Bar-tailed Godwit (Limosa lapponica) Kūaka in Maori is a large wader . It makes the longest known non-stop flight of any bird and also the longest journey without pausing to feed by any animal, 11,680 kilometres along a route from Alaska to Zealand. The Bar-tailed Godwit is a relatively short-legged species of godwit. The bill-to-tail length is 37–41 cm, with a wingspan of 70–80 cm. The adult has blue-grey legs and a very long dark bill with a slight upward curve and pink at the tip. The neck, breast and belly are unbroken brick red in breeding plumage, off white in winter. The back is mottled grey. It eats mainly insects and crustaceans as well as parts of aquatic plants.
