Caption

This shows a pair of white-browed sparrow weavers. In these African songbirds, which live in status-dependent groups, it is the dominant males that call the tune -- only they sing a special, complex solo song at dawn. Females and subdominant males, by contrast, perform identical, alternating duets.
