Catharacta

Catharacta is a genus of seabirds in the family Laridae, which also includes gulls and terns. The genus is known for containing large, powerful gulls that are often found in coastal and inland areas. Species within Catharacta are characterized by their robust build, hooked beaks, and often aggressive behavior, particularly when defending their territories or scavenging for food. They are opportunistic feeders, consuming fish, carrion, eggs, and even smaller birds.

The taxonomy of Catharacta has seen some revisions, with some species previously placed in this genus now sometimes classified under the genus Stercorarius, which also includes skuas. However, Catharacta is still commonly used for certain large gull species. These birds are widely distributed across various continents, with breeding grounds often in colder climates and migratory patterns that can take them to warmer waters. Their intelligence and adaptability have contributed to their success in diverse environments.
