Remsen, J.V. 1974 Spotted Owl Strix occidentalis May 3 (cont) not seem bothered by the flashlights. I have heard others say that this species is not alarmed by shining flashlights on it. The male hooting is of three types (1) a single barking hoot which seems to be the first call given in response to an imitation (2) a four hoot call hooo pitch hoo-hoo 1 1/2 - 2 seconds (3) a series of hoots (5-15) given in rapid succession, which usually increase in intensity as well as interval between hoots toward the end of a series. This seems to be the call given when most aroused or "angered". Whether these three calls apply only to Muir Woods Spotted Owls is not known since it is only there that I have had "extensive" experience with the vocalization, (twice). This bird has eluded me so many times that it was one of the biggest thrills I've ever had in birding to finally see them so well - I figured that I had made attempts to see this species on 20 previous occasions. May 11 Oak Creek Canyon, Coconino Co., Ariz: I h.o.- hooted once - series of four hoots as described above May 22 Alice Eastwood Camp: an exact replica of the May 3 trip was done but no owls were seen or even heard. June 15 James San Jacinto Mtn. Reserve, Riverside Co., Calif: I seen (silhouette) and heard. Also calls which may have been juvs. of this species were heard - nearly identical to recording of juv. Spotted Owl on Peterson record.
