1926] Swarth: Birds and Mammals from the Atlin Region 115 



Ceryle alcyon caurina Grinnell. Western Belted Kingfisher 

 There appeared to be a few pairs of kingfishers nesting in the 

 region about Atlin. The species was far from common but an 

 occasional bird was seen throughout the summer. 



Dryobates villosus leucomelas (Boddaert) 

 Northern Hairy Woodpecker 

 Only three hairy woodpeckers were encountered during the summer, 

 one seen July 6, a male collected on July 7 (no. 44745), and a male 

 collected on August 22 (44746). The two specimens, collected near 

 the town of Atlin, are unquestionably of the subspecies leucomelas, 

 here near the southern limit of that race. In the upper Stikine Valley, 

 150 miles south of Atlin, the subspecies monticola occurs, in fair 

 abundance (Swarth, 1922, p. 217). In the monticola series at hand 

 from that region there are specimens that show intergradation toward 

 leucomelas. 



Dryobates pubescens nelsoni Oberholser. Nelson Downy Woodpecker 



An adult male downy woodpecker (no. 44747), shot near Atlin, 

 June 8, was the only one of the species that was seen. This bird is 

 referable to the subspecies nelsom. It has slightly more black mark- 

 ing on the outer rectrices than is seen in specimens of nelsoni from 

 the Yukon, but in all other respects it appears to be typical of that 

 race. 



Ficojdes americanus fasciatus Baird. Alaska Three-toed Woodpecker 



Unexpectedly rare. The first was seen July 11 ; afterward perhaps 

 five or six, all told, were encountered. One seen at Lake Teslin, 

 September 11. One specimen collected, an adult female, July 11 

 (no. 44748). 



Colaptes auratus borealis Kidgway. Boreal Flicker 

 Present at Carcross when we arrived. May 22, and at Atlin when 

 we reached there a few days later. Breeds in fair abundance through- 

 out the lowlands. A nest hole, partly finished, was found May 31, in 

 a stump in a clearing, one foot from the ground. On June 24 a flicker 

 was seen feeding young in a hole in a dead poplar about three feet
