Dusky Tetraka Xanthomixis tenebrosa Scientific name definitions

NE Madagascar, from at least Marojejy S to Zahamena. Few reliable records since 1930. Reports from Masoala Peninsula, Analamazaotra and Ranomafana National Park require confirmation (2 Safford, R.J. and Hawkins, A.F.A. eds. (2013). The Birds of Africa. Vol. 8. The Malagasy region. Christopher Helm, London. Close ).

VULNERABLE. Restricted-range species: present in East Malagasy Wet Forests EBA. Global population estimated to number fewer than 10,000 individuals. Clearly rare and local, as numerous recent intensive surveys in many forests of E Madagascar, covering wide range of habitats and altitudes, have failed to locate it. Enigmatic; has been widely misidentified in the past, since key identification criteria only recently determined and still poorly understood. Only recent documented records are from Marojejy and Zahamena National Parks; reported also from Masaola, Perinet Special Reserve and Maroantsetra, but without details. Earlier specimen records from elsewhere, including the Andasibe-Mantadia region, but precise localities and altitudes are not known. Outside protected areas, main threats are from forest clearance for subsistence agriculture, which is most prevalent at altitudes at which present species is known to occur.
