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.
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 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.
The African pygmy goose was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in his Histoire Naturelle des Oiseaux in 1785. [4] The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text.

Performing the egg tossing behavior increases the number of offspring per individual compared to those in single pairs. Many species have learned to adapt to this behavior to increase the chances of offspring survival. [10] The smooth-billed anis is one species that participates in communal breeding, where there are multiple females in a group. [3]
A salmon-crested cockatoo, showing signs of feather-plucking on its chest. Feather-plucking, sometimes termed feather-picking, feather damaging behaviour or pterotillomania, [1] is a maladaptive, behavioural disorder commonly seen in captive birds that chew, bite or pluck their own feathers with their beak, resulting in damage to the feathers and occasionally the skin.
The greylag goose was one of the first animals to be domesticated; this happened at least 3,000 years ago in Ancient Egypt, the domestic subspecies being known as A. a. domesticus. [7] As the domestic goose is a subspecies of the greylag goose they are able to interbreed, with the offspring sharing characteristics of both wild and domestic ...
