Detailed explanation-1: -If a female greylag goose’s egg rolls out of her nest, she will instinctively use her bill to push the egg back into the nest in a series of very stereotyped, predictable, movements. The sight of an egg outside the nest is the stimulus that triggers the retrieval behavior.
Detailed explanation-2: -Greylag goose egg-retrieval behavior The sight of the displaced egg is the sign stimulus and elicits the egg-retrieval behavior. First, the goose fixates its sight on the egg. Next, it extends its neck over the egg. Finally, it rolls the egg back to the nest using the underside of its beak.
Detailed explanation-3: -Fixed action patterns are behavioural sequences that occur as a result of innate releasing mechanisms. For example, when a dog sees a cat running away from them, they have an instinctive response to chase the cat.
Detailed explanation-4: -For example, a newborn infant will reflexively grab on to any object that is tendered. Studies have also demonstrated that babies will instinctively grab on to a rope to avoid falling. In addition, newborns have been found to grasp hair more firmly than other objects.
