About the Northern Gannet

The Northern Gannet (Morus bassanus) is a large seabird known for its striking appearance, impressive diving ability, and colony-based breeding habits. The Northern Gannet is one of the largest seabirds in the North Atlantic, with a wingspan of up to 2 meters and a body length of about 90-100 cm.

Adults are predominantly white with black-tipped wings and a yellowish head. Their long, pointed beak is pale blue-grey with a black outline. Juveniles are mottled brown and white and gradually acquire adult plumage over several years.

The northern gannet is endemic to the North Atlantic and most breed in Britain and Ireland. There are 21 gannetries around Britain and Ireland, with most being on remote offshore islands and stacks, and two on mainland cliffs. Some colonies have been occupied for centuries and are large and conspicuous.

Despite their stable population, they face threats from oil spills, plastic pollution, overfishing (which reduces their food supply), and climate change, which affect their marine environment.

Rising sea levels can lead to the loss of coastal nesting sites. Many Northern Gannet colonies are located on low-lying islands and cliffs vulnerable to erosion and submersion.

Increased storm activity due to climate change can destroy nests and cause chick mortality. Severe weather can also make foraging more difficult and dangerous for adult gannets.
