Northern Saw-whet Owl

Eight inches tall with an 18-inch wingspan. It has dark brown plumage, brown and white vertical breast streaks, and no ear-tufts with yellow orange eyes and white “glasses”. Thousands of this seemingly tame, fearless little owl migrate from Canada south through Maine to points south in winter, but some reside in the state throughout the year. Like the screech owl, it nests in tree cavities and will use a nest box. It prefers dense coniferous and broad-leaved forests next to water. It eats small mammals, including shrews and mice, and will also catch small birds and bats. The scientific description of one of the sub-species of this owl is attributed to the Rev. John Henry Keen who was a missionary in Canada in 1896.[2] Adults are 17–22 cm (6.7–8.7…

conserve and recover species listed as threatened and endangered and… In 1990 the Northern Spotted Owl was listed as a threatened under the Endangered Species Act. Since then the rate of loss of habitat has declined. Even so valuable old growth forest is lost to the spotted owls. Previously the decline of the spotted owl population has been attributed to timber harvesting. However, recently the expansion of the Barred owl, an owl of the same genus as the Northern Spotted owl, from east to west…

Spotted Owl The spotted owl lives in western North America and lives in old growth forest. The appearance of the owl is similar to the barred owl but differences include cross shaped marking on the underparts and belly. The owl nests in tree holes, rock crevices or other bird predators nests and can usually be found between 39-179 feet high. The owl usually lays 2-3 eggs but in some occasions can lay four. The owls size as an adult is about 17 inches in height, a wingspan of 45 inches and a…

dilemma on two species of OWLs This Environmental ethical dilemma is on two species of owl – Northern Spotted owl and Barred owl. Northern Spotted owl is a medium-sized dark brown owl sixteen to nineteen inches in length. Most Spotted owls occur on US federal lands (Forest Service, Bureau of Land Management, and National Park Service lands), although significant numbers occur on state lands in all three states, and on private and tribal properties. The northern spotted owl is intolerant of…

Spotted owl populations are rapidly decreasing because of the barred owl invading its land, and scientists are rushing to find a viable solution. The barred owl is encroaching upon the spotted owl’s habitat area, and this is becoming a serious predicament. In states such as California, Oregon, and Washington, spotted owl populations have decreased drastically, and scientists are working rapidly to try to find solutions. These researchers have exhaustively studied the habitat and livelihood of…
