Common Pochard + Great Crested Grebe

The adult male has a long dark bill with a grey band, a red head and neck, a black breast, red eyes and a grey back. The adult female has a brown head and body and a narrower grey bill band. The triangular head shape is distinctive. Pochards are superficially similar to the closely related North American Redhead and Canvasback.------------The Great Crested Grebe (Podiceps cristatus) is a member of the grebe family of water birds.
The Great Crested Grebe is 46–51 centimetres (18–20 in) long with a 59–73 centimetres (23–29 in) wingspan. It is an excellent swimmer and diver, and pursues its fish prey underwater.
