The video is recorded from a web camera in Norway, but our own oystercatchers are at about the same stage in their nesting. Normally the clutch has three eggs, and the nest is almost unlined, simply there between the pebbles on the beach. Both adults brood and care for the chicks, perhaps the only seashore birds that feed their young. Food is sought on the shore, among the waterfront vegetation and in the shallow water that teems with invertebrates.
The chicks hatch in the first half of June here and fledge in July. Until then they can swim with their long legs in an emergency. Towards people the oystercatchers are rather cautious.
