Numenius is a genus of wading birds commonly known as curlews. These birds are characterized by their long, curved bills and long legs, which help them forage for food in mudflats and wetlands. There are several species within this genus, including the Eurasian Curlew and the Whimbrel, each adapted to different habitats around the world. Curlews are known for their distinctive calls, which can often be heard in their breeding grounds. They primarily feed on invertebrates, such as worms and crustaceans, and are often found in coastal areas or grasslands. Due to habitat loss and hunting, some species of Numenius are considered threatened or endangered.
