The Red-breasted Flycatcher is a small passerine bird. It breeds in eastern Europe and across central Asia and is migratory, wintering in south Asia. It is a regular passage migrant in western Europe.
The breeding male is 12 cm and is mainly brown above and white below, with a grey head and orange throat. The bill is black and has the broad but pointed shape typical of aerial insectivores. As well as taking insects in flight, this species hunts caterpillars amongst the oak foliage, and will take berries. The base of the outertail feather is white and the tail is often flicked upwards as they perch looking out for insect prey which are caught on the wing or sometimes from the ground.
