The '''sociable lapwing''' or '''sociable plover''' (''Vanellus gregarius'') is a critically endangered [[wader]] in the [[lapwing]] family of [[bird]]s. The genus name is [[Medieval Latin]] for a [[northern lapwing|lapwing]] and derives from ''vannus'' a [[Winnowing#In Greek culture|winnowing fan]]. The specific ''gregarius'' is [[Latin]] for "sociable" from ''grex, gregis'', "flock".<ref name=job>{{cite book | last= Jobling | first= James A | year= 2010| title= The Helm Dictionary of Scientific Bird Names | publisher=Christopher Helm | location = London | isbn = 978-1-4081-2501-4 | pages=178, 397}}</ref>

==Description==
This medium-sized lapwing has longish black legs and a short black bill. Summer adults have grey backs and breast, dark belly and white undertail. The head has a striking pattern, with a black crown and eyestripe, the latter being bordered above and below with white. The upper neck is ochre. Its longish black legs, white tail with a black terminal band and distinctive brown, white and grey wings make it almost unmistakable in flight. Length is {{convert|27|–|30|cm|in|abbr=on}}. The call is a harsh ''kereck''.

Winter adults have a less distinct head pattern, slightly browner back and breast, and white belly. Young birds have a scaly back and only traces of the head pattern.

==Range and breeding==
This species breeds on open grassland in [[Russia]] and [[Kazakhstan]]. Three to four eggs are laid in a ground nest. These birds [[bird migration|migrate]] south through [[Kyrgyzstan]], [[Tajikistan]], [[Uzbekistan]], [[Turkmenistan]], [[Afghanistan]], [[Armenia]], [[Iran]], [[Iraq]], [[Saudi Arabia]], [[Syria]] and [[Turkey]], to key wintering sites in [[Israel]], [[Syria]], [[Eritrea]], [[Sudan]] and north-west [[India]]. Birds winter occasionally in [[Pakistan]], [[Sri Lanka]] and [[Oman]]. It is a very rare vagrant in western and northern [[Europe]], where this gregarious bird is usually found with [[northern lapwing]]s. It feeds in a similar way, picking [[insect]]s and other small prey mainly from grassland or arable land.

==Status==
In 2004, [[BirdLife International]] categorised this bird as critically endangered, due to a very rapid population decline for poorly understood reasons. The main decline took place between 1960 and 1987, when the known population halved; it is some 20–25% of the 1930s population levels.<ref name=BirdLifeFactsheet/> The current population was estimated to be between 600 and 1,800 mature birds in 2006,<ref name=BirdLifeFactsheet/> but is being revised to the upward end of that scale, possibly more, following the discovery of the species' previously unknown main wintering grounds in [[Syria]], where 1500 birds of all ages were encountered.<ref name=BirdLife/> Additionally, in October 2007, a superflock of approximately 3,200 sociable lapwings were discovered in Turkey, according to Guven Eken, director of the Turkish Nature Association.<ref name=npr/> The current [[IUCN]] classification is '''CR A3bc'''—meaning that the population is expected to decline in the next decade or so by 80%, but based on theoretical considerations and the known [[habitat destruction]] rather than direct observation of the birds. Thus, the new discoveries might mean that as more data becomes available, the species could be downlisted to [[Endangered]].
