Overview

The yellow-breasted boatbill (Machaerirhynchus flaviventer) is a small avian species native to New Guinea and Far North Queensland, Australia. It belongs to the family Machaerirhynchidae and is classified as a species of least concern on the IUCN Red List.

Identification

• Size: A small bird ranging from 11 to 12.5 cm in length and weighing approximately 9–10 g.
• Plumage: Bright yellow underside extending up to the breast, contrasting with a black upper body in males and an olive upper body in females.
• Bill: A large, black, wide, and flat bill resembling a boat, with a hooked tip.
• Markings: White wing bars, a yellow stripe across the forehead, white throat area, and a long, stiff, rounded black tail that points upwards.

Habitat

This species inhabits subtropical and tropical moist forests, gallery forests, and forest edges across New Guinea and the Cape York Peninsula in North Queensland. It shows no preference for altitude and prefers high-vegetation density environments, often nesting high in the canopy.

Diet

The boatbill primarily feeds on airborne insects, earthworms, and grounded insects found near riverbanks and forest floors. Its unique bill shape allows it to forage both in the canopy and on the ground, particularly after rainfall.
