Summary
Provide artificial nesting sites for ground and tree-nesting seabirds
A replicated, site comparison study in 2013–2014 on Cousine Island, Seychelles (Hart et al. 2016) found that breeding success of white terns Gygis alba was higher in artificial coconut-shell nests than natural nests. Fledglings were produced from 60% of artificial nests, vs only 32% of natural nests. Artificial nests also had higher hatching success (65% of eggs hatched) and fledging success (92% of chicks fledged) compared to natural nests (hatching: 52%; fledging: 61%; statistical significance not assessed). Artificial nests were cleaned, smoothed coconut husks nailed to tree branches. Twenty artificial nests and 113 natural white tern nests were monitored weekly between March 2013 and December 2014. This study was on the same island as (Fujita et al. 2009), but it is not clear if the same nests were monitored.
