While seeing an animal in the wild can be fun, seeing thousands of them migrating is mesmerizing and awe-inspiring. These awesome wildlife photos will show you just how amazing of a sight a migration can be!Every year, birds, mammals, fish, reptiles and other animals around the world migrate for various reasons.
How they know when and where to go? Although seasons and temperatures seem to be the most important factor, the whole mechanism is not yet clearly understood. Migration yields things not usually seen - tree branches bending from the weight of butterflies, birds, flying from Alaska to New Zealand without stopping.Also animals don't always just travel across the map, either - some fish migrate to different depths!
