Nesting Ecology Of The Ferruginous Hawk (Buteo Regalis) In West-Central Utah, John Bradford Weston
Nesting Ecology Of The Ferruginous Hawk (Buteo Regalis) In West-Central Utah, John Bradford Weston
Theses and Dissertations
During the spring seasons of 1967 and 1968 ecological studies were made of nesting Ferruginou.s Hawks (Buteo regalis) in a 325 square mile area in west-central Utah. In the springs of 1967 and 1968 a systematic search was conducted throughout the study area for Ferruginous Hawk nests. When active nests were located they were kept under observation throughout the study. The density of nesting pairs in 1967 and 1968 ranged from 7 to 15.4 square miles per pair. An annual seasonal displacement was exhibited, with Ferruginous Hawks being present in the study area only during the nesting season, which lasted …

Nesting Ecology Of The Great Horned Owl Bubo Virginianus In Central Western Utah, Dwight Glenn Smith
Theses and Dissertations
Information was collected on the nesting ecology of the Great Horned Owl, with particular emphasis placed on aspects of its population and distribution, territoriality and predation. The study was conducted for the two years, 1967 and 1968 in the Thorpe and Topliff hills of central western Utah. Nesting densities on the study area were .36 pairs per square mile in 1967 and .40 pairs per square mile in 1968. Nests averaged one mile apart and were distributed in the periphery of the hills, overlooking the desert valleys. Favorite nest sites were cliff niches, but abandoned quarries and junipers were also …

Niche Differentiating Mechanisms In Two Sympatric Species Of Swallows, David Thomas Moody
Niche Differentiating Mechanisms In Two Sympatric Species Of Swallows, David Thomas Moody
All Master's Theses
The present study considers certain aspects of the ecologies of cliff swallows (Petrochelidon pyrrhonota) and bam swallows (Hirundo rustica) in an area of overlap, where both species are found nesting together and foraging over the same fields. Careful attention was given to foraging flight patterns, foraging elevations, and food consumed by each species in an effort to determine whether or not there is any evidence of competition for food resources. Aggressive interactions between the species were recorded, and the general timing of their nesting cycles was noted.

Papers in Ornithology
Recently, R. I. Smith (1966. Wilson Bull., 78:483-484) questioned, among other things, the occurrence of foraging dives by Pintails (Anas acuta). The authors note observations and published accounts of diving behavior of wild Pintails as well as a number of other surface-feeding species.

Distributional Changes And Interaction Between Prairie Chickens And Sharp-Tailed Grouse In The Midwest, Paul A. Johnsgard, Robert E. Wood
Distributional Changes And Interaction Between Prairie Chickens And Sharp-Tailed Grouse In The Midwest, Paul A. Johnsgard, Robert E. Wood
Papers in Ornithology
The "prairie grouse" of North America present an interesting example of the effects of human activities on breeding distribution patterns of birds, with resulting changes in geographic distribution and spacial isolation. Thus, the Heath Hen (Tympanuchus cupido cupido) was one of the most familiar birds to the early colonists, who relied heavily on it for food. Ultimately, loss of habitat caused the Heath Hen's extinction. When the vast tall-grass prairies west of the Appalachians were settled, Greater Prairie Chickens (T. c. pinnatus) were probably more plentiful, and greatly increased as woods were cleared and grain crops supplemented native grasses. With …
