Identificación
A sparrow-like weaver. Red-hooded breeding males are distinctive, but females and non-breeding males are drab. A Comoros endemic that is found in and adjacent to humid forest on the western three islands, and in drier, scrubby lowland habitats on Mayotte. Plumage varies across the different islands. The most distinctive birds, on Grand Comoro, have much less red on the breast than other populations. Can be very similar to Red Fody. Breeding male Red-headed Fody lacks red on the back and belly, though molting male Red Fody can match this pattern. Females and non-breeding males very similar to Red Fody, but Red-headed Fody is larger, darker, and more greenish, with a longer, slightly curved bill. Also similar to female House Sparrow, but distinguished by the more olive-green coloration and the longer bill. Calls are high, silvery notes, given in long series as a song.
