June 7
Walked N. on the highway from camp (at the bench mark at the bend of the river) to the 1st road cut. Just past this cut a little draw leads up to the east-heavily wooded & a ridge on its north border is more open. Went in here & called for O.flam., Cryptogamus, & just as I left, gave 2 spotted owl hoots & a couple of horned " " . I reached the road in about 1/2 min. & just then a ♂ spotted owl gave a burst from a tall dead tree on the ridge.
In a few more minutes he was down in the dense timber of the draw answering my calls, showing a good pink eyeskin, & perching on little stumps on the clean trunks. Collected it, at 1458 stomach contained 4 whole orthopterans which I saved.
Gave the typical calls but very loudly- Also the ascending series of hoots leading to regular call. Often the last hoot had a yodel in it.
