The goose rises, extending its neck to touch the egg (B). The goose places its bill carefully over the egg (C) and gently rolls it back into the nest (D). The egg (being egg shaped) tends to roll off to one side or another. "The goose moves her beak from side to side, keeping the errant egg on course. If it eludes her, she returns to the nest, spots the egg still lying outside the nest, and repeats the whole movement." (Bermant and Alcock, 1973) This video is helpful in understanding the fixed action pattern in animals Niko Tinbergen, a pioneering researcher in the area of animal behavior, studied the egg rolling behavior of a Greylag Goose as an example of an FAP. If one of the gooses’ egg rolls away from the nest, the goose automatically rolls the egg back to the nest with a repeated, specific action. A paradigm example of a fixed action pattern is egg-rolling behaviour in the greylag goose (Lorenz 1970: 316-350).

When a mother goose is incubating and somehow realizes an egg near the nest, its attention is stirred and then tries to roll the egg back to the nest. The ancestor of most domestic geese, the greylag is the largest and bulkiest of the wild geese native to the UK and Europe. In many parts of the UK it has been re-established by releasing birds in suitable areas, but the resulting flocks (often mixed with Canada geese) found around gravel pits, lakes and reservoirs all year round in southern Britain tend to be semi-tame and uninspiring.
