



First seen at Carcross, May 25. Early in June the species was 

 encountered not uncommonly about Atlin, and the birds seen had all 

 the appearance of being upon their nesting grounds. Individuals were 

 going through their courting flight and song overhead, and some were
