Stats: Northern Saw Whet Owl

European explorers first discovered this Owl in a North American colony called Acadia (now Nova Scotia). The Latinised word "acadius" refers to this territory. The common name "Saw-whet" comes from these Owls unique calls. The Saw-whet Owl is also called Acadian Owl, blind Owl, Kirkland's Owl, the saw-filer, the sawyer, sparrow Owl, white-fronted Owl, Farmland Owl, Little Nightbird, Queen Charlotte Owl, and even the Whet-saw Owl.

These Owls hunt mainly at dusk and dawn and most often use the "sit and wait" tactic to drop down onto prey on the ground from low hunting perches. They will also range through wooded areas and hunt in heavy shrub cover. When prey is plentiful, a Saw-whet Owl will kill as many as 6 mice in rapid succession, without consuming any of them. The excess food is cached in safe places and, in winter, is thawed out later by "brooding" the frozen carcass. When food is plentiful, it is common for only the head of each prey to be eaten.
Northern Saw-whet Owls feed almost entirely on small mammals, Deer mice being the primary prey, followed by shrews and voles. Other mammals include squirrels, moles, bats, flying squirrels, and house mice. Small birds are sometimes taken and include swallows, sparrows, chickadees, and kinglets. Larger birds such as Northern Cardinal and Rock Dove can be killed by one of these small Owls. Frogs and insects are also part of their diet.

Northern Saw-whet Owls inhabit coniferous and deciduous forests, with thickets of second-growth or shrubs. They occur mainly in forests with deciduous trees, where woodpeckers create cavities for nest sites. Breeding habitat is usually swampy or wet, rather than dry. Riparian habitat is often preferred.

Captive Owls have lived for 8 years, but mortality in the wild is likely relatively high.

Not threatened or endangered. Locally frequent.
