Solo Song Of Tropical Birds Regulated By Testosterone
2012-10-31 15:38:25

Max-Planck-Gesellschaft Experiment in females uncovers male hormonal mechanism In male songbirds of the temperate zone, the concentration of sex hormones is rising in spring, which leads to an increase in song activity during the breeding season. In the tropics, there has been little evidence so far about such a clear relationship between hormonal action and behavior, which is partly due to a lower degree of seasonal changes of the environment. Researchers of the Max Planck Institute...
