Flamingos are highly social birds with complex flock dynamics whose welfare in zoological settings depends critically on appropriate group size and appropriate habitat.
Flamingo welfare in zoological settings depends fundamentally on group size - small groups of flamingos cannot exhibit normal social behaviour and show reduced reproductive success and indicators of stress. The highly synchronised social behaviour of flamingos is intrinsically group-dependent; isolated or small-group flamingos are denied a core aspect of their species-typical existence. Dietary provision that maintains appropriate carotenoid levels is both a welfare and health requirement. Zoos that cannot provide large flocks, appropriate shallow water habitats and adequate space for group locomotion cannot meet flamingo welfare needs regardless of other facilities.
