Knob-billed fruit-dove Ptilinopus insolitus

A unique fruit dove with a diagnostic combination of a large red knob above the bill, a large orange belly patch, and gray shoulder spots. Restricted to lowland forest, particularly secondary and degraded forest patches, where it often perches in the open but is deceptively well camouflaged. Could potentially be mistaken for Red-knobbed Imperial-Pigeon, but is much smaller, with a bright green body. Voice is little known, but sometimes gives a drawn-out, four-noted “whooOOoo-hu-ooo-huu.”
