Slavonian, or horned, grebe (Podiceps auritus)

grebe, (order Podicipediformes), any member of an order of foot-propelled diving birds containing a single family, Podicipedidae, with about 20 species. They are best known for the striking courtship displays of some species and for the silky plumage of the underparts, which formerly was much used in millinery. The speed with which grebes can submerge has earned them such names as water-witch and helldiver, while the position of the feet near the tail is responsible for the early English name arsefoot, from which the family name was derived.

Adult grebes range in weight from less than 150 grams (5 ounces) to more than 1.4 kg (3 pounds) and in total length from 21 to 73 cm (8 to 29 inches). They vary principally in bill shape and ornamentation of the head. The group is found on all of the continents and on many island groups as well; however, it is best represented in temperate regions. Seven species each are found in North and South America, five in Eurasia, and three each in Africa and Australia. The species range from conspicuous and gregarious to solitary and skulking.
