Finding guide

Habitat first

Choose the season, find the habitat, then watch patiently. Search guidance is not a measure of rarity or conservation status.

When to go
All year
Where to start
Safe coastal paths, harbours and rocky shores exposed at low tide.
What to do when you arrive
From public rocky-shore and harbour paths, scan inshore water and rocks. White wing patches stand out in summer; winter plumage is paler. Do not inspect crevices.
