Podiceps (Grebe) is a genus of birds of the family Colymbidae characterized by a straight conical bill, no tail, a short tarsus, flattened toes which are separate but broadly fringed at their edges by a firm membrane and legs set so far back that on land the Grebe adopts the upright stance of a penguin. They are excellent swimmers and feed on small fish, frogs, crustaceans and insects. Research Podiceps
