The long-tailed honey buzzard (Henicopernis longicauda) is a bird of prey in the family Accipitridae. It is found in New Guinea and some neighboring island groups. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest.
The Long-tailed honey buzzard is described as having a thin body, small head, long rounded tail and wide, round wings. They fly with their wrists forward while spreading their characteristically "fingered" primary feathers. The wing and tail feathers have dark black barring. The face and bill are pale and the iris is yellow. The head and breast feathers are lightly streaked. The total length, including the tail feathers, is reported to be from 50–61 cm (22 in). The wingspan ranges from 105–140 cm (48 in). The tail feather length ranges from 29–37 cm (13 in). The size of males as a proportion of the size of females was calculated to be 89%. The males weigh 447–630 grams and the larger females weigh 570–730 grams. Adults can be identified by their three visible boldly black bars on the body and wings, while the fourth bar is hidden. They have bluish-white feet. Juveniles can be identified... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Long-tailed Honey-buzzard is recorded against all the birds logged in Raja Ampat (108 verified sightings from 2019 to 2026), calibrated against known sighting rates.
