The godwits are a group of large, long-billed, long-legged and strongly migratory waders of the bird genus Limosa. Their long bills allow them to probe deeply in the sand for aquatic worms and molluscs. They frequent tidal shorelines, breeding in northern climates in summer and migrating south in winter. In their winter range, they flock together where food is plentiful. A female bar-tailed godwit holds the record for the longest non-stop flight for a land bird.
