The most striking feature of the American barn owl is its large, heart-shaped, and white face. It is ringed by darker feathers in stiff, tight rows, known as a facial ruff. This ruff reflects and augments sound similar to a satellite dish, funneling sound waves toward its exceptionally sen...
We consider that the identification of mimicry of predators with Batesian mimicry in the coloration pattern context has caused some unnecessary confusion in that visual mimicry comes about through evolutionary convergence and not learning. None the less, the predictions are that vocal mimics should ...
Unlike songbirds, great horned owls don’t use their call to mate—they use it to notify other owls of their territory. Their call is rather rhythmic; the initial, short “hoo” is followed by a staccato “h’” just before a lower, longer “hoo.” It then finishes off the call with...
If you hear a great horned owl call, that is a great identification aid. Their call is a series of deep hoots, from 3 to 8 notes long, and sounds like - "Whose Awake, Me Too", with the "Me Too" part descending in tone or who-who-ah-whoo, who-ah-whoo. Like a coyote howl, ...
Identification of individual Eastern Screech-Owls Megascops asio via vocalization analysis To more easily and non-invasively monitor urban Eastern Screech-Owl populations, we developed a method of distinguishing individual owls using their calls...

The focus of this study was to determine whether individual vocal identification of Scops Owls was possible and if there was a stability of the hoot-calls over a short time period in the same individuals. Spontaneous vocalizations of 13 owls were recorded in 2004 in Southern Tuscany, Italy. ...
These birds utilize a variety of different vocalizations and sound to communicate. When they want to be heard, they snap their bills, clap their wings, and call out to each other. This is often accompanied by exaggerated body postures such as bowing, bobbing, and dancing, which is most oft...
Oddly, Andrew reports that the sound was coming not from a tree or bush, but from somewhere on the ground. It’s unlikely that Andrew misjudged the origin of the call: he was aiming at it with a parabolic dish, and if the source of the sound hadn’t been close to the focus of the...
I will also review various conflation techniques including what I call theSchulzian transform. These attempt to “stitch together” fragmented classes back into intuitive concepts. I will also review cases where I think materialization of certain classes of shadow are genuinely useful. These include ...
