The greylag goose (Anser anser), the largest and bulkiest of the grey geese (length 75–90 cm; mean mass: males 3.5 kg, females 3.0 kg; Beaman & Madge 1998), is the type species of the genus Anser and also the ancestor of the domestic goose (A. a. domesticus) in Europe and North America.

The Greylag Goose (also spelled Graylag in the United States), Anser anser, is a bird with a wide range in the Old World.It is the type species of the genus Anser.. It was in pre-Linnean times known as the Wild Goose ("Anser ferus").This species is the ancestor of domesticated geese in Europe and North America.Flocks of feral birds derived from domesticated birds are widespread.

Anser anser, the greylag goose, is a member of the waterfowl family Anatidae.It was first described by the Swedish naturalist Carl Linnaeus in 1758 as Anas anser, but was transferred two years later to the new genus Anser, erected by the French zoologist Mathurin Jacques Brisson, where it is the type species.Two subspecies are recognised; A. a. anser, the western greylag goose Motor Output Fixed Action Pattern FAP Lorenz Example 1 Greylag goose egg from BIOLOGY 143 at University of Iowa Konrad Zacharias Lorenz (German pronunciation: [ˈkɔnʁaːt ˈloːʁɛnts] (); 7 November 1903 – 27 February 1989) was an Austrian zoologist, ethologist, and ornithologist.He shared the 1973 Nobel Prize in Physiology or Medicine with Nikolaas Tinbergen and Karl von Frisch.He is often regarded as one of the founders of modern ethology, the study of animal behavior.

Greylag goose egg-retrieval behavior

The egg-retrieval movement shows many characteristics typical of motor programs. The behavior is stereotyped or fixed in form. It is set off by a highly specific stimulus called a sign stimulus or releaser. Once triggered, the action runs to completion (endogenous running-out). Egg-retrieval behaviour. Another example of a behaviour that has been described as a FAP is the egg-retrieval behavior of the graylag goose, reported in classic studies by Niko Tinbergen and Konrad Lorenz. Like many ground-nesting birds, if an egg becomes displaced from the nest, the greylag rolls it back to the nest with its beak.
