2012-06-08 Tipped to become mainland Africa's first recorded bird extinction – Liben Lark.
Liben Lark [ Sidamo Lark] - Heteromirafra sidamoensis - is
listed as Critically Endangered. It has an extremely small range [a single
grassy plain in southern Ethiopia]
and its range size is decreasing. The remaining habitat is rapidly being
degraded, and the number of mature individuals is decreasing [with a population
of possibly fewer than 100 birds]. The Liben Lark is tipped to become mainland Africa's first recorded bird extinction.
Liben Lark
The Liben Lark or Sidamo Lark - Heteromirafra
sidamoensis – is endemic to
Ethiopia.
Its natural habitats are dry savanna and subtropical or tropical dry lowland
grasslands.
Description
A small,
large-headed, short-tailed lark with a pale buff stripe down centre of crown. The
feathers on its back are brownish, each with a blackish centre and a cream to
white edge, resulting in a streaky appearance. The short, thin tail is browner
than the back, and the underparts are white or buff. It has a long, slender
neck and large head, with a pale buff stripe running down the centre of the
crown. The bill is pale yellowish and the legs are pale brown to pinkish. The
sexes are similar.
Call
It calls with a
series of melodic, clipped whistles, typically heard as it flies high in the
air.
Food
This larks diet consists
of invertebrates, plant matter and seeds.
Breeding
The nest is a
grass bowl on the ground.
Conservation Status – Critically Endangered
Its occurrence in
just one small region, in which there are no protected areas, makes
the Liben lark highly vulnerable to any threats. Currently, the greatest
threat appears to be the loss of its habitat.
A lifeline to
prevent Africa's first recorded bird
extinction.
This globally threatened bird has now been thrown a lifeline thanks to funds
raised, £242,000 (US$395,000) by the British Birdwatching Fair held at Rutland
Water August 2010. These funds will be used by the Ethiopian Wildlife and
Natural History Society, the BirdLife Partner in the country, to work with
local communities to reduce the impact of over-grazing livestock and prevent
conversion of the land to arable farming. Helping the grasslands recover will
benefit both the lark and the local inhabitants.
