It is almost certain that the rather peculiar distribu- tion of the various items of food through the season will prove to be more apparent than real in the light of more extensive obser- vations. In the meantime we may safely conclude (1) that the Yellowhead feeds principally upon insects, grain, and weed seed, and does not attack fruit. /.

"When it is considered that the Redwing has been ac- cused of doing immense damage to grain fields, it is evident that the Yellowhead, which has been found to eat nearly three times as much grain as the former, must be capable of much mischief in localities where it becomes ; Data are rather abundant on the occurrence of this species in Wyoming. Cooper reports it from Fort Laramie, 1857; Williston found them abundant at Lake Como; Cones reports.
