Northern Hawk-Owl song and calls

Birdsong and calls are often the easiest way to identify the Northern Hawk-Owl, especially when the bird is hidden in dense foliage. Below is what to listen for.

Song

The male's primary song is a rapid, rolling series of 'hoo-hoo-hoo-hoo' notes, often described as a trill or a rapid hooting, lasting several seconds. It can be heard from a distance.

Calls

Various calls include a sharp 'kew-kew-kew' alarm call, a softer 'whi-whi-whi' contact call, and a 'chittering' sound during courtship or when agitated.

When they vocalize

Most vocal during the breeding season (late winter to early summer), but can be heard year-round, especially during irruptive years.
