Red-naped Sapsucker (Sphyrapicus varius)
June 4, 1937 - Berkeley Camp, Warner Mts., Oregon - This species is abundant in this region, though it may at times show Red-breasted characters in having red in the black upper-breast band. - Workings, in order of their abundance, have been seen on Western Juniper, Aspen, and Fir. The birds, though specially favoring junipers, were not seen in the more extensive juniper groves above 20-mile Creek. The association with Aspen (Populus tremuloides) is of interest as compared to workings of a Red-naped Sapsucker in a small and only group of young poplars on the Berkeley Camps the last winter.
