In Yosemite Valley, these woodpeckers were observed during all our visits, winter and summer, in seemingly unvarying though not large numbers. Some days, however, they were very quiet, and might easily be overlooked in one entire morning's census; at other times their nasal chatter sounded almost continually, especially from along the north side of the Valley from the Royal Arches west to below Rocky Point. Often a pair or more made excursions from tree to tree through the cottonwoods around Sentinel Meadow, where they occasionally exhibited the trait of flycatching common to several species of this family. Launching out from a prominent tree top with vigorous wing-beats to waylay a passing insect, they would return in a wide sweep to the starting point. It is not to be inferred from the acorn-storing habit dwelt upon above that insects.
