Abstract/Description

The Northern Spotted Owl, a once thriving species is now a threatened species and on the verge of endangerment. The Barred Owl, a species native to the eastern United States over the past few centuries has expanded its range into that of the Northern Spotted Owl, causing a major threat to the Northern Spotted Owl Populations. This paper is a synthesis of the existing literature of the diets of the Northern Spotted Owl and Barred Owl individually as well as in areas in which they occur sympatrically. With this summary of literature, the reader can gain an understanding of the characteristics and requirements each owl acquires separately and note similarities between the two. Dietary overlap between the two species in areas in which they occur symaptrically can indicate that there exists food competition between the two. Understanding the degree to which the species compete for food can provide scientists with more detail as to how these two species interact and will continue to interact in future years and educate scientists as to which management approaches will be most successful in order to conserve the Northern Spotted Owl populations. Because the Northern Spotted Owl is now a federally listed as a threatened species, it is important to understand the role food competition plays in the recent and rapid decline of Northern Spotted Owls throughout their natural range.
