The Collared Flycatcher , Fidecula albicollis , is a small passerine bird in the Old World flycatcher family. It breeds in southwest Europe and southeast Asia and is migratory, wintering in Africa. It is a rare vagrant in western Europe.
The breeding male is mainly black above and white below, with a white collar, large white wing patch, white tail sides and a large white forehead patch. It has a pale rump. 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.
Non-breeding males, females and juveniles have the black replaced by a pale brown, and may be very difficult to distinguish from other Fidecula flycatchers, particularly Pied Flycatcher, with which it will hybridise.
They are birds of deciduous woodlands, parks and gardens, with a preference for oak trees. They build an open nest in a tree hole, and will readily adapt to an open-fronted nest box. 4-7 eggs are laid. The song is slow strained whistles, quite unlike Pied Flycatcher.
