In summer, they have bright orangey-brown chests and bellies, while in winter they’re more greyish-brown. Their most distinctive features are their long beaks and legs, and the black and white stripes on their wings. Female Black-tailed Godwits are bigger and heavier than the males, with a noticeably longer beak (which helps the sexes to avoid competing with each other for food). They’re very similar to Bar-tailed Godwits, which breed in the Arctic. However, Black-tailed Godwits have longer legs, and Bar-tailed Godwits don’t have striped wings. As the names suggest, the tail patterns are different, too.
