It is a Sparrow-sized bird, slightly slimmer and with a long, deeply notched tail, the male has a black head, white collar and a drooping moustache. Females and winter males have a streaked head. Typically found in wet vegetation but has recently spread into farmland and, in winter, into gardens. When singing the male usually perched on top of a bush, or reed.
