Hawaiian Owl: This very sacred medium-sized owl is a sub-species of the Short-eared owl. It has light and dark brown mottled upperparts and dark-streaked, pale buff underparts. The head has a large, round, pale-buff facial disk with fine brown tinges, black around the eyes and small ear tufts that look like small ridges along the top of their head. Their eyes are yellow, and the bill is black. Sexes are similar; female is larger.

Breeding and Nesting

Hawaiian Owl: The ground nest is lined with grass and downy feathers and is constructed by the female. It is usually built on a slight ridge with enough vegetation for concealment. Three to eleven white eggs are laid asynchronously, from two to seven days apart, resulting in babies being born at different times. Owlets begin to fly at about 6 weeks of age.

Foraging and Feeding

Hawaiian Owl: Like the eagle and the hawk, these owls are master killers, with ferocious talons and beaks. Their diet includes rodents, rats, mice, insects, small mongoose, and rarely, birds. They forage for prey in open, grassy land, cemeteries, church yards and abandoned ruins. They hunt during the early morning and late afternoon hours.


Hawaiian Owl: Male’s territorial song is a pulsing "voo-hoo-hoo", resembling an old steam engine, given mainly during flight displays; female responds with a barking "kee-ow." When excited near the nest, both sexes squawk, bark, hiss, and squeal.

Similar Species

Short-eared Owl: Long-eared Owl has a smaller "wrist" patch, buff underwings, and a darker belly. Burrowing Owl is much smaller and has a pale bill.
