## Pied-Billed Grebe

### Podilymbus podiceps

The Pied-billed Grebe (Podilymbus podiceps) is a species of the grebe family of water birds. Since the Atitlán Grebe, Podilymbus gigas, has become extinct, it is the sole extant member of the genus Podilymbus.
The Pied-billed Grebe is small, stocky, and short-necked. It is 31-38 centimeters (12-15 in) in length, it has a wingspan of 45-62 cm (18-24 in) and weighs 253-568 grams (8.9-20.0 oz). It is usually brown or gray in color. It has a short, blunt chicken-like bill, which in summer is encircled by a broad black band (hence the name). It is the only grebe that does not show a white wing patch in flight. The sexes are monomorphic (meaning no sexual dimorphism).
Pied-billed Grebes feed mainly on aquatic invertebrates, and also on small fish and amphibians (frogs, tadpoles). Pied-billed Grebes have been shown to eat their own feathers to aid in digestion (prevent injury from small bones).
