Main Characteristics


Barred Owls are large owls that are between 43 and 50 cms (17 - 20 inches) in length, they have a wingspan between 99 and 110 cms (39 - 43 inches) and they weigh between 470 and 1,050 g (16.6 - 37 oz).

Their upperside is mottled grey in colour and their underside is pale grey. They have dark coloured markings in the form of bars that run horizontally across their chest and vertically down their front.

Their head is rounded in shape and they lack any ear tufts. Their beak is yellow and they have brown coloured eyes. Their legs and feet are covered with feathers up to their talons.

Barred Owls are highly vocal and their usual call consists of a series of eight hoots. When they are agitated they will make a rasping hiss and other calls include a short barking sound.

Habitat

Barred Owls are found in the dense forests, wooded swamps, and woodlands of North America. At night they hunt in their territory which is between 85 and 365 hectares (213 - 903 acres). During the day they spend their time hiding among the dense foliage high up in a tree.

Diet

Barred Owls feed upon a variety of prey including mice, voles, shrews, moles, rats, squirrels, opossums, mink, weasels, birds, bats, young rabbits, snakes, lizards, frogs, fish and insects.

They are opportunistic hunters and they wait high up on a perch then swoop down on their prey. They usually eat their catch straight away, but bigger catches are taken to a perch before they are consumed.

Breeding

Barred Owls begin courting in February and they breed between March and August. They nest in tree cavities and will often reuse an old nesting site of a crow, squirrel or hawk. They pair up for life and they will often return to a particular nesting site for several years.

2 - 4 round, white eggs are laid and after an incubation period of 28 - 33 days the chicks hatch. The young owls leave the nest when they are around 4 weeks old, but they are not able to fly at this stage and they perch on branches near their nest.

The chicks fledge when they reach 35 - 40 days old but their parents care for them for at least 4 months.

Predators

The only natural predators of Barred Owls are great horned owls.
