Альдабранский фуди Foudia aldabrana

A sparrow-like weaver. The mostly scarlet, yellow-bellied breeding males are distinctive, but females and non-breeding males are drab. Found in scrub, mangroves, and woodland on the island of Aldabra in the Seychelles. Similar to Red Fody, which recently reached Aldabra, and they have hybridized. Breeding males easily separated by their yellow belly. Females and non-breeding males very similar to those plumages of Red Fody, but can be cautiously separated by a stronger yellow wash, especially on the underparts and head. Calls are high, silvery notes, given in long series as a song.
