Climate Adaptations

Climate change is expected to significantly impact migratory birds through timing of events like migration or breeding. Responses may include arriving at their breeding grounds earlier as global temperatures rise. They may also start appearing in new areas as climatic events alter preferred habitat, natural resources and migration routes.
