- Habitat loss
The Oahu Elepaio is a native monarch flycatcher that only lives on Oahu Island of Hawaii. It bears striking similarities to the Hawaii Elepaio except for its more rust-coloured head and a more distinct white pigment all over its breast, flanks, and underside.
More than half of the Oahu Elepaio’s natural range has already been destroyed to give way to urban development and agricultural purposes. One of the most serious issues it is facing is the threat from black rats that ransack the nests and feed on eggs and young birds alike. The remaining population is also susceptible to mosquito-borne diseases such as malaria and avian pox.
