The parents are very devoted to their treasures whether they be eggs or infant woodpeckers, and the male rarely fails to stand on guard on a high perch ready to warn and defend should possible danger threaten. The method of feeding is like that of the flickers, by regurgitation for the first two weeks or longer. The adult comes with gular pouch full of food and alights at one side of the nest hole to rest a moment. Though he may have come noiselessly and from the other side of the tree, yet his approach is always heralded by a mowing-machine chorus from the young, plainly heard some yards away. If old enough, the queer-looking little heads are thrust out of the doorway, and the parent, inserting his long bill into the open mouth of a youngling, shakes it vigorously, thereby emptying the food from his throat into that of his offspring. Each in turn is fed in this odd fashion. * * * For a week or two after the young have left the nest, they follow their parents begging for food with ludicrous eagerness; at this time the provender brought them consists of nuts, berries, ants, and the larvae of beetles. These, especially the nuts, are often placed in a crevice of the bark, and the youngster is compelled to pick them out. After a few trials he learns to hammer right merrily and is ready to forage for himself. _Food._--The western pileated woodpecker lives on much the same kind of food as its eastern relative, but naturally on different species of insects and berries. Dr. Harold C. Bryant (1916) examined the stomach of one, taken in Lake County, Calif., on November 5, 1915, and says: “The stomach contained more than fifty carpenter ants (_Camponotus herculaneus_ subsp.) and 131 seeds of poison oak (_Rhus diversiloba_). As the seeds of poison oak are hard and without a noticeable covering of softer material it is difficult to understand what there is about them that is attractive to birds. Certain it is that the seeds are incapable of complete digestion by woodpeckers.” And he adds: “The stomachs of two pileated woodpeckers taken in or near Yosemite National Park * * * were filled with carpenter ants (_Camponotus herculaneus modoc_ Wheeler), many of them winged. Each stomach contained more than a hundred of these ants. In addition one stomach contained a whole fruit of manzanita (_Arctostaphylos nevadensis_ Gray) and the other, four large beetle larvae (_Cerambycidae_), unidentifiable as to genus or species, which had evidently been dug out of some dead tree, as the stomach contained slivers of dead wood.”
