Noronha Elaenia Elaenia ridleyana is a passerine endemic to Fernando de Noronha, more than 350 km off north-east Brazil. It occurs on only three of the 26 islands in the archipelago. However, a single individual was photographed on 16 June 2021 on Atol das Rocas, 145 km west of Fernando de Noronha. Long-distance movement of Noronha Elaenia raises questions on whether this species could reach the mainland and if it is a valid species.
