Résumé :	On upland Mauritius, an endemic and an introduced species of fody Foudia (weavers Ploceidae) breed sympatrically and simultaneously: the Mauritius Fody F. rubra and Madagascar Fody F. madagascariensis. The nests of the two species are similar in most respects. However, in both architecture (thick walls and copious lining) and material thigh proportion of apparently rot-resistant materials), the nest of the endemic species seems better suited to the cool, very wet, local climate. Madagascar Fodies' nests in the same area lack an inner lining, have thin walls and are composed of a limited selection of materials, the choice of which seems relatively undiscerning. A possible explanation for this difference is suggested. Both species build an outer roofing layer on top of their nests, which has not been fully documented before, is unknown in other genera and may be a waterproofing layer.
