Owl Calls

Territorial calls in the Little Owl

Territorial calls in the Little Owl ( Athene noctua )

Alarm calls modulate the spatial structure of a breeding owl community.

Animals should continuously assess the threat of predation. Alarm calls inform on predation risk and are often used as cues to shape behavioural responses in birds and mammals. Hitherto, however, the ecological consequences of alarm calls in terms of organization of animal communities have been neglected. Here, we show experimentally that calls of a resident nocturnal raptor, the little owl Ath...

Differential behavioural and hormonal responses of voles and spiny mice to owl calls.

Rodents usually respond to the presence of owls by reducing overall activity, in particular foraging. In this study, a playback of recorded tawny owl, Strix aluco, calls was sufficient to induce a marked effect in the social (Gunther's) vole, Microtus socialis. Some of the voles exposed to owl calls reduced their activity ('freeze' pattern) unlike control voles exposed to a human voice. Other v...

Humane OWL: RDF and OWL for Humans

Humane OWL (HOWL) is a syntax for RDF and OWL designed for manual editing. By allowing human-readable labels to be used in place of IRIs, and providing convenient syntax for OWL annotations and expressions, HOWL files can be used like source code with tools such as GitHub, then translated into any other RDF or OWL format for use with other tools.
