Abstract：
:Two ground-dwelling couas species, Coquerel's Coua Coua coquereli and Giant Coua Coua gigas, live in sympatry in the dry forest of Madagascar. These birds are typically insectivorous and mainly feed at ground level. The two species differ by size but have the same morphology, suggesting they have the same physical attributes for foraging and prey capture. To test if the two species have the same foraging behaviour, and also to know how habitat disturbance due to logging could affect their foraging behaviour, I compared and analysed the foraging strategies of both species in two different dry forest habitats: unlogged and logged. The two species differed in their foraging behaviour between the two habitats, mainly by the ability to climb in the vegetation, and by the technique used by both species. Coquerel's Coua used more often gleaning and probing in the unlogged forest, while Giant Coua used lunge more often in this habitat. The giant Coua used also more often leaves as a substrate in the logged forest. Some modifications in the diet have been recorded too. These results suggest that anthropogenic disturbance of forest does influence the foraging behaviour of the terrestrial couas species living in the dry forest in Madagascar.
