The dolphin gull (Leucophaeus scoresbii), sometimes erroneously called the red-billed gull (a somewhat similar but unrelated species from New Zealand), is a gull native to southern Chile and Argentina, and the Falkland Islands. It is a coastal bird inhabiting rocky, muddy and sandy shores and is often found around seabird colonies. They have greyish feathers, and the feathers on their wings are a darker shade. Dolphin gulls have a varied diet, eating many things ranging from mussels to carrion. The modern scientific name Leucophaeus scoresbii, together with the obsolete common name Scoresby's gull, commemorates the English explorer William Scoresby (1789–1857). Wikipedia →
