Evolution Of Communal Roosting: A Social Refuge-Territory Prospecting Hypothesis, James F. Dwyer, James D. Fraser, Joan L. Morrison

Faculty Scholarship

© 2018 The Raptor Research Foundation, Inc. Avian communal roosts provide insight into evolution and serve as focal points for conservation. Nonbreeding Crested Caracaras (Caracara cheriway; hereafter caracaras) use communal roosts, but evolutionary implications have not been explored. Though nonbreeding caracaras are nonmigratory, the scientific literature fails to explain seasonal differences in their movement and survival concurrent with seasonal consistency in their habitat and social ecology. In the Social Refuge-Territory Prospecting hypothesis we propose, socially subordinate nonbreeding caracaras precluded from breeding by habitat limitation use communal roosts as social refuges to avoid aggression from dominant territory holders during nonbreeding seasons, …


Scavenger Interactions In A Human-Influenced Environment: The Foraging Behavior Of The Red-Shouldered Hawk (Buteo Lineatus) At Residential Compost Piles, Eleanor Lucadamo Apr 2012

Scavenger Interactions In A Human-Influenced Environment: The Foraging Behavior Of The Red-Shouldered Hawk (Buteo Lineatus) At Residential Compost Piles, Eleanor Lucadamo

Senior Theses and Projects

Residential composting has increased in popularity in recent years, along with the untested claim that the addition of animal-based kitchen scraps will increase the number of scavenging wildlife visitors. This study represents the first experimental test of that claim. Using three compost piles consisting respectively of no kitchen scraps (CON), a mix of animal and vegetable scraps (MIX), or only vegetable scraps (VEG) that were monitored with heat-in-motion sensitive cameras, we studied the visitation pattern of attracted wildlife. Of the 29 species identified thus far at the compost piles, I chose to focus on the red-shouldered hawk (Buteo lineatus …
