Podiceps cristatus

The great crested grebe (Podiceps cristatus) is a member of the grebe family of water birds noted for its elaborate mating display. Its scientific name comes from Latin: the genus name Podiceps is from podicis, 'vent' and pes, 'foot', and is a reference to the placement of a grebe's legs towards the rear of its body; the species name, cristatus, means 'crested'. The great crested grebe is the largest member of the grebe family found in the Old World, with some larger species residing in the Americas. They measure 46–51 cm (18–20 in) long with a 59–73 cm (23–29 in) wingspan and weigh 0.9 to 1.5 kg (2.0 to 3.3 lb). It is an excellent swimmer and diver, and pursues its fish prey underwater. The adults are unmistakable in summer with head and neck decorations. In winter, this is whiter than most grebes, with white above the eye, and a pink bill.
