Northern Grey Owl Strix nebulosa

The harvesting of timber in the pacific northwest has lead to great habitat lost for the owls. With out large areas of forests the Owls cannot hunt very as well as they would like. Lose of nature habitat, while well documented in the US and Canada, is more extreme in Europe. Juvenal owls require fallen trees to nest in and adults require branches to perch after, or while hunting. Clear cutting forests removed any chance of this, and eventually lowered the population size to endangered.

Northern US, Canada, Russia, Estonia, and Finland. The Owls mostly live in coniferous forests of the taiga. While the owls do not migrate, they are slightly nomadic depending on amounts of food in the area.

The Owls are one of the top predators of their area, and being the only non-migrating major predator play an important role during the winter months.

Northern Grey Owls have extraordinary hearing and eyesight, needed for dusk and night hunting. The Owls can identify prey, which in some cases can be two feet under the snow, and easily retrieve it. The Owls cannot create their own burrow, but instead have to resort to stealing other bird’s nests. The owls range from 24-33 inches and have wingspans ranging from 60-50 inches. Adults create low and rhythmic whoos, while juveniles may shrike or hiss. The Owls can also live up to 40 years

Slowing, or in some cases completely stopping logging has helped rejuvenate the owls population, but is sadly not fast enough. In the Pacific North West drastic measures have been taken in order to save the Owls. Some hot spots have been completely closed to loggers. This has had a profound affect on the Owl populations, and looks as if it will help their recovery.
