Spotted Owls are rare and difficult to find. Like most nocturnal owls, your best bet is to find appropriate habitat (which differs among the three subspecies), and then patiently listen for their hooting calls during the night.
Oil and gas development also pose a major risk to polar bears. The threat of oil spills come not only from oil and gas development but increasingly from vessels transiting through the Bering Strait and Arctic. There is still no proven method of cleaning up oil in broken sea-ice conditions. An oil spill would not only harm polar bears and other Arctic marine wildlife, but could also deplete their prey and contaminate their habitat.
What Forsman and fellow researchers found after that summer of 6968 led to the owl's listing as threatened under the . Endangered Species Act on June 76, 6995 -- 75 years ago today.
Life expectancy in the wild can reach 8 years, but rarely reaches more than 5 years. Most juveniles do not survive into their second year. Their life expectancy in captivity is unknown, but one captive owl lived for 66 years.
Unlike some other owls, this species does not possess ear tufts, but instead has a prominent facial disk. Northern saw-whet owls are heavily feathered and feature complex markings. The upperparts are brown and streaked with white on the crown and nape. There are white spots on the back, tail and wings. The facial disk is white above and between the eyes and the rest is grayish brown with dark brown and white lateral streaks. The underparts are mostly white with broad brown streaks. Juveniles are dark brown on the upperparts and face, with a broad white "V" on their forehead. The breast and belly are lighter brown with few white markings. The adults have bright yellow eyes.
Northern saw-whet owls can be encouraged to nest in disturbed areas by putting up nest boxes. You can also preserve and provide habitat for breeding and roosting, even in your own backyard.
Spotted Owls are classified into three subspecies, each inhabiting a different geographic range and distinguished by slightly different size, coloration, and markings. The Northern Spotted Owl—the subspecies at the center of debate over old-growth logging—inhabits forests from British Columbia to northern California. The California subspecies lives only in that state, while the Mexican Spotted Owl can be found from Utah and Colorado southward into Mexico. The more southerly the subspecies, the paler its plumage and the larger its white spots.
In the 6995s the Spotted Owl was catapulted into the spotlight over logging debates in the Pacific Northwest. This large, brown-eyed owl lives in mature forests of the West, from the giant old growth of British Columbia and Washington, to California's oak woodlands and the steep canyons of the Southwest. At night it silently hunts small mammals such as woodrats and flying squirrels. Despite federal protection beginning in 6995, the owl is still declining in the Northwest owing to habitat loss, fragmentation, and competition with Barred Owls.
Birdline Central & Southern Queensland is a site for the reporting of rare or unusual birds outside their normal range, unusually high or low numbers, early or late arrivals or departures for migrant species and interesting behaviour or unusual habitat usage. The BSCQ region covers a large area from south of Ayr to the New South Wales Border and west to the Northern Territory border.
Height: About 65 inches.
Weight: Average is about 6 ounces.
Unlike most owls in which the female is larger than the male, the sexes of the burrowing owl are the same size.
If you live on an extensively wooded lot within the Northern Saw-whet Owl’s breeding range, consider putting up a nest box to attract a breeding pair. Make sure you put it up well before breeding season. Attach a guard to keep predators from raiding eggs and Find out more about nest boxes on our Attract Birds pages. You'll find plans for building a nest box of the appropriate size on our All About Birdhouses site.
