Eurasian eagle-owl in Poland. Most owls are nocturnal or crepuscular birds of prey. Because they hunt at night, they must rely on non-visual senses. Experiments by Roger Payne [1] have shown that owls are sensitive to the sounds made by their prey, not the heat or the smell. In fact, the sound cues are both necessary and sufficient for ...
The eastern screech owl (Megascops asio) or eastern screech-owl, is a small owl that is relatively common in Eastern North America, from Mexico to Canada. [ 1 ] [ 3 ] This species resides in most types of woodland habitats across its range, and is relatively adaptable to urban and developed areas compared to other owls.
Screech owls are typical owls belonging to the genus Megascops with 22 living species.For most of the 20th century, this genus was merged with the Old World scops owls in Otus, but nowadays it is again considered separately based on a range of behavioral, biogeographical, morphological, and DNA sequence data.

The primary call is an accelerating series of short whistles at an increasing tempo or a short then long trill falling slightly at end. Other calls: barking and chuckling, similar to the eastern screech owl. [6] They also make a high pitched screech. The two primary songs for the Western Screech Owl are the bounce and double trill.
Different species of owls produce different sounds; this distribution of calls aids owls in finding mates or announcing their presence to potential competitors, and also aids ornithologists and birders in locating these birds and distinguishing species. As noted above, their facial discs help owls to funnel the sound of prey to their ears.
