The Endangered Species Act saved many species. For example, the American alligator, bald eagle, peregrine falcon, and brown pelican. These animals were close to extinction. Luckily, they are now recovering.
The bald eagle, with only 487 nesting pairs, made the endangered species list in 1967. Now, it is found the species is doing well with an estimated 4,215 pairs and ESA considers bald eagles are no longer in need of protection.
The gray whale was hunted nearly to extinction in the early 20th century, but a ban on commercial whaling and other conservation measures helped the population recover. Today, there are estimated to be around 27,000 gray whales in the wild.
The southern white rhino was once thought to be extinct in the late 19th century due to hunting and habitat loss, but a small population was discovered in South Africa and conservation efforts have led to their recovery. Today, they are classified as “near threatened” rather than endangered.
