The African Goose is one of two domestic goose breeds that derive from the wild species Anser cygnoides, the other being the Chinese, to which it is closely related. [9]: 364 [3] Domestication took place in north Asia, and birds of this type were later brought to Europe, possibly via Madagascar; [10] they were present in Britain before the end of the seventeenth century.
Canada geese in Cincinnati parks have been responsible for knocking people down and breaking their bones, and called "spitting, hissing, biting attack missiles". [6] The same aggressive, territorial behavior can be utilized in the guard capacity. Geese are intelligent enough to discern unusual people or sounds from usual stimuli.
A greylag goose which participates in the described egg-retrieval behavior. Another example of a behavior that has been described as a fixed action pattern is the egg-retrieval behavior of the greylag goose, reported in classic studies by Niko Tinbergen and Konrad Lorenz. [5]
The Egyptian goose (Alopochen aegyptiaca) is an African member of the Anatidae family including ducks, geese, and swans. Because of their popularity chiefly as an ornamental bird , the species has also been introduced to Europe, the United States and elsewhere outside their natural range.
Behavioral ecology, also spelled behavioural ecology, is the study of the evolutionary basis for animal behavior due to ecological pressures. Behavioral ecology emerged from ethology after Niko Tinbergen outlined four questions to address when studying animal behaviors: What are the proximate causes, ontogeny, survival value, and phylogeny of a behavior?
For example, a young goose instinctively bonds with the first moving stimulus it perceives, whether it be its mother, or a person. Lorenz showed that this behavior of imprinting is what allows the goose to learn to recognize members of its own species, enabling them to be the object of subsequent behavior patterns such as mating.

Abnormal behavior of birds in captivity has been found to occur among both domesticated and wild birds. [1] Abnormal behavior can be defined in several ways. Statistically, 'abnormal' is when the occurrence, frequency or intensity of a behaviour varies statistically significantly , either more or less, from the normal value. [ 2 ]
The spur-winged goose (Plectropterus gambensis) is a large, Sub-Saharan African waterbird in the family Anatidae, which includes geese and shelducks.However, P. gambensis developed unique environmental adaptations, which resulted in the evolution of several anatomical features that are not shared with other anatids; thus, the species has been classified one step further into its own subfamily ...
