Podiceps cristatus

The great crested grebe (Podiceps cristatus) is a member of the grebe family of water birds. The bird is characterised by its distinctive appearance, featuring striking black and white plumage, and elaborate courtship display that involves synchronised dances and displays.

Taxonomy

The great crested grebe was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Colymbus cristatus.^[2] It is now the type species of the genus Podiceps that was erected by the English naturalist John Latham in 1787.^[3]^[4]^[5] The type locality is Sweden.^[6] The 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 specific name, cristatus, means "crested".^[7]

Three subspecies are recognised:^[4]

P. c. cristatus (Linnaeus, 1758) – Eurasia
P. c. infuscatus Salvadori, 1884 – Africa
P. c. australis Gould, 1844 – Australia, Tasmania, South Island of New Zealand; known commonly as the Australasian crested grebe and, in the Māori language, pūteketeke

Description

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).^[8]^[9] 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 call is a loud barking rah-rah-rah. They can also produce a clicking kek call, and deep growls.^[10]

Juveniles are recognisable by their plumage, with their heads featuring alternating black and white stripes. 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 Europe and east across the Palearctic. It is resident in the milder west of its range, but migrates from the colder regions. It winters on freshwater lakes and reservoirs or the coast. The African subspecies P. c. infuscatus and the Australasian subspecies P. c. australis are mainly sedentary.

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 clutch averages four chalky-white eggs which average 54 mm × 37 mm (2.1 in × 1.5 in) in size and 42 g (1.5 oz) in weight. 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.^[11]

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 crustaceans, insects, small frogs and newts.^[12]

Relationship to humans

This species was hunted almost to extinction in the United Kingdom in the 19th century for its head plumes, which were used to decorate ladies' hats and garments. The Royal Society for the Protection of Birds was set up to help protect this species, which is again a common sight.^[13]

The great crested grebe and its behaviour was the subject of one of the landmark publications in avian ethology: Julian Huxley's 1914 paper on "The Courtship‐habits of the Great Crested Grebe (Podiceps cristatus)".^[14]^[15]

Conservation efforts have been taking place on New Zealand's Lake Wānaka since 2013.^[16]^[17]

The bird gained international attention on 5 November 2023, after comedian John Oliver highlighted New Zealand's Bird of the Year campaign in a Last Week Tonight episode and declared himself the "campaign manager" for the bird, which is also known in New Zealand by its Māori name pūteketeke.^[18]^[19] The bird was announced as the winner of the competition with the alliteration "Pūteketeke pandemonium prevails".^[20]
