Hawai'i Akepa
Akepa is unique among Hawai'i's birds. Endemic to the island of Hawai'i.It also has developed a highly unusual bill. It's lower bill curves to one side, making it asymmetric. This helps it to pry open buds to snare the insects within.
Threats to this beautiful bird's survival comes from mosquito-born avian diseases, pigs, nest prdation by rats, and introduced yellow jackets and ants, which compete with it for prey.
