Advantages of migration behaviors-biology

1. Return to specialist site for breeding that does not need all year round food supply, and often no (or few) predators.
2. Move to where food/prey available when not breeding, particularly with young (i.e. maximize feeding opportunity).
3. Stationary can mean increased predator risk.
4. Constant temperature conditions: escape bad weather and lower temperatures (and greater risk of death), especially to give birth.
5. Able to have specialist breeding site (e.g. no predators) and another site for feeding.
6. Flexible strategy – some members of the species can migrate and others not depending on where live.
7. Stationary animals risk exhausting food supply using it all year round, particularly if competition from other species.
8. Opportunity for different members of the species to meet, and greater breeding variety
9. Ideal when specialist food required because the earth’s resources are not evenly distributed.
10. Birds migrating at night usually safe from predators as few day-time birds of prey adapt to night-time hunting.
