Orange crest part way back on head with gray behind it. Back was gray-white with black barring. Two of them in the trees around camp. Because of their "cheek" I took them to be Gairdner or Harris at first. Arctic 3-toed Woodpecker -- On way to Patjens Lakes we flushed some from a dense grove. Solid back. They all had the orange patch. Found nest of the Alaska 3-toed Woodpecker in an old snag out on a neck of land at the northeast end of the lake. The entrance was about 10 feet from the ground and faced the east. The young inside chirred all the time and when the snag is rubbed they increased the chirring notes in volume and in speed and pitch. One of the parents brought two loads of food. The other stayed in the next snag and scolded me. (The female). The entrance hole was oval, being 2½" to 2¾" high and 1" to 1¼" wide. The bird always approached from high points, dipped below the entrance level and swooped upward to light a few inches below the hole. Pictures were taken of the nest site, but the parents were too elusive. 9 p.m. Flock of about 25-30 Red Heads came in just at dark, from the north. I was out on a sand bar and they swished directly over my head a few feet.
