Food-niche Relationships Between Great Horned Owls and Common Barn-Owls in Eastern Washington
organs. There are only two serious limitations to using feather pulp for electrophoretic analysis. First, the birds must either be molting when sampled or be subjected to plucking to stimulate feather regrowth and then recaptured at a later date. Second, in small birds such as Bobolinks, warblers (Parulidae), or chickadees (Parus spp.), only tiny amounts of tissue can be obtained from the fligh...
متن کاملGreat Gray Owls (Strix nebulosa) in Yosemite National Park: on the Importance of Food, Forest Structure, and Human Disturbance
4 Corresponding author: charles_van_riper@ usgs.gov; 520-491-0721 ABSTRACT: We studied great gray owls (Strix nebulosa Forster) in Yosemite National Park, California, measuring variables that could potentially influence patterns of occurrence and conservation of this stateendangered species. We found that owl presence was closely tied to habitat (red fir (Abies magnifica A. Murray) and the abun...

(Speotyto cuniculuria) to a moving object when the object did and did not cast a conspicuous shadow. We used a single Burrowing Owl for all tests. It was trapped about 5 km north of Davis, Yolo County, California. We chose this species because it is easily trapped and because it often feeds nocturnally upon terrestrial prey, including rodents, and therefore may exploit shadow cues (Thomsen, Con...
متن کاملNon-territorial Floaters in Great Horned Owls (Bubo virginianus)
—The ecology and behavior of non-territorial owls are basically unknown. I studied the integration of young Great Horned Owls (Bubo virginianus) into the territorial breeding population from 19881993 in the southwestern Yukon, Canada, during a peak and decline of the population cycle of snowshoe hares (Lepus americanus). Fiftyfive fledglings were equipped with radio-transmitters that allowed we...
متن کاملRange-wide genetic differentiation among North American great gray owls (Strix nebulosa) reveals a distinct lineage restricted to the Sierra Nevada, California.
Investigations of regional genetic differentiation are essential for describing phylogeographic patterns and informing management efforts for species of conservation concern. In this context, we investigated genetic diversity and evolutionary relationships among great gray owl (Strix nebulosa) populations in western North America, which includes an allopatric range in the southern Sierra Nevada...
