Flamingos are highly social colonial birds with welfare needs that require specific attention in captive settings.
Flamingo welfare in captivity depends critically on colony size. Wild flamingos exist in enormous social groups, and the behavioral repertoire of flamingos — including synchronized courtship displays, group feeding, and nesting colony behavior — requires large flocks to express properly. Captive flamingo groups of fewer than 15-20 individuals are behaviorally impoverished. Dietary carotenoid supplementation is necessary to maintain the pigmentation that signals health in wild colonies. Their long lifespan creates sustained welfare responsibilities for institutions that acquire them.
