Functional analysis and treatment of self-injurious feather plucking in a black vulture (Coragyps atratus).

The etiology and maintenance of self-injurious feather plucking (FP) have been attributed to biological and environmental processes, yet a definitive solution has not been found. The current study investigated the application of a functional analysis and function-based treatment to reduce the FP of a black vulture (Coragyps atratus). FP was found to be maintained by positive reinforcement in the form of contingent attention. A treatment consisting of noncontingent reinforcement decreased FP, and levels of FP remained low during schedule thinning. The current study further demonstrates the validity of function-based assessment and treatment with captive animals.
