Buff-banded Rail
Gallirallus philippensis
It is a largely terrestrial bird the size of a small domestic chicken, with mainly brown upperparts, finely banded black and white underparts, a white eyebrow, chestnut band running from the bill round the nape, with a buff band on the breast. It utilises a range of moist or wetland habitats with low, dense vegetation for cover. It is usually quite shy but may become very tame and bold in some circumstances, such as in island resorts within the Great Barrier Reef region.
