Harpy Eagle Information

Harpy eagles live in the rainforests of Central and South America. Harpy eagles are the largest and most powerful birds of prey in the Americas. They are also known as American harpy eagles, and in Brazil as royal hawks. The harpy eagle’s scientific name is Harpia harpya.

The harpy eagle is the national bird of Panama.

Harpy eagles have the largest talons of any eagle, and think nothing of plucking monkeys or sloths out of trees. Harpy eagles are the apex predators (i.e. they’re top of the food chain) in their rainforest ecosystems.

What Does A Harpy Eagle Look Like?

Harpy Eagle

Harpy eagles’ plumage is a mixture of dark greys and white.

The back and upper wings of a harpy eagle are dark grey. Its undersides and legs are white, and there is a wide grey ‘collar’ around its neck. Its legs are white with distinctive black stripes.

The bird’s head is white / grey, and it has a feathered crest which is raised when the bird is threatened or excited.

It is thought that the feathers around the harpy eagle’s face direct sound towards its ears.

Harpy Eagle Size

Harpy eagles are well known for their large size, and are the heaviest raptors in the americas.

Like many birds of prey, the female harpy eagle is larger than the male. One reason for this may be so that the male and female are not competing for the same prey. Female harpy eagles tend to hunt larger creatures than the males.


The wingspan of a harpy eagle can be over 2 metres (6.5 ft) wide. Their wings provide the lift that allows them to carry prey items weighing more than 7kg. Their bodies can be up to 1 metre (3 – 3.5 ft.) long.

Harpy eagles are built more for a quick chase than a sustained pursuit, and can reach speeds of 50 mph (80 kmph)!

Andean Condor Flying

The harpy eagle is the heaviest bird of prey in the Americas, but the Andean condor, above, has the longest wingspan.


Full-grown female harpy eagles weigh between 6 and 9 kilograms. The males are smaller and lighter, tipping the scales at around 4 to 6 kilograms.

Are Harpy Eagles Endangered?

Harpy eagles are classified as ‘near threatened’ on the IUCN Red List. The harpy eagle’s territory has vastly diminished over the years as a result of deforestation. Despite being protected in several areas, they are also occasionally hunted.

Harpy Eagle Hunting Methods

Harpy eagles are diurnal, which means that they are active during the day. A harpy eagle’s favoured method of hunting is ‘perch hunting’. It flies from tree to tree in search of prey. When suitable prey is spotted, the bird swoops down and grabs it in their talons.

Another hunting tactic used by a harpy eagle is ‘sit and wait’ hunting, in which the bird perches in the same place until the prey wanders into view. Harpy eagles have been known to wait up to 23 hours for prey to appear using this method.

Harpy eagles will also hunt other birds by pursuing them through the trees.

Harpy Eagle Diet

    I would like to set the record straight on these majestic eagles .
    This is fact in 1972 I seen one of these eagles in my Grandmas yard. It was flying west from the achafalaya basin in louisiana I was in the town of arnaudville where my family the B roussards have lived for over 150 years . Yes I had my cousin a witness with me.
    I would like to point out this eagle I seen wings were longer than the cattle gate that was 12 feet . When he flew over it his wings stretched past the ends of the gate . I thought it to be a extinct bird from the dinosaur age.
    I did take a shot at it with my pellet gun a 22 caliber Benjamin pump rifle pumped 10 times . Only because when he turned to look at me he was looking at me like food im 1/2 cajun 1/2 cherokee. I was an avid hunter and thanks to my grand mother I was charged with sitting under her fig trees when the figs began to ripen.
    The worst bird was the mocking bird they would just peck holes in the figs to draw in bugs to eat.
    but back to the eagle . When I shot he just shook his head and gave me a look like yummy some food. My cousin said lets run and grab its legs and we can catch it! I said are you insane look at the size of his leg and claws and that beak is ten times bigger than my moms largest parrot and they will bit the end your finger right off.. I said and I just shot and it didnt even bother it . But it looked at me like I was food ain’t no way im grabbing that thing. Well he took a running distance of 20 feet flapped his wings barely cleared the gate and when he flew right over the trees the chicken trees tops waved like a wind from a hurricane was blowing in.
    I have never been able to tell my story cause no one would believe me. Ya know they all said it was like the fish story I caught a fish this big ya know.
    Well thats my story of how at 13 years of age in the summer of 1972 I seen the. First of these birds until the PBS special a few. Years ago. . I finally could tell all my. Family that thst was the bird I had seen .
    well I hope they are protected well. Also when it blinked its eyes they changed colors when closed then back to other color I t was blue when he plinked about scared the pants off me.
    I was lucky I seen this eagle that had been living in Louisiana swamps. And bayous. I believe It to be the last one left in Louisiana. I hope this post will help shed some light on the true size. Of these beautiful but dangerous birds. At least when thier hungry and you happen to be a 12 year old. Lol
