Bristle-thighed Curlew

• It is the only wader in the world that loses the ability to fly while moulting: it renews all its flight feathers at once and spends several weeks on the ground on Pacific atolls, completely defenceless against introduced rats and cats.
• The young migrate alone: the adults leave Alaska weeks before the juveniles, which then cross thousands of kilometres of ocean on their own to islands they have never seen.
