Migratory patterns refer to the recurring routes taken by a species or a specific group of individuals within that species as they move from colder habitats to warmer ones during half of the year. For instance, Canadian Geese embark on migrations from the extremely cold winters of Canada to the relatively milder winters of lower America. Once the winter season concludes, they return to Canada to avoid the high temperatures experienced in lower America.

On the other hand, domesticated birds are those that have been tamed. This process involves gradually acclimatizing them to human presence and reducing their fear or discomfort around humans. Any pet bird can be considered domesticated, and there is a debate as to whether city birds such as pigeons and geese, which have adapted to urban environments and consume human-generated waste, can also be considered domesticated due to their familiarity with humans.
