ロドリゲスベニノジコ Foudia flavicans

A sparrow-like weaver. The mostly yellow breeding males are distinctive, but females and non-breeding males are drab. Endemic to the remote island of Rodrigues, where it is found in remnant woodland scraps and plantations. Females and non-breeding males are similar to Red Fody, but Rodrigues Fody is smaller, with a slimmer bill. Also similar to female House Sparrow, but distinguished by the thinner bill. The call is a penetrating “chup” and the song is a high-pitched swizzling.
