Northern Hawk Owl

Binomial name: Surnia ulula

Category: Typical Owls

Description: Dark brown feathers with cream-colored spots on upper parts; black plumage on the back of the neck.  Underparts and tail feathers are cream with brown bands.  Eyes and beak are yellow.

Size: 14” – 18”, 18” wingspan

Weight: 10.5 oz.

Habitat: Deciduous and coniferous forests near open areas such as clearings, meadows, and swamps

Diet: Rodents (especially voles), hares, weasels, thrushes, grouse, and finches

Nesting: Both parents build a nest, normally in the top of dead conifers or hollow stumps or, more rarely, on cliffsides.  The female lays 3 to 11 eggs and does most of the incubating while the male hunts.  After 25 to 30 days, the chicks will hatch and the female will hunt while the male guards the nest.  After about 3 weeks, the fledglings will begin to leave the nest.

Notes: Northern Hawk Owls are considered a rare bird due to their low population density and remote nesting habitats.  However, if you are lucky enough to find one, they may allow you to approach quite closely.  They are unusually tolerant of humans.  But, if it is breeding season, the males tend to get quite aggressive while defending their young.  Approach with caution.
