 Jan., 1914 NOTES ON NESTING OF THE SHARP-SHINNED HAWK 23 young bird in a nearby tree. After I had climbed three trees it finally escaped in a dense thicket and I gave up the chase. The mother bird would alight quite near while I was climbing for the young, and utter a plaintive "cheap, cheap". I carried the two young hawks to the edge of the thicket and perching them on a dead limb made several negatives of them.

Late in the afternoon I heard one of the old birds call and had just caught a glimpse of its wings when all the young uttered a faiut "cheep, cheep", and flew to a tree some distance off. After a short time tvo of the young returned to the dead tree: one remained avay some time, finally returning to the other tvo. I remained quite late but observed no further evidences of feeding, so returned home. On the st of August the last down had disappeared from the captive birds, that being on top of the head. They seemed to stand captivity very well but re- mained extremely wild. I kept their cage hung well up in a tree, and fed them exclusively on raw beef, three ounces for both birds at a meal, morning and eve-
