Photographic evidence of bi-parental nest-building by Schlegel's Asity Philepitta schlegeli (Philepittidae)

The reproductive systems and nesting biology of the four species of the Madagascar-endemic Philepittidae are poorly known. Some are described as polygynous, with males forming leks, but without supporting evidence. Our photographs show bi-parental nest-building by two pairs of Schlegel's Asity Philepitta schlegeli, suggestive of social monogamy. We review and briefly assess reports on the reproductive strategy and nesting biology of all four species of Philepittidae.
