Reproductive Failure And The Stress Response In American Kestrels Nesting Along A Human Disturbance Gradient, Erin Hennegan Strasser
Reproductive Failure And The Stress Response In American Kestrels Nesting Along A Human Disturbance Gradient, Erin Hennegan Strasser
Boise State University Theses and Dissertations
Human disturbance may be an influential environmental stressor that affects birds across life stages. I examined whether external and endogenous factors including habitat type, habitat quality and individual quality (hereafter quality), or human disturbance affect American Kestrel reproductive success in southwestern Idaho. Specifically, I was interested in how these factors lead to nest failure or abandonment. I also investigated whether elevated corticosterone (CORT) concentrations mediate the relationships among explanatory variables and nest failure. As nestling kestrels may respond to stressors differently from adults, I examined whether conditions experienced during the nestling stage affected nestling American Kestrel (Falco sparverius) hypothalamic pituitary …
