The skvader is a Swedish fictional creature that was constructed in 1918 by the taxidermist Rudolf Granberg and is permanently displayed at the museum at Norra Berget in Sundsvall. It has the forequarters and hindlegs of a European hare (Lepus europaeus), and the back, wings and tail of a female wood grouse (Tetrao urogallus). It was later jokingly given the Latin name Tetrao lepus pseudo-hybridus rarissimus L.
The name is a combination of two words, and this is the explanation provided by the Svenska Akademiens Ordbok (Dictionary of the Swedish Academy): "The prefix skva- from 'skvattra' (quack or chirp), and the suffix -der from 'tjäder' (wood grouse)".
The skvader originates from a tall tale hunting story told by a man named Håkan Dahlmark during a dinner at a restaurant in Sundsvall in the beginning of the 20th century. To the amusement of the other guests, Dahlmark claimed that he in 1874 had shot such an animal during a hunt north of Sundsvall. On his birthday in 1907, his housekeeper jokingly presented him with a painting of the animal, made by her nephew and shortly before his death in 1912, Dahlmark donated the painting to a local museum. During an exhibition in Örnsköldsvik in 1916 the manager of the museum became acquainted with the taxidermist Rudolf Granberg. He then mentioned the hunting story and the painting and asked Granberg if he could re-construct the animal. In 1918 Granberg had completed the skvader and it has since then been a very popular exhibition item at the museum, which also has the painting on display.
Similar creatures 
A strikingly similar creature called the "rabbit-bird" was described by Pliny the Elder in Natural History. This creature had the body of a bird with a rabbit's head and was said to have inhabited the Alps.
The skvader has since then often been seen as an unofficial symbol for Sundsvall and when the province Medelpad was to be given a provincial animal (in addition to the provincial flower) in 1987, many locals voted for the skvader. The final choice was a kind of compromise, the mountain hare, which is the front-end of the skvader.
Other uses 
"Skvader" also became the nickname in the 1950s and 1960s for a combination bus and lorry (truck) which was commonly used on small bus routes in Norrland; the front-end was a bus taking passengers and the back-end was an open loading bay, often used for delivering milk from small farmers to the nearest dairy.
