Bonin White-eye

The Bonin white-eye is 12 to 14 cm (4.7–5.5 in) long and weighs around 15 g (0.53 oz). The nominate race has a yellow head with a conspicuous triangular black eye-patch which is linked by the thin black line to a black forehead. The white eye-ring is broken by a thin black line through the eye. The lores are yellow, as are the throat and upper breast. The back and wings are olive-green tinged with grey, and the primaries are tinged with brown. The tail is olive-brown, and the underparts are pale yellow, with a grey wash on the flanks. Voice: The Bonin white-eye was long thought to be an infrequent songster. Early accounts reported no singing from captive birds, and a report published in 1985 noted that while it did sing, it did so very irregularly. The same report concluded that the species did not use its call for territorial defence.
