Abstract

The behavior and parental care of the endemic Red-tailed Vanga Calicalicus madagascariensis were studied in Ranomafana National Park, south-eastern Madagascar, from December 2007 to January 2008. Both sexes are similar in size, but show striking plumage-color dimorphism. The studied breeding pair shared duties in nest building, egg incubation and care of the young, but the male provided more parental care than the female. No helpers were observed at the nest during the study. Incubation lasted about 24 days and the nestling period was 15 days during which time chicks were fed on different types of insects and arthropods (mainly butterflies, spiders and locusts) obtained from the systematic inspection of the branches and leaves. The extensive male investment in the breeding might be due to ensure high rates of nestling growth and to avoid nest predation. To conclude, Red-tailed vanga is a socially monogamous species that exhibits classic biparental care.
