CHANGES IN MIGRATION OF BIRDS OF PREY OVER THE PAST DECADE
CHANGES IN MIGRATION OF BIRDS OF PREY IN (a geographical region) OVER THE PAST DECADE INTRODUCTION Birds are one of the best groups of animals for monitoring the effects of climate change. They are day-time active, conspicuous, easy to identify, and are popular with many groups of people, including amateur birdwatchers and professional scientists. In many parts of Europe, their distributions and numbers, as well as the timing of their migrations and breeding seasons, have been well monitored for decades. Migratory birds are likely to be more vulnerable than non-migrants because they can influenced by conditions in three different geographic locations : their breeding grounds, their winter areas, and their migration routes. Individual birds also experience “carry-over effects,” such as when conditions experienced in wintering areas influence subsequent breeding success, or when conditions experienced on the breeding grounds influence subsequent over-winter survival.
