Why do migratory birds fly to far away areas every year?
Habitats for feeding, breeding and raising their young.
Migratory birds fly hundreds and thousands of kilometers to find the best ecological conditions and habitats for feeding, breeding and raising their young ones. When conditions at breeding sites become unfavorable, it is time to fly to regions where conditions are better. Many birds' species all over the world are highly sensitive to the effects of climate change. Climate factors vary for different species of birds; for example, at high latitude, temperature is the greatest climatic influence for many species.
At low-latitude regions, which generally have consistently warmer temperatures, variables related to the surrounding bodies of water seem to have the most influence. For birds, a change in temperature can be one of the most threatening climate factors.
