Use artificial nests that discourage predation
A replicated trial in woodland on Rhode Island, USA, in 1955-56 (Cronan 1957), found that installing predator guards on wood duck Aix sponsa nest boxes reduced the usage of nest boxes, compared to unguarded nest boxes, when birds were given a choice of boxes (55% of 40 boxes with guards used vs. 93% of 40 unguarded boxes). However, in areas where all boxes were either guarded or unguarded, there was no significant difference in usage (51% of 55 guarded nests used vs. 56% of 52 unguarded). This study is also discussed in ‘Provide artificial nesting sites’.

Provide artificial nesting sites for wildfowl
A replicated trial in 20 woodland sites on Rhode Island, USA, in 1955-56 (Cronan 1957) found that wood ducks Aix sponsa used 36-100% of nest boxes installed in study areas. A total of 102 nest boxes were observed in 1955 and 85 in 1956. This study is discussed in more detail in ‘Use artificial nests that discourage predation’.
