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 autumn to spring, including passage
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, compare stockier birds with shorter, straight bills in estuary flocks. Winter plumage is largely grey and white, not the red suggested by the name.
