There is a definite pale supercilium or arch of feathers above the eye. . The male and female are the same color but the male is larger. Known as Uguisu in Japan. these birds were once called the Japanese Nightingale until it was discovered that they only sang during the daylight.

Habitat Introduced on Oahu in 1929 they are found in wetlands and upland and lowland forests of all the main islands. Not easily seen they are made present by their song or call which is far-carrying and may sound closer than they are perched.

Breeding During the breeding season the Japanese Bush Warblers make a “Hoohokekyo” sound. They prefer to nest in the cross of a tree . Nests are elliptically shaped and when possible made of blades of bamboo. Their nest will be higher or lower depending on the predator in the area.
