Harpy eagle – The most powerful eagle on earth
Eagle is majestic, powerful and elegant. At the moment the most powerful eagle alive is Harpy eagle… this eagle is very huge eagle with powerful talon and feet.
The body of harpy eagle measures about 1 meter with the weight of the considerably 7.5 –9 kilogram. The male however is a bit small with only weight 4 –4.8 kilogram.
I think harpy eagle can consider as king of the forest (bird) in their place as they hunt for large mammals like monkeys and sloth. They have very powerful talon which is about the size of grizzly bear claws. It is said that those powerful feet and talons can exert up to several hundred pounds (more than 50kg) of pressure. The sharp claw definitely will able to crush the bone of their prey which they snatches from the forest canopy, which normally their prey will die instantly due to the injury.
Previously harpy eagle range from southeast Mexico to Argentina. Now, Panama’s pristine rain forests are among the few places where the bird has survived. There are lots of decline, mostly because of the deforestation activity… poor bird, powerful but nearly extint because of other people fault..
Each pair of harpy eagle need about 20 square kilometre of healthy forest to thrive. Therefore if the forest is reducing, their chance of survive and breed successfully is reducing too. The female lay usually 2 eggs in a broad nest of wide sticks that are built 50-75 meter above the ground in the crown of the tallest trees. The baby will only test their wings (fly) at about 6 month old and their parent will still looking for and feed them for another year… since it has already take almost two year to raised a young, a pair of harpy eagle will only breed once in two to three year. The young will reach their sexual maturity at about 4 to 5 years old.

Most Powerful Eagle on Earth!
RECORD: Largest documented prey taken and carries by an eagle in the wild.
Here are some Eagle species records;

The Philippine Eagle largest documented prey is a 14 kg or 30.8 lb Philippine cervus deer at a nest studied by Kennedy in 1985;
(Excerpt from the book Threatened birds of Asia)
Food: general considerations The variety and size of prey items recorded (from 10 g bat to 14 kg deer) at a nest studied by Kennedy (1985; see below) suggest that Philippine Eagles are opportunistic feeders. This is supported by various general statements from earlier investigators: Wharton (1948) described them as feeding on almost all native mammals and some reptiles, often catching flying lemurs, while Grossman and Hamlet (1964), evidently based on J. Hamlet’s personal experience (see Kennedy 1977), reported that the eagle “feeds on monkeys… as well as hornbills, and also preys on small dogs, pigs and poultry in native villages” and that “pairs may specialize and bring up their young on an almost exclusive diet of any one of these items, depending on the location of the nest and whatever is most available and vulnerable”

Taking a mature female monkey in one foot in Luzon, Cagayan, I reckon it’s a green monkey or Philippine long tailed-macaques-the only native species in the
Philippines and weighs about 4-6 kg up to 9 kg for males.
Attacks a large python!…one of the most impressive for me!
“(an eagle was seen taking an adult female monkey in Cagayan, carrying it in one foot: R. Crombie in litt. 1998) and reptiles, and in addition giant
cloud-rats Phloeomys pallidus that weigh 2–2.5 kg (over twice the weight of flying lemurs) (L. R. Heaney in litt. 1997). Gonzales (1971) had a local report of a bird being captured alive after falling exhausted in combat with a large python.”
