Barn Owls (Tyto Alba) Crossing The Road - Examining The Interplay Among Occupancy, Behavior, Habitat Selection, And Roadway Mortality In Southern Idaho, Tempe Regan
Boise State University Theses and Dissertations
Barn Owls (Tyto alba) are killed by vehicle collisions in greater numbers than any other North American bird of prey. Interstate-84 (I-84) in southern Idaho, USA has among the world’s highest known rates of Barn Owl-vehicle collisions. Little is known about Barn Owl occupancy in this region, so it is unclear if owls are killed in proportion to their abundance, or if they are equally abundant in segments with lower mortality and somehow escape collisions. Furthermore, studies of Barn Owl movements and behavior are limited. I was interested in understanding (1) factors that affect Barn Owl occupancy in …
Behavioral Interactions Of Breeding Bald Eagles (Haliaeetus Luecocephalus) At Lake Cascade, Idaho, Scott Allen Kimball
Behavioral Interactions Of Breeding Bald Eagles (Haliaeetus Luecocephalus) At Lake Cascade, Idaho, Scott Allen Kimball
Boise State University Theses and Dissertations
During the 2000 and 2001 breeding seasons I studied the behavioral inter- and intra-specific interactions of Bald Eagles (Haliaeetus leucocephalus) breeding at Lake Cascade, Idaho. In the first chapter, I describe the relationships between an increase in population density and home range and foraging habitat use by Bald eagles. In the second chapter, I describe the relationship between aggressive interactions and reproductive success, as measured by number of nestlings fledged and nestling weight.
Because home range and foraging habitat use show temporal variability, I compared breeding home ranges and foraging habitat use of Bald Eagles at Lake Cascade, Idaho in …
