With the increasing of the world temperature due to the emission of carbon dioxide, the habitats and movements of migratory birds are changing gradually. Take the three typical migratory birds in UK-- the tufted duck, goosander and goldeneye, as example. In the past, these birds live in Northern Europe in the summer and immigrate south to the UK in the winter. However, the climate change makes the migration of these birds less important or even unnecessary. Due to the higher temperature in Northern European, more birds prefer to find foods and stay in their summer habitant, rather than fly to UK to survive the winter. This phenomena is called “short-stopping”. It may seem to be a good thing for these birds since they are able to save the energy and avoid the possible accidents during the migration. But what the scientists are worried about is that there are no corresponding facilities to help birds survive winter in Northern Europe and this shift in migration may influence the ecosystems in both Northern Europe and UK. Basically, more international cooperation is needed to share the experience to protect migratory species with the change of the global climate.
