Marshall (1942) Myadestes obscurus V de Santa Ana noted in abundance together on Cerro del Aguila where underbrush cut and all along the road. I nest found in road bank near saddle. Birds very tame, easy to approach and in open woods where easy to see. Sing from middle freights of large trees which means the lowest branches 60 or more ft up. Sit on little peripheral twigs very motionless. Sing just about all day. Behavior much different from Los Eses miles where only in densest low trees.
