NOTES: Other behavior: territory defense? BREEDING STATUS: territorial NOTES ON DATA FORM: Same bird as RRN 90-05-01. After playback of taped saw-whet call this bird would wait a few minutes before responding. This cut has no interruptions (pauses). Tape was started as soon as playback tape was turned off. Owl waits approx 70sec. before initiating return call. Call starts at lower volume and increased speed, slows and increases in volume. ML Notes: The call heard is likely the Advertising call, described in the BNA as a monotonous series of whistled notes on a constant pitch. CZ 08/01/2004. Habitat: Forest, Coniferous Forest, Stream, Riparian, Scrub.
