Great Crested Grebe Habitat and behaviour
The Great Crested Grebe has an interesting mating ritual. Grebes dance every time the pair meets, and the dance varies according to the circumstance. Returning to the nest is different from meeting out on the water, for instance. Most dances end in a bout of head-shaking. Huxley, Julian 1914. Proceedings of the Zoological Society', London.
