Lewis’s woodpecker is an expert at catching insects on the wing. When in this act, its perch is some vantage spot, such as the top of a dead tree or a bare limb in the open. Here it sits motionless, except to turn its head from side to side on the lookout for its prey; and when this is seen, the bird glides from its resting place to make a capture. On one occasion for more than an hour, we watched a pair of these woodpeckers seize flying insects, and in that length of time not less than 35 were taken. Through our field glasses we kept a close watch on the birds and soon learned from their actions when an insect was sighted, thus it was easy for us to anticipate its capture, and in not a single instance was a failure made by either of the birds. Once, a light puff of air changed the course of the insect just at the time it was about to be taken, but the woodpecker made a quick turn upward at the same time, dropped its legs straight down, and neatly made the take. When busy catching insects on the wing, this bird leaves its perch by easy wing beats or a long, slow, graceful glide; then, after its prey is caught, rises in its flight and, quickly wheeling, returns to its lookout station. But, as if not content with hunting insects after the manner of a flycatcher, sometimes this bird mingles with the swallows as they hawk over the ground. On one occasion in summer, as we came to a very open pasture, we noticed numbers of barn and cliff swallows in flight over it after insects, and in company with them was a pair of Lewis’s woodpeckers. Back and forth over the meadow flew these dark birds, busy in an attempt to catch flying insects, and their actions as they flew were in marked contrast to those of the graceful swallows. Although we watched the woodpeckers for more than half an hour, throughout that time neither one alighted; and when we left the place both still coursed busily above the field. About one-third of the food of Lewis’s woodpecker consists of acorns. It shares with the California woodpecker the interesting habit of storing acorns, though its method of storing them is quite different, for it seldom, if ever, makes the neat round holes to fit the acorns, so characteristic of the other species; and its stores of acorns are never so extensive, so systematic, or so conspicuous as those of the California woodpecker.
