Greater Crested Terns, race "cristatus", were photographed by us in Australia.

Food, Diet

Like all terns, Greater Crested Terns feed on fish, which they catch with their bills just under the surface of water in a steep high-speed dive from considerable height.

We will try to replace these noisy recordings with better ones as soon as possible.
