Oystercatchers breed as vast mussel beds bare twice daily

Eurasian Oystercatchers (Haematopus ostralegus) were recorded here deep into chick-rearing season on 27 June. The six-metre tidal range that defines this coast exposes vast mussel beds twice daily — precisely the hunting ground these birds need to feed growing young.

Their presence carries ecological weight. These birds are in sharp decline across Britain, pushed out by coastal development and disturbance. Yet the Gaelic tradition held them in high regard, calling them gille-brìghde — the servant of Brigid — a name that speaks to how woven they once were into the fabric of coastal life here. When the tide turns again and the flats flood, it will take the whole estuary to sustain them.
