Birds Migrate At The Right Time
September 3, 2010
The music of the singing birds on the trees and bushes in North America which were not heard the day before shows the arrival of spring. The birds are more perfect in time than the human. All these birds after spending their winter in various part of America reach north in the spring. The arrival of birds is done gender-wise. First, the Male birds arrive and watch for a best area, most probably finalizes the previous year location. Then, the female birds arrive and depending upon the habitat selects the male bird. Both the birds put up a nest and raise offspring before the time arrives to leave for winter.
