Bristle-thighed Curlew
Numenius tahitiensis
The bristle-thighed curlew has a long, decurved bill and bristled feathers at the base of the legs. Its length is about 40–44 cm (16–17 in) and wingspan about 84 cm (33 in) (females averaging bigger than males). The size and shape are the same as the whimbrel's, and the plumage is similar, spotted brown on their upper body with a light belly and rust-colored or buffy tail. The bigger buff spots on the upper body, unmarked light belly and barely marked flanks, tail color, and pale buffy-orange rump distinguish it from both whimbrels.
