Also seen are the coot, moorhen and little grebe (or dabchick). There is also a growing population of black swans and a few great crested grebe. The great crested grebe has an elaborate mating display. The type species was subsequently designated as the great crested grebe ("Podiceps cristatus"). The place is a known breeding ground of the Great Crested Grebe. Harrisson was instrumental in the organization of pioneering surveys of the great crested grebe. The black-necked grebe is socially monogamous. The black-necked grebe uses multiple foraging techniques. The little grebe is a small water bird with a pointed bill. This bird is closely related to the silvery grebe and the Junin grebe. Podiceps is a genus of birds in the grebe family. This grebe does not have webbed feet. Tachybaptus is a genus of small members of the grebe family birds. This grebe nests both in colonies and by itself.
