Abstract

We carried out an artificial nest experiment to investigate differences in predation rates of bird nests among different habitats and to identify predators on Kikai Island, in the Amami Island group. Both the proportion of depredated nests and the probability of survival showed that nests in forests suffered predation more frequently than nests in bushes and grasslands. Artificial nests with automatic image recording systems revealed that two introduced mammals (i.e., Black rat Rattus rattus and Japanese Weasel Mustela itatsi) and the indigenous Jungle Crow Corvus macrorhynchos were predators. Neither the degree of concealment of individual nests nor the distance between nests was found to have a significant relationship with predation. It is possible that frequent nest predation in forests results from the abundance and habits of each predator species.
