Actitis Hypoleucos is a scientific name for a bird species commonly known as the Common Sandpiper. However, there are several synonyms used to refer to this species which include Tringa Hypoleucos, Totanus Hypoleucos, and Helodromas Hypoleucos. Common Sandpipers are medium-sized birds that typically breed around freshwater sources and migrate to coastal areas during the winter season. Their distinctive characteristics include striking white underparts that contrast with their brown upperparts, and a habit of bobbing their tails whilst walking on pebbly shores or mudflats. The versatility of sandpipers makes them an essential component of many aquatic ecosystems.
