The dolphin gull, sometimes erroneously called the red-billed gull, 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.

Despite often being called the red-billed gull in error, the dolphin gull is a distinct South American species closely tied to rocky coasts and seabird and marine-mammal colonies. It is a bold scavenger that readily feeds on intertidal invertebrates, carrion, offal, and even eggs or chicks of other seabirds. Adults show striking red bill, legs, and eye-ring against a slate-gray body.
