Feather destructive behavior (FDB) in parrots and other companion birds is a complex welfare problem linked to stress, boredom, disease, and inadequate environments. It affects a substantial proportion of companion parrots worldwide.
FDB welfare significance extends beyond the behavior itself to what it indicates about underlying states. A bird that plucks its feathers is signaling that its welfare needs are unmet in some dimension - physiological, social, or environmental. The challenge is that FDB has multiple causes requiring differentiated responses, and behavioral causes require behavioral solutions while medical causes require medical treatment. Many companion bird owners lack access to avian veterinarians or behavioral expertise. The welfare system for companion birds is less developed than for dogs and cats, with fewer trained professionals and less research into effective interventions.
