Vulnerable (Collar et al., 2000). The Philippine Duck, locally known as the 'papan' has declined dramatically throughout the Philippines, largely due to hunting and loss of its wetland habitat; its population is thought to have decreased by over 20% in just 10 years. Small numbers of 'papan' were sighted throughout the Polillo Islands however Jomalig Island represents its true stronghold, with a renowned breeding population and numbers estimated at 3000 (Gonzalez, J.C.T., 1997) - a site of global significance. Our surveys documented a maximum of 50 individuals instantaneously with such sightings typically occurring around pools of fresh and brackish water; these areas of standing water lie within a matrix of rice paddies, rough pasture and marshland. Recent television coverage of the Jomalig's 'Papan' has generated enthusiasm for its protection however it continues to be perceived as a pest of the rice paddies and nestlings are also collected. Attention was drawn to the need for effective anti-depredatory devices.
