Provide artificial nesting sites for wildfowl
A replicated study in Australia (Norman & Riggert 1977), found that wildfowl in Western Australia used only 1% of 1,999 artificial nests in 1974, whereas 36% of 2,440 artificial nests in Victoria were used in 1975-6. The majority of records from Victoria were of chestnut teal Anas castanea, which are uncommon in Western Australia. All Western Australian nests were made from plastic drums and erected at 23 wetland sites in 1969-74; Victorian nests were made from various wooden and metal boxes and plastic drums and were erected at 26 wetland sites between 1975-6. All nests were attached to poles and trees at heights of up to 3.6 m. Nests below 50 cm off the ground were mostly avoided by birds.
