Abstract
Distribution, breeding habits, and diet of the Hawaiian Thrush were recorded over seven years on the island of Hawaii. The range has been much reduced, with the result that today the species occupies approximately 30% of its former range, no longer being found in the Kohala Mountains or in the Kona area....Data on food preferences indicate the species subsists chiefly on fruits of native trees, when in season, and various insects. Comparison of present feeding habits with observations of earlier workers indicates that the diet has changed. This probably has been a consequence of the loss of suitable habitat at lower elevations....One of the earliest and latest daily singers in Hawaii, the Omao has a repertoire of at least three songs and a number of calls. The species exhibits courtship feeding. Five nests averaged 6.4 m from the ground; nesting materials include small twigs, leaves, grasses mosses, and fern pieces. For the first time the species was found to nest either in cavities or on protected platforms. One or two eggs, each marked with large lavender splotches, compose the clutch. Nestlings have flesh-colored skin, black down, and a bright yellow gape pattern. Time from building of the nest to fledging of the young is about 30 days, and the overall breeding season of the species extends at least from February to October.
