Great Grey Owl 1

Great Grey Owl

Scientific name: Strix nebulosa


The Great grey owl’s scientific name, Strix nebulosa, refers to the bird’s screech (strix) and dark, cloudy colouration (nebulosa).

The Great grey owl has incredibly sensitive hearing which enables it to pinpoint the location of a sound. The bird’s hearing is improved by its large facial disk which acts like a satellite dish, funnelling sound to the owl’s ears. Their hearing is so good that they can hear a mouse’s heartbeat under several feet of snow!

This type of owl is crepuscular which means it mostly hunts at dawn and dusk. However, it may hunt in daylight hours or at night-time if food is scarce or if weather conditions are poor.

If breeding is successful, the female will incubate the eggs for 28 days. The male bird will provide food for the female during this time period. Owlets fledge (leave the nest) at around 8 weeks but remain close to the mother for several months before becoming fully independent.
