Glaucidium gromae 1 May 8 SW side of Bass Lake, 3500' alt., Madera Co., Calif. altho I listened for owls last night, I heard none until this morning at sunrise. [scribble] I was scouting the N. facing slope above our camp site about 5:50 AM when I heard a few "hoop" calls from the base of the ridge across the canyon. [scribble] The calls kept on in very indeterminate fashion for some time: - - - - - - -> <- - - - - Then with long pauses before starting in again, as I approached I began whistling & the calls became this regular slow sequence given by this species: -whup- -whup- -whup- -whup- -whup- at about 1½ sec. intervals. As I came up close to where it was calling the sun [scribble] shine on the ground beneath the owl, which was soon found perched about 80 ft. up in yellow pine. As I whistled, the bird flew to another tree some 300 ft. away and perched at similar height. It returned calling when I did & soon came back again. This was repeated 3 or 4 times, always be- tween the same 2 trees, but once it stopped off in the top of a black oak half-way along. Darl Bowers came up from camp & both of us saw the bird fairly well, though not from above. I could see the sharply streaked breast and the yellow eyes clearly, however.
