One came flying over with an aspen leaf in its bill and proceeded to shake this leaf about, hammered it on a limb and finally dropped it. All of these birds were molting at this time. Small parties often came down and jabbered at me while I was collecting insects or working over other specimens.

37. Corvus corax sinuatus (Wagler)

American Raven.

Ravens were nesting on the sandstone cliffs below Baigaichi Peak at Red Lake on June 27 and as we were breaking camp in the morning the harsh voiced calls of the young birds were heard plainly. On the summit of the Chusca Mountains Ravens were common. One June 29 several families of young were observed feeding on the ground in broad open mountain meadows. In one opening four of these groups were counted and one on occasion when I came upon several ravens resting near noon in some pines and shot an adult female as she flew out I had 48 Ravens circling above me at one time. The young birds feeding on the ground were deliberate in their actions walking slowly and stopping for considerable intervals to look about. Occasionally one ran or hopped for a few steps after some escaping insect but otherwise they were very quiet. Sticks and cowshipe were turned over with their bills in their search for food. The notes of the young showed some variation from the usual caws and croaks of their parents.

38. [[underlined]] Nucifraga columbiana [[/underlined]] (Wilson)

Clarke's Nutcracker.

This fine bird was fairly common among the Yellow Pines on the summit of the Chusca Mountains but was so shy that it was difficult to find them. They delighted in perching in the tops of tall dead pines
