Daurian Redstart

The Daurian redstart is a small passerine of temperate Asia, 14–15 cm long and weighing 11–20 g. It is migratory: the nominate form winters in Korea, Japan, south-eastern coastal China and Taiwan, and the subspecies leucopterus in north-eastern India and parts of south-east Asia.

Like all typical redstarts the sexes differ strongly. Breeding males have a grey crown and nape, a black face and chin, a brownish mantle and a large white wing patch, with the chest, lower back and rump orange and the tail black with orange sides. Females are warm brown above and paler below with an orange rump and tail sides and a similar white wing patch. A mated pair of the nominate form has been seen in early May.
