The Pelengdrossel ( Geokichla mendeni ) is a little researched songbird species from the genus Geokichla . It occurs on Peleng in the Banggai Archipelago and on Taliabu in the Sula Archipelago . However, the individuals of Taliabu could also represent a previously undescribed subspecies. The art epithet honors the Dutch animal collector and taxidermist Johannes J. Menden.
features
The Pelengdrossel reaches a size of 20 cm. The top, from the forehead to the upper rump, is reddish-cinnamon in color. In the birds of Taliabu, the under-tail-coverts also have a reddish-cinnamon color. The rest of the body is black, except for a large, oval, white spot on the ear covers. The beak is slate-colored. The legs are flesh pink. The sexes are likely to be similar. The juvenile birds have not yet been described. The call consists of a thin, high, ascending note; the singing consists of a fluid series of notes.
Habitat and way of life
On Taliabu, the peleng's thrush lives in lowland forests at altitudes of 50 to 300 m, including selectively cut and degraded forests with bamboo stocks. It usually goes in search of food individually or in pairs. Their diet consists of arthropods and mollusks that are found on the ground. Nothing is known about their reproductive behavior.
Systematics
The Pelengdrossel was first described by Oscar Neumann as Turdus (Geokichla) mendeni in 1939 . In 1943 it was classified by John Todd Zimmer and Ernst Mayr as the subspecies Geokichla erythronota mendeni of the red-backed thrush. In 1952 the Pelengian Thrush was listed by S. Dillon Ripley as Zoothera erythronata mendeni . In 2004 it was split off from Nigel Collar as an independent species, Zoothera mendeni . In 2008 Gary Voelker and John Klicka transferred the Pelengdrossel to the genus Geokichla , which for a time was considered a subgenus of Zoothera .
status
The IUCN lists the Pelengdrossel on the early warning list ( near threatened ). Of Peleng, the species is only known from the type specimen collected by Johannes J. Menden in August 1938. During a 1991 field study on Taliabu, the pelengue was sighted a number of times. Here their habitat is quite extensive, but mostly includes secondary forests.
