The great crested grebe (Podiceps cristatus) is the largest member of the grebe family. 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. It is an excellent swimmer and diver, and pursues its fish prey underwater. The adults are unmistakable in summer with ornate head plumes. It is found on reedy lakes, rivers, gravel pits and reservoirs. In winter visiting birds can also found in coastal areas. They have an elaborate courtship display in which they rise out of the water and shake their heads. Great Crested Grebes teach their young to swim by carrying them on their back and diving, leaving the chicks on the surface. Then they emerge a few feet away so that the chicks can swim back onto them. In the 19th century, this species was hunted almost to extinction in the United Kingdom. Its head plumes were used to decorate hats and ladies undergarments. They can be found in Europe and Asia including India.
