The Hawaiian Hawk or 'Io, Buteo solitarius, is a raptor of the Buteo genus endemic to Hawai'i. Buteos tend to be easily recognized by their bulky bodies relative to their overall length and wingspan. The 'Io is the only hawk that is native to Hawaii, where they are only known to breed on the Big Island in stands of native `ohi'a lehua trees. The species is protected as Endangered in the United States. However, the IUCN classifies the species as Near Threatened.
The 'Io usually hunts from a stationary position, but can also dive on prey from the air. It feeds on rats, small birds, stream animals, crickets, praying mantises, millipedes, centipedes, and occasionally the worm. It will also feed on the Hawaiian Crow, another one of Hawaii's endangered birds. They are opportunistic predators and are versatile in their feeding habits. They have a shrill and high-pitched call much like their Hawaiian name: "eeeh-oh." They are known to be very noisy during the breeding season. 'Io are strong fliers.
