Provide artificial nesting sites for wildfowl
A replicated one-year study in 2001 in Sumatra, Indonesia (Drilling 2001), found that no white-winged ducks Cairina scutulata were observed entering any of 25 nest boxes erected in trees in a swamp forest site. Boxes were 53 x 43 x 41-48 cm, with a 20 x 17cm entrance hole and four drainage holes, and were erected 1.5-4.0 m above the ground (mainly in durian trees Durio zibethinus). The author argues that nest boxes may take several years to be accepted and so may be used in the future.
