Summary
Species-specific seasonal changes of bird song, that are caused by sex hormones, can be a consequence of distinct gene expression patterns induced in the song control system. In songbirds, different sex hormone activities are based on divergent genomic regulatory mechanisms. However, neuronal wiring of the songbird as well as mammalian brain is modified by sex hormones via to some extent comparable cellular processes.
