The 'Akiapōlā'au is a bright yellow bird with a black eye mask, found only in the upper elevations on the Big Island of Hawai'i. But its most distinct feature is its totally unique, uneven bill. The top of the bill is long, skinny, and curved like a sickle. Once abundant, habitat loss and disease from mosquitoes has taken a toll on the 'Akiapōlā'au population. In a race against extinction, people are working to restore habitat and control deadly invasive species to save Hawai'i’s rarest birds.More info and transcript at BirdNote.org. Want more BirdNote?
