Dm-ing the migrations, a very generally distributed species, frequenting 



the tops of the smaller trees and low bushes, whence it may often be seen 



darting forth in pursuit of some passing insect. In the breeding season, it 



ascends higher up, and is then found among the shrubbery on the 



open mountain sides. At this season, I have found it as high up as 11,000 



feet. The song is a short simple lay, consisting of a few sweet trills, given 



with considerable spirit, and ending with a rising inflection.
