With so many endangered and threatened species it’s hard to believe our planet is still inhabited by animals and what’s better is that the bald eagles are increasing in numbers.
The alarming numbers of endangered species are concerning many people, especially ecologists and nature lovers who know that soon enough many animals will go extinct. But there is one piece of happy news for them as the once endangered bald eagle species has been constantly increasing its population.
Bald eagles have been removed from the endangered species list in 2007 and from then on, their numbers have been increasing reaching a number of 161 nesting pairs in 2015. The report was given by the Conserve Wildlife Foundation in New Jersey.
The numbers are relatively high considering that in the 1980s there was only one nesting pair of bald eagles. In 2000, the number increased to 23; in 2005 there were 2005 and in 2010 there were 82. Therefore, their numbers pretty much doubled every five years since 2000, which is very encouraging.
And of course, the nesting pairs are not idle. 150 nests had eggs with a productivity rate of 1.33 offsprings which means that another 199 were born in the past year. It is likely that not all of them survived however, that is still a great number of bald eagles and it shows that their population will continue to rise.
The reduction of the bald eagles population happen in the early 1970s when a pesticide called dichloro-diphenyl-trichloroethane was used. In 1972, authorities banned the use of this pesticide, a fact which lead to the regaining of the bald eagle population in time.
The bald eagle, scientifically called Halliaetus leucocephalus, is a national symbol. To be more precise, it is considered America’s national animal. This eagle is a prey bird that usually hunts for fish.
An adult eagle has about 102 centimeters in lengths and a wingspan of approximately 2.3 meters. They can reach up to 4.1 kilos in weight. Therefore, we can say this is a pretty large bird. Moreover, given their highly sensitive senses and predatory skills, there’s no wonder the bald eagle is so popular among the American population.
