The egg retrieval response of the greylag goose. The chin-tucking movements used by the female as she rolls the egg back to the nest are highly stereotyped and are an example of a fixed action pattern. The side-to-side movements that correct for any deviations in the path of the egg are termed the taxis component of the response.

Egg Rolling and the Greylag Goose Niko Tinbergen, a pioneering researcher of animal behavior, studied the egg rolling behavior of the 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. Fig. 3—1 The egg-rolling response of the greylag goose- The behavior begins when the brooding goose notices an egg outside the nest (A) and fixates on it. 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.
