Harpy or Buteonine Eagles
In the rainforests of South America, Mexico, New Guinea and the Philippines, this group of six includes some of Britain's most impressive in the world, the harpy eagle, the eagle in New Guinea and the Philippine eagle.
Although other eagles is almost as heavy and some are larger, the harpy eagle of South America is unquestionably the most powerful eagle in the world. A female Harpy Eagle can weigh nearly 20 pounds (9 kg). His legs may be as large as in the wrist of a child, her feet tipped with 1.5-inch long (3.75 cm long) claws can span 9 inches (22.5 cm). With legs and claws, the harpy able to capture large prey tree, including sloths and howler monkeys on the branches where they live. The images needed to idle in Guyana to reveal the technique used by the harpies to take a lazy hung from a branch. Skillfully roll in flight to pass under the branch, the eagle took laziness, snatched the loose, and she realized with almost a break in his harpy eagle swooping down flight.A to 20 miles per hour (32 km / h ) generates about 13,500 foot-pounds (18 300 Newton-meters) of energy - more than twice the muzzle energy of a projectile shot from a heavy gun.
