Compare and contrast how two different animals migrate?

Both fish and birds are similar because of their species. A bird is different from a fish because 1,800 of the world's 10,000 bird species migrate long distances each year in response to the seasons.[8] Many of these migrations are north-south, with species feeding and breeding in high northern latitudes in the summer, and moving some hundreds of kilometers south for the winter. A fish is different from a bird because Most fish species are relatively limited in their movements, remaining in a single geographical area and making short migrations for wintering, to spawn, or to feed. A few hundred species migrate long distances, in some cases of thousands of kilometers.So that is the compare and contrast of two animals now help me with mine
