    • In Africa and on migration routes, climate change can have a serious impact. Research has shown that swallows are returning to their breeding areas in poor condition and laying fewer eggs than in the past.<\/li>
    • The adverse weather conditions in Europe are affecting swallows: Cold seasons with recent frosts are difficult for these small birds.<\/li><\/ul>Hot, dry summers mean that water troughs where insects are present dry out and nests can die from overheating.
      Constant rainfall over long periods of time makes it difficult for adult swallows to find food, and some die as a result.<\/span>\n\t\t\t\t\t\t\t\t\t<\/li>\n\t\t\t\t\t\t\t\t

      Nests are often attacked by rats, mice and snakes that eat the eggs and chicks while predators attack the young. Birds of prey such as hawks, owls and eagles can take all the young from a nest, leaving no trace.<\/span>\n\t\t\t\t\t\t\t\t\t<\/li>\n\t\t\t\t\t\t\t\t
