The population could be reduced where the migrants are moving from.
Yes, geese migrating south for the winter is an example of innate behavior. It is an instinctual response that does not require prior learning and is genetically programmed in geese to ensure their survival and well-being during the colder months.
A population size decrease is the usual response in the population size of many species to a density-independent limiting factor. Not enough food is an example of a limiting factor.

The darkening of the population of the peppered moth in Europe over a relatively short time demonstrated natural selection in action. The change in moth coloration was a response to industrial pollution, where darker moths had a survival advantage in a polluted environment as they were better camouflaged from predators. This phenomenon provided a clear example of adaptation and evolution in response to changing environmental conditions.

Environmental backlash refers to negative reactions or repercussions that can occur in response to environmental protection efforts or policies. This can include opposition from industries, communities, or individuals who feel that environmental regulations are restrictive or harmful to their interests.
One example of a migrating rodent is the lemming. Lemmings are small rodents that live in the Arctic regions and are known for their cyclic population fluctuations and long-distance migrations in search of food and suitable habitats. During these migrations, lemmings may travel long distances, sometimes facing obstacles such as rivers or other natural barriers.
A reflex is an example of an involuntary response controlled by the spinal cord. It involves a rapid, automatic response to a stimulus without conscious thought.
A behavioral response to environmental variability or stimuli for example, is the change of seasons, global warming or an ice age. In the change of an animal's environment, such as season change; many migratory birds "fly south for the winter." And the Monarch Butterfly fly from Northern U.S.A. to South America. So the answer would be, "migrating to a different environment" Even during a global cooling or warming, this influences animals to migrate or die. Plants can't migrate and have to depend on the digestion of a bird or animal to redeposit its seeds elsewhere.
Adaptive Thermogenesis: This can be defined as the regulated production of heat in response to environmental changes in temperature and diet, resulting in metabolic inefficiency. For example, shivering when we are cold uses energy and this is an example of adaptive thermogenesis. (Alexander Bowring 24 / 04 / 2008)
