Behaviour
These birds feed by swimming under water or diving. They also dabble. They eat molluscs, crustaceans and insects. Harlequins have smooth, densely packed feathers that trap a lot of air within them. This is vital for insulating such small bodies against the chilly waters they ply. It also makes them exceptionally buoyant, making them bounce like corks after dives.

Famous quotes containing the word behaviour:
“The quality of moral behaviour varies in inverse ratio to the number of human beings involved.”
—Aldous Huxley (1894–1963)
“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)
“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)
