Why do ducks migrate?
There are some places like New York where small lakes, ponds and lagoons exist with the formation of heavy snow in them. The ducks will not be able to survive in these lakes when there is snow formation. Ducks were observed to be migrating like that of birds to the warmer places where they can keep their bodies warmer. But there is no pattern for their migration and will not move from one place if the weather is good.
Duck migration is the traveling of some duck and bird species every year from their original and permanent homes in the North of United States towards the south during the winter for surviving better. There are some reasons for the ducks to move every year to a new place. The reasons include feeding, breeding and avoiding cold winter. It is found that all the duck species will not migrate every year. Nearly 380 species of birds and ducks will carry out the migration every year towards the South from North.
Some of the ducks will be able to live in the North even in the coldest months while few cannot live. During the fall season the day light will be decreased and the day will become short. Hence, the place also starts becoming cooler slowly. This makes the ducks and birds to start migration. The American species of birds and ducks will move towards South during the fall to the Southern states, Central America, Caribbean and Mexico.
During the spring when the days are longer and the climate is hot in the North, the ducks will find the environment congenial for breeding in the North and hence they migrate towards North. It is probably the biological clock that is internal to their body which tells them to change their place in seasons and make them to move from one place to the other. They move many hundreds of miles towards South during the winter. It is more surprising that ducks move all through the distance on water for 50 hours without taking any break.
