The Hawaiian Hawk or Io, (Buteo solitarius), is a raptor of the Buteo genus native to Hawai'i. For residents of the North American mainland, perhaps the most familiar buteo is the Red-tailed Hawk. Buteos tend to be easily recognized by their bulky bodies relative to their overall length and wingspan. The 'Io is the only hawk that occurs in 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.

This solitary hawk remains in and defends its territories year round. They nest from March through September, and usually lay only one egg. The female does the majority of sitting during the 38 days of incubation, while the male does the majority of the hunting. After the egg is hatched, the female only allows the male to visit when delivering food to the nest. The chick fledges at seven or eight weeks. Fifty to seventy percent of the nest successfully fledge young.

The 'Io usually hunts from a stationary position, but can also dive on prey from the air. It feeds on rodents, insects, small birds, and some game 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.
