Abstract
Seasonal changes in circulating steroid hormones, body weights, and social behaviors were measured in a captive flock of Canada geese (Branta canadensis moffitti). The adaptive significance of hormonal fluctuation was interpreted in relation to age of reproductive maturity, social status, timing of nesting events, and reproductive performance.Keywords
