Scops Owls - Ecology and Behaviour

Ecology and Behaviour

Scops owls hunt from perches in semi-open landscapes. They prefer areas which contain old trees with hollows; these are home to their prey which includes insects, reptiles, small mammals such as bats and mice and other small birds. The owls will also eat earthworms, amphibians and aquatic invertebrates. Scops owls have a good sense of hearing which helps them locate their prey in any habitat. They also possess well-developed raptorial claws and a curved bill, both of which are used for tearing their prey into pieces small enough to swallow easily.

Scops owls are primarily solitary birds. Most species lay and incubate their eggs in a cavity nest that was originally made by another animal. During the incubation period, the male will feed the female. These birds are monogamous, with biparental care, and only fledge one young per year. The young of most scops-owls are altricial to semialtricial.

As opposed to screech owls, scops owls have only a single type of call. This consists of a series of whistles or high-pitched hoots, given with a frequency of 4 calls per second or less, or of a single, drawn-out whistle. Calls differ widely between species in type and pitch, and in the field are often the first indication of these birds' presence, as well as the most reliable means to distinguish between species. Some, like the recently-described Serendib Scops Owl (Otus thilohoffmanni), were discovered because their vocalizations were unfamiliar to experts in bird-calls.
