Amazing watching these waders flight back and forth with sea shell fish, heads looking down with beaks probing the sand for any movement or sound. They have to be careful because the Black headed Gull and Herring Gull waits for them to find food then ram raids it for the food. There anther bird when on the water egde will only tolerate human presence up to a certain distance.
The way I get close is to use the sea defence wood barriers that go fro the prom wall out to sea. I wait till low tide and find s spot where there is plenty of rocks and shells. They wait for the tide to come in and wash up the shells that are burried.
