Marshall, 1938 5. Otus flammeolus Whitakers - contin. at downward slant as of heading for gnd. Typical screech owl form: long, broad wings, large head in front, short tail behind; swift, direct flight. Commenced to hoot 25 yd. up hill. I followed past stump with hole (NO NEST) to open group sm. cedars with few and open branches & bare humus beneath. Owl calling softly from within these. Seen on small limb 3 ft. above gnd.-Forages at gnd. like Screech Owl? Not arboreal feeder. Ovidus-ly foraging since not calling much. Calls after feeding. Form & eyeshine similar to asio. Even light grey color in flash light. Tapers from a head, almost to point, where wings end behind tail. No ear tufts visible. Seen at 15 ft., changed to .410 aux in open choke. Owl leaned-to-side turned to side and leaned forward as screech owls do preparatory to flying. Paused then took off lig lightly & swiftly. Continued to call in neigh-boring cedar. I got directly in front of it as it sat on long branch of low cedar & 4 ft. off gnd. Eye-shine visible, turned head from side to side. Collected- #377 male, body & full stomach in formalin. 1/2 h. after dark (about 8:PM) May 22 Returned in evening to call, hoping to hear mate or find nest. None found. Solitary due to rareness. Asio always in pairs even after breeding. Proximity to Otus asio in Public campgnd. in summer 1928 1935. Definite transition zone, (shot in cedar). Continuity of hooting - slave to glands? Why hooting in 1st place? Territory or attraction to female ? Tried giving hypothet-ical female call, higher; no effect. Very tame, flushed only when I climbed oak & at shot & tapping trunk. (Therefore climbing mammals a possible enemy.) Definite restricted territory & love of cover & success in keeping out of si sight. Calling prolonged & often started by my hoots. Curiosity or territoriality . Imitated hoots very accurate, probably second.
