Abstract
To elucidate the possible utilization of gonadal sex hormones by the nuptial plumage producing skin, histochemical localization of 3β-, 3α- and 17βhydroxysteroid dehydrogenases was carried out in the skin from crown region (characterized by bright yellow plumage) and ventrum, and testes of the Baya weaver birdPloceus philippinus (L) during the breeding phase. Results indicate higher activity of 17β-hydroxysteroid dehydrogenase in the crown skin, when testosterone was used as substrate. Possibly, skin from the crown region actively metabolizes androgens and this in turn is correlated to the production of nuptial plumage.
