Finding guide

Season first

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

When to go
Mainly spring to autumn
Where to start
Safe public harbour walls and coastal viewpoints.
What to do when you arrive
In spring and summer, watch pointed-winged birds plunge-diving from public shorelines. Compare bill colour and proportions with Arctic Tern, staying away from nesting platforms.
