Oahu ʻElepaio
Chasiempis ibidisAlso known as Oahu Elepaio, Oahu Flycatcher
Oʻahu ʻElepaio are curious, territorial monarch flycatchers that actively defend their home ranges year-round in mesic and wet native forests. Adults forage acrobatically by snatching insects from leaves, twigs, and mid-air, frequently investigating hikers who pass through their territory. Nesting high in forest canopy trees, pairs suffer severe pressures from introduced predators and mosquito-borne diseases, making ongoing habitat management vital to their survival.

- Support conservation
- Observe strictly from marked public trails, avoid using broadcast playback calls, and never disturb active nest sites.
Responsible observation
- Listen for Calls: Search high-elevation forest trails on Oʻahu while listening for their distinct whistling whistle.
- Maintain Distance: Give foraging birds ample space to avoid disturbing their natural behavior and nesting sites.
- Stay on Trails: Protect fragile native Hawaiian forest understory by sticking strictly to designated paths.
