Actually, screech-owls do not screech. Some of the vocalizations of the Barn Owl Tyto alba can better be described as a screech (as one of my professors once said, “If you hear a raucous noice in the middle of the night and the hair on the back of your neck stands straight on end, it’s probably a Barn Owl.” In addition, the Barn Owl can rasp, howl, chirp, scream, rattle and make a variety of other noises, most indescribable in print. [Interesting sidenote - the Barn Owl and the similar-sounding named Barred Owl Stryx varia are the only dark-eyed owls in Florida, the rest have yellow eyes.
Returning to the topic at hand (or voice, as the case may be)…
The same inter-species vocalization confusion is likely the
reason the for the name of the Northern Saw-whet Owl Aegolius acadicus, since the call of the Barn Owl is more of a saw-rasp than the call of the Northern Saw-whet Owl is.
The North American screech-owl, unlike the Barn Owl, has a much smaller range of noises. The Eastern Screech-owl Otus asio, or which I am part of the Florida subspecies O.a. floridanus has two distinct calls: a whinny, which is a series of quavering whistles decending in pitch, and a single trill on one pitch - akin to hoo too too too tootootootootootootoo, particularly prevalent in the breeding season (about February to June). The Western Screech-owl Otus kennicotti (similar in appearance to the Eastern Screech-owl) has two calls - a series of quavering whistles accelerating in tempo, and a short trill followed immediately by a longer trill. To the best of my knowledge, no recordings of either species has produced anything akin to a screech.
Now Spider Woman mentioned owl pellets, more aptly termed “castings”, but that’s a whole 'nuther topic.
Hello?
Hello? Anyone there?
Good, everyone’s asleep! My other not-so-secret-in-real-life secret ability works - the ability to bore people with dry factual dissertations.
Now to sneak out of here. I’ve freed myself from the webbings (mostly), but preening’s gonna be hell. This stuff tastes like goo, and my feathers are all stuck. Might be a nice hair gel.
