Migration Patterns - GCSE Biology Definition

Migration patterns are the regular, often seasonal, movements of groups of animals from one place to another and back again. These movements can cover long distances and are common in birds, fish and mammals. They are triggered by factors such as food availability, breeding sites or temperature changes. For example, many birds migrate to warmer countries in winter to find more food and then return in summer to breed. Understanding migration patterns helps scientists learn more about the habits and needs of different species, which is important for conservation efforts.
