The Javan woodcock (Scolopax saturata) or rufous woodcock is a small wader restricted to wet mountain forests on Sumatra and western Java. It nests on a bed of moss in light undergrowth. It has a "drumming" display flight like the Eurasian woodcock, but the calls are different.[citation needed]
Numbers of the species are currently decresing, and the current population is estimated at between 2500 and 10,000 adults, split across between ten and fifty subpopulations. One generation usually spans a little over four years.[1]
