These waders are normally found all along the edges of water. They have a very loud and distinctive piping call in flight, a continuous 'k-peep k-peep k-peep'. You will often hear an oystercatcher before you see it. Their visible appearance is easily identified - black and white with a long bright orange bill (a magpie eating a carrot). They feed by probing the mud, or poking around in rock pools. They can open shellfish with their strong bills. These were seen on the beach, over the sea and on the pools.
