A small South American grebe, the White-tufted Grebe is the only grebe with a tuft of white feathers on its otherwise entirely black head. It breeds on mostly on small inland bodies of water such as marshy ponds, temporary pools, roadside ditches and slow floating rivers. Unlike many other grebes, the White-tufted Grebe feeds generally from the surface of the water and dives less often. During the nonbreeding season, large groups of White-tufted Grebes in the southern portion of their range will congregate and migrate up the South American coast, forming flocks in bays and other sheltered coastal waters. Generally common throughout its range, the White-tufted Grebe is the most frequently observed grebe in Argentina.
