Range Description

Vanellus macropterus is known with certainty only from the island of Java, Indonesia, where it inhabited marshes and river deltas in the west (on the north coast) and the east (on the south coast). A specimen and two eggs collected in the 19th century may have derived from Sumatra, and there is an unsubstantiated claim that it occurred on Timor (at least three specimens). It was described as local and uncommon, apparently only ever encountered in scattered pairs, and has not been recorded since 1940. The fact that it was reputedly impossible to overlook suggests very strongly that it is no longer present at any site studied in recent decades by ornithologists. A series of surveys carried out between 2001 and 2012 have failed to locate any individuals, but there are several unconfirmed reports from local people in the Bekasi and Lumajuang districts (Iqbal et al. 2013). Rediscovery of the species in areas with historic records is considered unlikely (Iqbal et al. 2013). However, there are potentially suitable areas that have not been surveyed and observations from the 1920s suggest that its habitat requirements may have been less restricted than previously thought, perhaps providing some further hope for its continued existence (van Balen and Nijman 2007).Wet grassland on Belitung Island is a possible location requiring searches (Iqbal et al. 2013).
