Introduction

The Comoro Fody was formally described by Charles Lucien Bonaparte, a French biologist and ornithologist. Around 1849 Bonaparte began work on preparing a classification of all the birds in the world, visiting museums across Europe to study the collections. In 1850, he published the first volume of his Conspectus Generum Avium which included 3 weavers. Bonaparte studied the type specimen of the Comoro Fody in the Paris Museum.The Comoro Fody was collected by Loius Rosseau. Rousseau travelled the western Indian Ocean on the French naval corvettes Prevoyante and Dordogne in 1839-1841. The Prevoyante visited Mayotte in 1840 and 1841 and the Dordogne visited Mayotte and Zanzibar at least in 1840 (Cheke 2011). The Comoro Fody may have been introduced to Zanzibar, and then collected there by Rousseau, or Rousseau mis-labelled his specimen.

The Comoro Fody differs slightly in measurements and plumage on the different islands of the Comores, and Benson (1960) showed that the type specimen matches the subspecies on Moheli Island.

The first illustration of a Comoro Fody is by Verreaux (1867) of the nominate subspecies. The next illustration was published the following year by Pollen (1868), but of subspecies algondae. Reichenbach (1863) mentioned the species, and provided an English name, but did not illustrate it.

1. Basic biology

Identification. The Comoro Fody, or Red-headed Forest Fody, Foudia eminentissima breeding male has a red head, breast and rump. It is distinguished from the introduced Madagascar Fody by having larger and longer bills, and clearer wing bars.

Distribution. The Comoro Fody is found on the Comoro Islands (see map above, based on Birds of the Malagasy region). There are 4 subspecies, found on different islands:
F. e. eminentissima on Moheli (Mwali) Island (see red on map).
F. e. consobrina, on Grand Comoro (Njazidja) Island (see yellow on map). This race is smaller and more slender-billed than the nominate, greyer below, and overall more orange than red.
F. e. anjuanensis , on Anjouan (Ndzuani) Island (see green on map). This race is orange on the head and rump, the orange often extending to the belly, and has an orange wash on the mantle.
F. e. algondae , on Mayotte (Maore) Island (see orange on map). This race is smaller than the nominate, and dorsally is greener and plain-coloured.
These races may represent more than one species. The Aldabra Fody is no longer considered a race of this species.

Habitat. The Comoro Fody inhabits well wooded habitats and forested areas. On Mayotte it is not found in intact stands of evergreen forest. On Grand Comoro, Mohéli and Mayotte it is found close to sea-level.

Food. The diet of the Comoro Fody is mainly insects, including beetles, grasshoppers, and ant pupae. The Comoro Fody also feeds on fruit and spiders.

Breeding. The Comoro Fody is probably monogamous. It is territorial, and males sing from tree tops in their territories. The nest is globular with a side entrance near the top. There is usually a porch above the entrance. Nests may have a ceiling of moss.

The eggs (clutch of 3) are pale blue, with a few fine spots. Possible nest predators include the exotic black rat, lemurs, and raptors.
