As of today, out of season, returns ~October. Earth Exhibit tracks the live conditions and flags it the moment it is on.
Each autumn large numbers of barnacle geese (Branta leucopsis) migrate to Islay and spend the winter feeding on coastal grasslands and roosting on Loch Gruinart.
The concentration at the RSPB reserve and adjacent flats provides reliable, large-scale goose gatherings and dramatic dawn and dusk flight displays.
