We had always supposed that the rapid series of notes uttered by this species were given only by the adult male and hence constituted a sort of song. But on June 24, 1920, in Yosemite Valley a juvenile male was found, with his head out of a nest hole eight feet above the ground in a dead branch of a live willow, giving every few moments this very series of notes. The large _crown_ patch of red on this bird established its age and sex clearly. There was every indication that the notes were being given as a food call. M. P. Skinner contributes the following note: One seen in Sequoia National Park in August was drilling at the bases of willow shoots near a river. It perched lengthwise of the stems. It managed to keep well hidden, but worked industriously and did not change its position much during the short time that I could see it. Later, I caught a glimpse occasionally of the woodpecker’s red head, although the bird kept hidden most of the time. This reminded me that I had often wondered why red usually marked a woodpecker’s head. Certainly it makes a wonderful recognition mark. In that way it might well be that red on the constantly moving head of the woodpecker would be of value to the race. DRYOBATES BOREALIS (Vieillot) RED-COCKADED WOODPECKER PLATES 9, 10 HABITS CONTRIBUTED BY EUGENE EDMOND MURPHEY Introduced to ornithology by Wilson under the name of _Picus querulus_, the red-cockaded woodpecker is locally common throughout the open pine country of the South Atlantic and Gulf States and extends its range into the pine country of Oklahoma and Missouri. Its preference is very definitely for the open woods, shunning the dense thickets of second-growth pine and the deep recesses of the cypress swamps even when the latter are only a few hundred yards away from its chosen environment. These open pine woods, which abound both in the Austro-Riparian and Carolinian Zones of the South Atlantic and Gulf States, represent not a normal growth of pine forest but an original pine forest modified by the pernicious custom of annually burning the woods under the impression that in that way next year’s pasturage will be improved.
