Bates's paradise flycatcher (Terpsiphone batesi) is a passerine bird belonging to the monarch-flycatcher family, Monarchidae. The sexes are similar in appearance with the upper parts being rufous and the head and underparts being bluish-grey. It is native to central Africa where it is found in the understorey of forests.
Its name commemorates the American ornithologist George Latimer Bates. Bates's paradise flycatcher was formerly considered as a subspecies of the rufous-vented paradise flycatcher but is now recognized as a separate species.[1] An alternate name is the Cameroon rufous-vented paradise-flycatcher.
There are two subspecies recognized:[2]
Bates's paradise flycatcher is usually 18 centimetres long but males in parts of Cameroon and Angola have elongated central tail-feathers making them 23-28 centimetres long. The head and underparts are blue-grey while the upperparts are rufous. The sexes are similar in coloration. The song is a series of ringing "tswee" notes.
The rufous-vented paradise flycatcher is similar in appearance but has a darker head with a crest and males always have elongated central tail-feathers.
It inhabits the understorey of forests. It occurs from Cameroon and the south-western Central African Republic through Equatorial Guinea, Gabon, the Republic of the Congo and much of the Democratic Republic of the Congo south as far as north-west Angola.
