Book excerpt: As part of Kids' Planet, Defenders of Wildlife presents a fact sheet on the northern spotted owl (Strix occidentalis caurina), which is a threatened species. Northern spotted owls are territorial and do not adapt well to habitat disturbances. The fact sheet provides a description of the owl and highlights information on such topics as the lifespan, size, habitat, diet, behavior, and offspring of the owl.

Available in PDF, EPUB and Kindle. Book excerpt: The Northern Spotted Owl, a threatened species that occurs in coniferous forests in the western United States, has become a well-known environmental symbol. But how is the owl actually faring? This book contains the results of a long-term effort by a large group of leading researchers to document population trends of the Northern Spotted Owl. The study was conducted on 11 areas in the Pacific Northwest from 1985 to 2008, and its objectives were both to evaluate population trends and to assess relationships between reproductive rates and recruitment of owls and covariates such as weather, habitat, and the invasion of a closely related species, the Barred Owl. Among other findings, the study shows that fecundity was declining in five populations, stable in three, and increasing in three areas. Annual apparent survival rates of adults were declining in 10 out of 11 areas. This broad, synthetic work provides the most complete and up-to-date picture of the population status of this inconspicuous forest owl, which is at the center of the complex and often volatile debate regarding the management of forest lands in the western United States.

Available in PDF, EPUB and Kindle. Book excerpt: In the ancient forests of North America lives a nocturnal hunterthe spotted owl. With its keen eyesight and hearing, it listens and watches for prey. From western Canada to Mexico, and in the states between these two countries, wildlife biologists are observing and counting spotted owls. Once abundant in number, this flying predators days on earth may be limited if changes arent made. In this book, read about out how this owl lives, what threats it faces, and what scientists and activists are doing to help it. Then find out what you can do to help save this threatened bird.

This book was released on 2012 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fourteen nest sites of the endangered Northern Spotted Owl (Strix occidentalis caurina) in British Columbia were sampled in 2003 and 2004. Nests were located in three broad ecosystem types: the maritime (n = 1), submaritime (n = 6), and continental (n = 7) ecological subregions. Spotted Owls exhibited flexibility in their use of different types of nest structures across their broad ecological distribution. The objectives of the analyses are (1) to describe 14 of the 16 known nest structures, nest patches, and nest stands relative to the ecological subregions in which they occur; (2) to test for habitat selection within the nest stand (patch-level) and within the local landscape that the authors defined as the area containing the forest nest stand and forest stands greater than 140 years old adjacent to it (stand-level) relative to the ecological subregions; and (3) to evaluate how local British Columbia nesting habitat information was incorporated into interpreting "Superior" owl habitat for a revised spotted owl management plan.--Document.
