The forest exploitation has been shown to increase the nest predation rates mainly in temperate climates, but there is no such a clear support for this hypothesis in tropical forests. In this study we examined nest predation in logged and unlogged site in dry deciduous forest of Kirindy (Madagascar) at the end of dry season. Nests in the canopy may suffer from different proportion of predation or type of predator than ground nests. The important effect on nest survival was found for the forest type and nest type. Both canopy and ground nests were preyed upon more often in logged forest, but the effect was more significant for terrestrial nests. The overall percentage of predation was almost 50 % higher in the site with logging history. The most abundant predators in both types of forest were birds, rodents and a Narrow-striped mongoose (Mungotictis decemlineata). The most significant effect for bird predation was found in ground nests, for rodent predation in canopy nests. We provide hypotheses about possible changes in predator composition and abundance linked to nest survival caused by human disturbance in unique dry seasonal forest habitat in Madagascar.
