The family Vangidae is monophyly group of species which underwent extensive in situ radiation within Madagascar. Although the foraging ecology and the phylogeny of this family have been studied, basic information on the breeding biology of each species is poorly known. We described the breeding ecology of Van Dam's Vanga Xenopirostris damii, which is endemic to Madagascar, and considered the mating system of this species. The research was conducted at Ampijoroa Forest Station in the Ankarafantsika Strict Nature Reserve during October to November in 2000. Six pairs were observed in the study area. Each pair had home range which did not overlapped with each other. No interaction was observed among pairs. Parental activities in nest building, incubation and nestling stages were observed at three nests. Both sexes participated in these activities, and no helpers were observed. The non-overlapping home ranges and biparental care suggest that the mating system of Van Dam's Vanga is socially monogamy.
