Howell, T.R. 1948 Sphyrapicus varius daggetti 8 mi. N. and 13 mi. W. of Canby, 4700 ft., Modoc Co., Calif. May 22 (cont.) its head and body up and down and raising its crown feathers slightly. The other two approached this one (or each other) from either end and then all three flew off again. All the rest of the morning I heard screaming and drumming. I watched one bird pursue another around through the trees seemingly with mating rather than mayhem on its mind, since they flew about in the same area without any apparent attempt on the part of the pursuer to drive the other away from the region. The small tree in which I collected the first sapsucker seems to be a favored one for feeding; it is a pine about 10 inches in diameter near the base and about 20 ft high. There was a series of fresh workings on the trunk about 10 ft. up, and I came up close (30ft.) and watched. A moment later a sap- sucker alighted in this spot and began picking at the freshly opened holes in the bark. This bird was not typical daggetti as it had a dark auricular patch showing through the red and a definite white superciliary for post-ocular stripe. Then it began pecking another hole just above the top one in a series.
