immediate response to playback of single ksew call

About 10m away in pinyon-juniper forest. Heard calling more distantly and then called in closer with playback.

Toot series, heard a few minutes before dawn, at close range. Next to a lake in a heavily forested area. I was not able to get a visual on the bird.

After attempting to locate the bird in recording XC766381 it didn't move, but started this rather odd alarm call remaining in approximately the same place

Western Screech Owl?

Audio: normalized with 24 bit sample size.

Habitat: mixed aspen-spruce forest in the area of a riparian zone emptying Hospital Lake.

Natural cadence, continued after end of audio but cropped there because of interference from background campground noise.

Series of 4 "wails". remote (unattended) NFC monitoring station on outskirts of small town (Millbrook). NSWO(s) present from late fall through winter.

Remote (unattended) NFC recording station on outskirts of Millbrook, Ontario. 5 "kew" calls followed by song ("tooting"). One (possibly two) NSWO present throughout late fall and winter.

Spontaneous calls heard shortly after another owl species vocalized nearby.

Habitat: north-facing slope with bigcone Douglas-fir, canyon live oak, incense cedar, Coulter pine, white alder, California bay, and montane chaparral.

Equipment: Sony PCM-M10, Sennheiser ME62, and a Telinga 22 inch parabola hand-held. The vocalizations occurred at about 90 degrees relative to where the dish was aimed. Edits: trimmed and normalized to -3 dB, which reduced the volume somewhat.

Recorded in an area with balsam fir, spruce, eastern hemlock, eastern white pine, and various hardwoods. The recording starts with brief burst of "chitters" and then transitions to wails and toots. The first gap, between the chitters and the other sounds, was several tens of seconds (removed due to handling noise and dictation). The second gap occurred when I spliced two files together. Other edits: trimmed and normalized to -3 dB, which amplified the sounds.

Equipment: Sony PCM-M10 and a Sennheiser ME67.
