Baby great horned owls at Hull's Gulch
Neighbor took this picture on his way to work in our subdivision.
This graceful bird of prey measures 16 to 18 inches in length, the female being larger. Two color phases exist: a dark phase (dark brown head, breast, and underwings), and a light color phase (dark head, light breast and light underwings). Feet and legs are yellowish in adults and greenish in immatures.
The ‘io is endemic to Hawai‘i and was a symbol of royalty in Hawaiian legend. The ‘io is also the only hawk today native to Hawai‘i. They only breed on the Big Island but have been occasionally seen on Maui, O‘ahu, and Kaua‘i. Fossil records indicate that this hawk may also been established on Moloka‘i and Kaua‘i. They depend on native forest for nesting, but are able to use a broad range of habitats for foraging, including papaya and macadamia nut orchards, as well as forests dominated by native and introduced vegetation, from sea level to 6,500 feet elevation.
This mostly 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.
Koa trees are the tallest and the second most abundant endemic tree in the Hawaiian forest. The largest Koa trees are possibly the last remaining old growth trees in Hawaii, spared from logging and clear cutting for cattle ranching. The smaller koa can sprout from roots of nearby older koa and spread by seeds. Light gaps in the forest are perfect for this sun-loving species. Koa means "brave" and "bold" and "valiant", as well as "warrior", in Hawaiian. A very hard wood used for making weapons, surfboards, and canoes. In Hawaiian culture, it is said that if an ʻelepaio bird is found pecking on the trunk of a potential Koa, the canoe builder would pass it by knowing it was insect infected and so not a good choice.
