Name: Aggressive Bluebirds
Abstract: The researchers tested the aggression of Easter Bluebirds when putting a model of an intruder bird on the bluebirds’ nesting boxes. A model of a House Wren, a known intruder and enemy of the bluebird, was secured to the bluebirds’ nesting box, and the behavior of the bluebird was recorded. The control group had nothing but a white tack on the nesting box. The researchers tested the effects of the treatment, gender of the bird, and stage of the nest on three aggressive behaviors: pecking, hovering, and diving.
