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
Most accessible in autumn and winter; also breeds locally
Where to start
Estuary paths and hides overlooking tidal flats; do not flush roosting flocks.
What to do when you arrive
In autumn and winter, scan small estuary waders and compare slightly downcurved bills. Winter birds lack the summer black belly patch; do not scatter the flock.
