Scolopacidae is a large family of shorebirds, or waders, which mainly includes many species known as sandpipers, but also others such as woodcocks, curlews, and snipes. Most of these species eat small invertebrates picked out of the mud or soil. There is no evidence that different lengths of bills enable multiple species to feed in the same habitat, particularly on the coast, without direct competition for food. On sandy beaches, species with different bill lengths feed on the only abundant invertebrate, such as mole crabs Emerita.
