Author 'Fanfan' (Id 117292 ) : The great crested grebe is par excellence a waterbird. He spent his whole life to swimming and diving. Even the reproduction is performed on a floating nest near the shore. All the anatomy of this bird, the size of a mallard duck, is perfectly suited to this lifestyle: the streamlined body, long slender neck, the tail is very short and, most remarkable, the legs located well back as the propellers at the stern of a ship. Indeed it is only the legs, the fingers are provided with membranes, which provide propulsion and water. My first encounter with this beautiful bird.
