Crested Tern

Species Name: Sterna bergii

Description: A breeding colony of Crested Terns exists on Mud Islands, where each summer about 1,500 pairs nest in a compact group. Each bird is scarcely out of pecking range of the ones adjacent to it which gives some level of protection against predatory gulls that snatch eggs and young wherever possible. They feed on small fish that are caught by diving to 5m or more. Usually seen in small flocks, terns often congregate on the rocky platforms or beach when not feeding.

Type: Bird
