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.

Lemmings migrate in large groups in search of new habitats.
It is an example of environmental polutants.
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)
There are many examples of environmental design processes. For example, using recycled paper for paper cases is an example of an environmental design process.
