Detailed study predicts Africa’s first bird extinction looming
March 2009. The Sidamo lark, confined to the Liben Plain grassland in southern Ethiopia, is critically endangered by bush encroachment, permanent settlement and agricultural conversion.
Its global range was previously estimated at 760 kms2, but in 2007-2008 available habitat covered just 35 kms2. Density estimates provided a global population estimate of 90-256 adults (possibly with a serious sex-ratio bias towards males).

Liben Lark with a population of possibly fewer than 100 birds, is widely tipped to become mainland Africa’s first recorded bird extinction, unless urgent action is taken to prevent its demise from the only area it now inhabits: a single grassy plain in southern Ethiopia: here.
