Flamingos are highly social colonial birds whose welfare depends on large group sizes and appropriate environmental conditions.
Flamingo welfare in zoos is fundamentally a question of scale — these highly colonial birds evolved behavioral and reproductive systems requiring large aggregations that few zoos can provide. Small flamingo groups show social instability and poor breeding success reflecting the mismatch between natural social needs and captive group sizes. Institutions with large flamingo flocks and appropriate water and feeding conditions achieve substantially better welfare outcomes.
