The factors behind the decline in the number
During the second half of the twentieth century, there has been an alarming rate of decline in the number of these birds. Factors which contributed to its decline has been the lack of suitable habitat, illegal shooting and use of DDT pesticides. Ingestion of DDT decreased calcium metabolism in the body, which affects the degree of sterility. Therefore, they were unable to produce healthy eggs. Because of these factors, these birds are included in the list of endangered species in 1967 by the U.S. government. But in 1972 the United States banned the use of DDT. This led to the revival of the population in the United States and Canada. In 1995 the U.S. U.S. Fish and Wildlife Service has decided to withdraw his name from the list of endangered species.
The Eagles are magnificent birds of America. Since the use of DDT was banned, the population of these birds has stabilized. So do your part for the environment by not using harmful pesticides.
