Yukon." They are common in the Mackenzie Delta (Porsild, 1943) 

 and through Alaska. The plentiful nesting population on the Porcu- 

 pine, apparently a main connection between abundant Mackenzie 

 and Alaskan nesting populations, implies that the migration to the 

 Porcupine is either from the west or from the east since central and 

 southern Yukon seem to be but little visited by snipe.

A whimbrel was heard on May 24 on the sedgy saddle extending 

 for about a mile between the southern and next northern of the Old 

 Crow Mountains. Hummocks of sedge interspersed with lichen cover 

 extended over this gently sloping saddle at elevations from about 

 1,600 to 2,000 feet. On May 25 two pairs were watched and four 

 other whimbrels were flying about calling the trill which resembles 

 the loud call of a tree frog. These birds often landed and all appeared 

 to be attached to the locality. 



Two whimbrels were seen at the same place on May 27 and Father 

 Mouchet saw several on May 29. On June 4 Sidney Peyton collected 

 a male bird and two sets of four slightly incubated eggs which must 

 have been first laid about May 27. On June 9 three pairs were again 

 seen on the same saddle. The larger appearing bird of one pair was 

 collected and turned out to be a male with a brood patch. Both of 

 these birds were observed calling, were unwilling to leave the vicinity 

 in spite of an hour of pursuit and several shots fired at long range. 



Whimbrels, which the Indians call Tetnjyo, nest on tundra loca- 

 tions in arctic Mackenzie, Yukon, and Alaska. They are rare in the 

 remainder of Yukon (Eand, 1946), and are common migrants only 

 along the coast of British Columbia (Munro and Cowan, 1947) . It is 

 indicated that the arctic nesting population comes from the migra- 

 tion along the Pacific coast, and presumably reaches arctic Yukon and 

 Mackenzie from the Yukon Valley after crossing the mountains from 

 the Gulf of Alaska.
