Home: Condition Stimulus Aversion for Fish Crows.

The Fish Crow (Corvus ossifragus) occurs in coastal regions of the Southeast and like most members of the corvid family, both its range and abundance have greatly expanded in the last few decades due to its ability to adapt to urban and suburban environments. While Fish Crows are omnivorous, in some areas they specialize on eggs, particularly those of shorebirds and seabirds. Egg predation by corvids can significantly decrease waterbird productivity. Lethal control has ethical issues and may not be effective if new crows move into the area. During the 2017 season, we explored a relatively new method of non-lethal control that gave a mild electric stimulus to crows taking a decoy egg.
