Carriker : List of the Birds of Costa Rica. 705 



mountains. It is most abundant on the high volcanoes, above 7,000 feet. 

 While in that country its habits seem to be very much the same as in 

 Canada, except that it never utters its call, and does not seem to be 

 so shy and difficult to approach as during the breeding season.
