Behaviour
The Great Crested Grebe has an elaborate mating display. Like all grebes, it nests on the water's edge, since its legs are set relatively far back and it is thus unable to walk very well. Usually two eggs are laid, and the fluffy, striped young grebe are often carried on the adult's back. In a clutch of two or more hatchlings, male and female grebes will each identify their 'favourites', which they alone will care for and teach
Unusually, young grebes are capable of swimming and diving almost at hatching. The adults teach these skills to their young by carrying them on their back and diving, leaving the chicks to float on the surface; they then re-emerge a few feet away so that the chicks may swim back onto them.
The Crested Grebe feeds mainly on fish, but also small crustaceans, insects and small frogs.
This species was hunted almost to extinction in the United Kingdom in the 19th century for its head plumes, which were used to decorate hats and ladies' undergarments. The RSPB was set up to help protect this species, which is again a common sight.

Famous quotes containing the word behaviour:
“I look on it as no trifling effort of female strength to withstand the artful and ardent solicitations of a man that is thoroughly master of our hearts. Should we in the conflict come off victorious, it hardly pays us for the pain we suffer from the experiment ... and I still persist in it that such a behaviour in any man I love would rob me of that most pleasing thought, namely, the obligation I have to him for not making such a trial.”
—Sarah Fielding (1710–1768)
“The methodological advice to interpret in a way that optimizes agreement should not be conceived as resting on a charitable assumption about human intelligence that might turn out to be false. If we cannot find a way to interpret the utterances and other behaviour of a creature as revealing a set of beliefs largely consistent and true by our standards, we have no reason to count that creature as rational, as having beliefs, or as saying anything.”
—Donald Davidson (b. 1917)
“When we read of human beings behaving in certain ways, with the approval of the author, who gives his benediction to this behaviour by his attitude towards the result of the behaviour arranged by himself, we can be influenced towards behaving in the same way.”
—T.S. (Thomas Stearns)
