Watch beautiful bird migration



Bird migration is nothing but the normal seasonal voyage undertaken by birds. This will be a fantastic sight for the bird watcher lovers. The bird migration can even happen in our backyards

The climatic changes in the length of the days make some hormonal changes in the birds which tends them to migrate

Birds usually migrate to long distance and the most common one is the migration of birds to north in spring and returning to their home place during winter. Migration can also take place due to some other reasons like food availability, weather, habitat, etc

During migration birds can fly to a height of about 500 to 2000 m. Some birds fly to a height of 6, 800 m and the swans fly to a height of about 8,000m. And the Bar-Headed Geese is found to fly at a height of about 9,000m
