Daurian Redstart
Phoenicurus auroreus
The Daurian redstart (Phoenicurus auroreus) is a small passerine bird from temperate Asia. In Japan, it is known as jōbitaki (ジョウビタキ). The species was first described by Peter Simon Pallas in 1776.
Its length is 14 to 15 cm and its weight is 11 to 20 g.
Like all typical redstarts, they are strongly sexually dimorphic. Breeding males have a grey crown and nape with lighter forehead and crown-sides, a black face and chin, brownish mantle and wings and a large white wing patch; the chest, lower back and rump are orange, and the tail is black with orange sides. Juvenile males are similarly patterned but much duller and less clearly marked.
Females are warm brown above, paler below, have an orange rump and tail sides, and have a large white wing patch similar to the males. Bill, eye, legs and feet are black in both sexes.
