A bird of prey or a raptor is a bird that hunts and eats other animals. Because the prey is often large relative to the predator, these birds are equipped with sharp, hooked bills to tear into their food and large, sharp talons to grab and hold on to it tightly. Though people know that eagles and hawks are birds of prey, some are surprised to learn that vultures and condors are also birds of prey. It’s true that vultures and condors are mostly scavengers, but they will hunt for food, especially if the prey is sick or weak. Here is a list of the biggest birds of prey in ascending order:
#10 The Biggest Wingspan – Steller’s Sea Eagle
This huge eagle of the northeastern part of Asia has a bright yellow beak, yellow talons, dark brown feathers with white bands on its wings, white feathers over the thighs and legs, and a white tail. It is considered the heaviest eagle in the world and usually weighs in at about 11 to 20 pounds. Its talons are formidable, and the feet also possess spicules at the bottom which let the bird hold onto struggling fish. The fish the Steller’s sea eagle prefers are types of salmon, stickleback, trout, cod, and pollock. The eagle is powerful enough to take large birds such as geese, swans, and even albatross. The conservation status of Steller’s Sea Eagle is vulnerable.
#9 The Largest Sea Eagle – White-tailed Eagle
As the bald eagle is found in America, its close cousin the white-tailed eagle is found largely in Russia and Eurasia. It is a sea eagle that usually lives along bodies of water. It is brown and gray all over save its while tail and can range in length from 26 to 37 inches with a wingspan of between nearly 6 feet to 8 feet. Females usually weigh from around 9 to 15 pounds while males weigh about 7 to 12 pounds. The eagle can also be recognized by its calls, which sound like a series of yelps. It often scavenges but is an exceptionally agile flyer and has been seen to snatch fish and waterfowl from bodies of water.
#8 The Biggest National Bird – Bald Eagle
The national bird of the United States and found throughout much of North America, the bald eagle’s pure white head and neck and white tail and rump are very recognizable. It most often catches live prey, including seabirds such as ducks and seagulls and fish including salmon. Yet the bald eagle is not above scavenging and even stealing food from other animals, especially the smaller Osprey. It prefers to roost in tall trees, even though it is challenging for this big bird to fly through a dense canopy. It ranges between 30 and 43 inches long, weighs about 9.47 pounds, and has a wingspan between 6 and 7.5 feet. It takes five years for a bald eagle to achieve its unique plumage, and even then it may still have some of the dark feathers of its younger days.
#7 The Flying King of the Sky – Harpy Eagle
This enormous eagle is renowned for the size of its feet and the fearsomeness of its talons. It is a predator in the rainforests of Central and South America and can be seen flying through the dense trees effortlessly as it hunts possums, snakes, monkeys, and sloths. Though it’s not the longest eagle, it is one of the largest, with a wingspan of nearly 7 feet and an average length of between 35 and 43 inches. It weighs between 11 and 20 pounds. It’s a striking bird with a slate-colored back, barred, black, and gray tail feathers, light gray head and thighs, and a light-colored breast and belly. The eagle has a crown of feathers that it raises either because it’s threatened or to allow it to hear better or for both reasons. Harpy eagles mate for life and can live between 25 and 35 years in the wild.
#6 The Biggest Raptor in Asia – Philippine Eagle
As its name states, this eagle is found in the Philippines and lives in the rain forest. Because of this, it has a more slender silhouette than most eagles, but it is one of the biggest raptors at around 37 inches long. The bird weighs between 8.9 to 17.6 pounds. It’s brown on top with a white belly and throat, and its wings are large and have round tips. It also has a brown and white crest, yellow legs, powerful talons, and a large, curved beak. The bird’s beak and talons allow it to seize any prey it can handle, from monkeys to rats to birds to small deer. Though this eagle is revered and is the national bird of the Philippines, it’s still critically endangered due to habitat destruction.
#5 The Most Aggressive Birds of Prey – Lappet-faced Vulture
This vulture, also called the Nubian vulture is made up of two subspecies. One lives in much of Africa while the other is found in the Middle East. It prefers dry, open areas though it can also be seen now and then near human dwellings in search of road kill. It’s a cousin of the cinereous vulture and is just a little smaller at 37 to 45 inches long with an 8 to 9.5 foot wingspan. Like other vultures, this one has a bald head, but its skin is wrinkled and folded, which gives the bird its name. The vulture is not only big but aggressive and will often take over a carcass from smaller vultures. This benefits both vultures because the lappet-faced is strong enough to tear open the tough hide of animals such as an elephant or buffalo. In doing this, the lappet-faced vulture and other animals can partake of the meat.
#4 The Birds of Prey in the Mountains – Lammergeier
This bird of prey is also called the bearded vulture, but it’s more closely related to eagles and hawks. Indeed, its head is fully fathered, even though it does eat carrion. There are 13 subspecies and that are found throughout Africa, Spain, India, Tibet, parts of China, and Siberia. It resides in the mountains, which gives it a good view of prey animals, especially those that have been freshly killed by predators. These huge birds range in length from 37 to 49 inches and have a wingspan between 7.6 and 9.3 feet. Females are larger. Interestingly, lammergeiers sometimes form threesomes, with two males vying for the same female. They’re also different from other vultures in that they bring pieces of prey to their chicks as opposed to regurgitating them.
#3 The Heaviest Vulture – Cinereous Vulture
This vulture is one of the biggest of the Old World vultures. Also called the black vulture or monk vulture, this bird can be almost 4 feet long, weigh around 30 pounds, and have a wingspan that’s a little over 10 feet. It is not only one of the largest of the flying birds but one of the heaviest. It’s found from Spain down into the Middle East and east into China and Mongolia. Its body is covered with brown feathers, and it has bluish-gray skin. The bird’s head has a fine, dark color, and when it’s flying the bird can seem completely black to a person on the ground. This illusion gives it one of its names. These vultures, which nest on cliffs, are devoted parents, and their well-fed chicks can weigh more than their parents by the time they fledge.
#2 The Birds of Prey of West and South America – Andean Condor
Though the Andean Condor is about 2 inches shorter than the California condor, it is heavier and has an even longer wingspan. The Andean condor can weigh as much as 33 pounds and have a wingspan from 9 to a little over 10 feet. The female is smaller than the male, which is unusual for raptors. She also differs from him in that he has a comb and a wattle while she doesn’t. Males also have brown eyes while the eyes of the females are red. Like other vultures, they both have naked heads and necks, which makes it less messy to plunge their heads into the innards of rotting carcasses. They can also change the color of the skin of their head and neck according to their mood. This condor is found in the mountains and deserts of western South America.
#1 The Condor of the Dessert – California Condor
At between 46 and 55 inches from its head to its tail, the California condor is the largest bird of prey in the Americas. It can weigh as much as 23 pounds and have a nine-and-a-half-foot wingspan. Its head and neck are naked save for some black feathers on the forehead and the ring of black feathers around the neck. This bird of prey was once found up and down the west coast of North America but now is found only in the deserts of south-central California. California condors, who do mostly eat carrion, are fastidious about their persons and spend much time grooming and preening themselves. A California condor can live as long as 45 years in the wild.
