Overview
The Gannet is a spectacular seabird and one of the most visible from the Sefton Coast beach. Large, white with a yellow-buff head and black wingtips, they cruise offshore and then plunge-dive at up to 100 km/h into the sea. The UK hosts 60% of the world population — mainly on island colonies in Scotland and Wales. In autumn, post-breeding dispersal brings large numbers past the Sefton Coast, and watching from Formby Point during a northwest gale can produce hundreds in a day.

Where to See It
Offshore from Formby Point and Ainsdale beach. Also visible from the top of the dunes on a clear day. Most spectacular during northwest storms.
Identification
Very large seabird. White with black wingtips and yellow-buff head. Long, pointed wings. Characteristic plunge dive from height. Juvenile dark brown, gradually whitening over 5 years.
Viewing & Photography Tips
Sit on the dune at Formby Point and scan offshore. Gannets are visible at considerable distance. Northwest gales push them closer to shore. A telescope is useful but not essential.
Conservation Status
UK Amber List
This species is on the UK Amber List for Birds (BoCC5), indicating moderate concern. Population monitoring and habitat management remain important for its continued recovery.
Frequently Asked Questions
How fast does a Gannet dive?
Gannets reach speeds of up to 100 km/h during their plunge-dives. Specialised adaptations include air sacs under the skin of the face and chest that cushion the impact, forward-facing eyes for binocular vision to judge distance, and nostrils that open inside the bill rather than externally, preventing water from entering. They can dive to depths of 22 metres after plunging.
