The Javan lapwing (Vanellus macropterus) also known as Javanese lapwing and Javanese wattled lapwing is (or was) a wader in the lapwing family. This large, long-legged wader inhabited the marshes and river deltas of Java, and possibly Sumatra and Timor. It was last seen in 1940, and as it was a conspicuous species unlikely to be overlooked, it seems likely that it is extinct. And the IUCN classified it as such in their 1994 and 1996 assessments, but reversed that in 2000 and listed the species as Critically Endangered (CR).
