Taxonomy

The great crested grebe was formally described by the Swedish naturalist

Carl Linnaeus Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, ...

, with some larger species residing in the Americas. They measure long with a wingspan and weigh . 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. The young are distinctive because their heads are striped black and white. They lose these markings when they become adults.

Distribution

The great crested grebe breeds in vegetated areas of freshwater lakes. The subspecies ''P. c. cristatus'' is found across

Behaviour

Breeding

The great crested grebe has an elaborate mating display. Like all grebes, it nests on the water's edge. The nest is built by both sexes. The

averages four chalky white eggs which average in size and weigh . Incubation is by both parents and begins as soon as the first egg is laid. The eggs hatch asynchronously after 27 to 29 days. The precocial young are cared for and fed by both parents. Young grebes are capable of swimming and diving almost at hatching. The adults teach these skills to their young by carrying them on their back and diving, leaving the chicks to float on the surface; they then re-emerge a few feet away so that the chicks may swim back onto them.

Feeding

The great crested grebe feeds mainly on fish, but also small
