Androgen and the elaborate courtship behavior of a tropical lekking bird
In most bird species, male courtship behavior is controlled by testosterone (T) and its metabolites. In species breeding in temperate and arctic regions T circulates at high levels during a relatively short courtship period because high levels of T can be costly in terms of immunocompetence and pare...

In most bird species, male courtship behavior is controlled by testosterone (T) and its metabolites.
