HOYT HORNED LARK. 



A. O. U. No. 474k. Otocoris alpestris hoyti Bishop. 



Description. Similar to O. alpestris, but the yellow of throat paler or re- 

 stricted to central stripe ; the eyebrow white or, rarely, slightly yellowish. Seasonal 

 and sexual changes like preceding. 



This seems to be a well marked subspecies. I have examined specimens from 

 Columbus, Wauseon, Oberlin, etc., all clearly referable to this type. 



This is the bird of the northern interior of British America. Its winter range 

 overlaps that of O. alpestris, tho lying mostly to the westward. Large winter 

 flocks often contain both forms in about equal proportions. 



Average measurements of 15 males: wing 4.37 (ni.i); tail 2.77 (70.5); 

 exposed culmen .45 (11.4) ; tarsus .88 (22.3) ; middle toe .49 (12.5) (Oberholser). 



Taken in Colorado.
