Finding guide
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.
