Red
List Category & Criteria: CR A3bc ver 3.1 (2001)
Year Assessed:
2006, Assessor/s: BirdLife International
Evaluator/s: Butchart, S. & Pilgrim, J. (BirdLife International
Red List Authority)
Justification: This species is listed as Critically Endangered
because its very small population has undergone
an very rapid reduction for poorly understood reasons, and
this decline is projected to continue
and increase in the future.
Recent fieldwork in Kazakhstan (and counts in Turkey and
the Middle East) has shown the population to be
substantially larger than previously feared, and further research
may show that the species warrants
downlisting to a lower category of threat.

Identification
27-30 cm. Large, strikingly patterned plover. Adult greyish with
black and chestnut belly. White supercilium and black crown and
eye-stripe. Winter adult brownish but retains supercilium and crown
pattern. Juvenile brown, slightly scalloped above, and streaked
black below with large white supercilium.
Population estimate
600 - 1,800 (2.500-3.000 Rare Birds Yearbook
2008)
decreasing
Range estimate (breeding/resident) 1,927,000 km2
The Sociable Lapwing,
Vanellus gregarius, breeds in Russia and Kazakhstan, dispersing
through
Kyrgyzstan, Tajikistan, Uzbekistan, Turkmenistan, Afghanistan, Armenia,
Iran, Iraq, Saudi Arabia,
Syria and Turkey, to key wintering sites in Israel, Eritrea, Sudan
and north-west India.
Birds winter occasionally in Pakistan, Sri Lanka and Oman.

It has suffered a very rapid decline and range contraction.
In northern Kazakhstan, a decline of 40% between 1930-1960, was
followed by a further halving of numbers between 1960-1987. These
declines have continued, or even accelerated,
to the point that the current population is estimated to be only
600-1,800 individuals.
It has a sporadic and irruptive pattern of semi-colonial breeding,
mainly in the transition zones
between Stipa and Artemisia grassland steppes where bare saline
areas occur near water-bodies.

Exact breeding habitat requirements are poorly known. It has recently
been postulated that it evolved
to nest in the short swards left in the wake of enormous wintering
herds of saiga Saiga tartarica.
The wintering grounds are dry plains, sandy wastes and short grass
areas, often adjacent to water.
Threats Key factors
explaining the magnitude of recent declines remain unknown.
On the breeding grounds, it is threatened by the conversion of steppe
to arable cultivation,
but large areas of apparently suitable breeding habitat are unoccupied.
The species habitat may however have been altered by a reduction
in grazing by large herds
of native ungulates and, latterly, by the loss of the enormous herds
of domestic grazing animals
from state-sponsored collective farms.

Breeding may now only occur in vicinity of villages which exposes
birds to additional threats,
such as predation by dogs and cats, and human disturbance.
Many colonies are destroyed during agricultural operations or are
predated by
Rook Corvus frugilegus, which have increased considerably in breeding
regions.
Nests in grazed areas may suffer from trampling. It may also have
been adversely affected by the increasingly dry climate in its breeding
and wintering range.

Huge Flock Of Critically
Endangered Sociable Lapwings Discovered
ScienceDaily (Oct. 23, 2007)
Hopes are rising for one of the worlds rarest birds
after the discovery of the largest flock seen for more than
100 years.
More than 3,000 critically endangered sociable lapwings have
been found in the Ceylanpinar district of south-eastern
Turkey after a satellite tag was fitted to one of the birds
migrating
from breeding grounds in Kazakhstan.
The tracked lapwing had flown more than 2,000
miles from its nesting site, where numbers of the species
have plunged
following the collapse of Soviet farming. The bird flew north
of the Caspian Sea, then down through the Caucasus
and south into Turkey.
Only 200 pairs of sociable lapwing were
thought to remain in 2003 when the bird was classified as
critically endangered,
the highest level of threat there is.
