Macaws are long-lived, highly intelligent birds whose welfare in zoos depends critically on pair bonding, cognitive challenge, and opportunities for flight or physical activity.
Macaw welfare in zoo and aviculture settings is substantially determined by the quality of social bonds and cognitive enrichment. Solitary macaws — without a bonded partner — commonly develop feather-destructive behavior, a persistent and difficult-to-resolve welfare problem. Pair-bonded birds show relaxed, engaged behavior and mutual preening that indicates positive welfare states. Cognitive enrichment must be genuinely challenging — macaws quickly solve simple puzzles and require escalating difficulty to maintain engagement. Flight avenues, even within large aviaries, provide physical activity and behavioral expression. The decades-long lifespan of macaws means that welfare commitments must extend across institutional memory — care programs that persist through multiple keeper generations are essential.
