Arthur Cleveland Bent, Life histories of North American woodpeckers (1939)
“ Young.—Mrs. Irene G. Wheelock (1904) gives the following interesting account of the young: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. ”
