Finsch's Flycatcher-thrush, [Also Finsch's Rusty Flycatcher, Finsch's Ant Thrush, Finsch's Rufous Ant Thrush, Finsch's Rufous Thrush] "Neocossyphus" (or "Stizorhina") "finschi", is a little-known flycatcher-like thrush of West African forests. It is often considered a subspecies of the Rufous Flycatcher-thrush.

Range and habitat

This species lives at low levels in the thickest parts of forests, often near stream or damp areas or in wooded swamps, from sea level to 1500 meters (about 5,000 ft), in the southern parts of Sierra Leone, Liberia, Ghana, Benin, and Nigeria. (A record from southern Togo may represent a small population there.) It is sedentary.citation | last = Clement | first = Peter | year = 2000 | title = Thrushes | publisher = Princeton University Press | pages = 180–181, Plate 1 | isbn = 978-0-691-08852-5]

It is rare in many areas, but locally common.

Description

Finsch's Flycatcher-thrushes are 18 to 20 cm (7¼ to 8 inches) long. Adults are brown above and orangish below, more gray or olive on the nape and breast and more rufous at the rear of the body. The tail is dark brown with white corners. The cheeks and throat are pale with gray and orange tints.citation | last = Demey | first = Ron | year = 2002 | title = A Guide to the Birds of Western Africa | pages = 605, Plate 92 | publisher = Princeton University Press | isbn = 0-691-09520-5] Immatures are undescribed.

The voice is similar to that of the Rufous Flycatcher-thrush. In Liberia it sings from May to October. The song is four melodious whistles, "hooee, hooee hooee-huEE", slower and lower-pitched than song of Rufous Flycatcher Thrush". One call is four rapidly repeated notes, "tswe-tswe-tswe-tswe" with the variant "tsw-tsee… tsweeeee"; another is "a long, plaintive whistle "wee… weeeee-eee"." In alarm caused by predators it gives a "buzzing "word-word-word"." Unlike the Rufous Flycatcher-thrush, this species responds to recordings of its call.

Behavior

Finsch's Flycatcher-thrush usually occurs alone or in pairs. During the breeding season it is highly territorial, but at other times it may join mixed-species flocks at ant swarms. However, it relies much less on ant swarms than two of its fellow members of the genus "Neocossyphus", the White-tailed and Red-tailed Ant-thrushes. Instead it catches insects in its beak like a flycatcher, hawking from perches or taking them from under leaves while it hovers. Favored insects include termites, grasshoppers, ants, beetles, flies, and various small species. It may sit for a long time without moving on a horizontal perch. It often flicks its outer rectrices to the side "in scissor-like fashion".

In Nigeria, a bird was seen in March collecting nesting material at the base of an epiphyte. In Liberia, birds have been observed in breeding condition from June to December and independent young in September. Little else is known about this species' reproduction.

Taxonomy

Some authorities lump this species with the Rufous Flycatcher-thrush, [BirdLife International 2004.

The specific epithet honors the explorer Otto Finsch. It is often spelled "finschii", but the spelling with one "i" is correct. [del Hoyo et al. (2005), according to Lack (2006)]
