Juan Fernandez Firecrown

Sephanoides fernandensis

Declining

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

The Juan Fernández Firecrown faces severe threats from habitat destruction caused by introduced goats and rabbits that have degraded native vegetation across Robinson Crusoe Island. Competition from introduced European honeybees reduces nectar availability, while feral cats prey on adults and nests. Climate change and extreme weather events pose additional risks to this island endemic with an extremely restricted range of less than 100 square kilometers.
