What types of eagles can you find in Bosnia and Herzegovina?
Whenever they appear, I make sure to stop and watch these incredible birds of prey. I’m always amazed at their beauty, large size, and astonishing ability to soar at extreme heights! And I’m not alone, as eagles have a special place in many people’s hearts and minds.
Below are the eagles that live in Bosnia and Herzegovina!
Make sure to pay attention to the range maps to see which eagles live near you! In addition, I’ve included a few photographs to help you identify any birds you are lucky enough to observe for each species.
#1. Golden Eagle
- Aquila chrysaetos
- Adults have a length of 66 to 100 centimeters and a wingspan of 1.8 to 2.3 meters.
- The coloring is dark brown on the body, with a golden-brown head and yellow feet.
- The head seems small for the body and includes a hooked beak.
Golden Eagles are incredibly fast and agile, which makes them expert hunters. Where other eagles primarily eat fish or reptiles, these eagles almost always eat mammals. Their favorite prey includes rabbits, hares, ground squirrels, and marmots. But these raptors have been known to hunt and kill animals as large as small deer, badgers, or a bear cub. Talk about bravery (or stupidity?)! 🙂
Golden Eagles typically mate for life. To impress a female, male birds pick up a stick or a rock and fly up high, only to drop it. Then the eagle dives to catch the object again before it hits the ground! Once paired up, it’s common for them to hunt cooperatively, where one individual ambushes the prey and drives it towards the second bird to make the kill.
Golden Eagles are common to see in Bosnia and Herzegovina.
These birds prefer vast open areas that include cliffs, mountains, or hills. However, you can also spot these birds in grasslands, farmlands, shrublands, arctic tundra, and coniferous woodlands.
These eagles are not extremely noisy, and their calls sound like weak, high whistles. For such a powerful raptor, you’d think Golden Eagles would have a much more intimidating sound!
#2. Short-Toed Eagle
- Circaetus gallicus
- Adults typically range from 59 to 70 centimeters long with a wingspan of 162 to 195 centimeters.
- Their coloring is brown with a predominantly white underside.
- Black bars line the underside of their wings and belly and are visible when flying.
Short-Toed Eagles fly more than any other eagle in Bosnia and Herzegovina! They soar over their territory from a height of up to 500 meters, hunting from the air and diving to catch their prey.
Sometimes called Short-Toed Snake Eagles, this species primarily eats reptiles and occasionally birds and mammals. If they attempt to snatch a snake too large to pick up, they’ll fight it on the ground, grabbing at it with its claws and beak until the snake dies.
This species primarily lives in open plains and semi-desert regions where snakes are plentiful. Short-Toed Eagles in Bosnia and Herzegovina migrate to avoid cold winters, while those in Asia and the Middle East are year-round residents.
The species has a wide range and a large population, but it isn’t immune to threats from humans. For example, in 1993, 50 Short-Toed Eagles stopped in Malta during their migration, and they were all illegally shot and killed in one day.
You might have heard the call of a Short-Toed Eagle and assumed it was another water bird since they sound similar to gulls!
#3. Lesser Spotted Eagle
- Clanga pomarina
- Adults are typically up to 60 centimeters long with a wingspan of 150 centimeters.
- Their small, light brown head contrasts with their dark brown wings and body.
- Typically they have a white patch on the wings and a V-shaped marking near the base of the tail.
Lesser Spotted Eagles live in open country and lightly wooded grasslands. They are diurnal, meaning they sleep at night and hunt during the day. They primarily live in trees and hunt from perches, gliding down to capture small mammals for meals.
It’s rare for Lesser Spotted Eagles to hunt while flying, but they’ll walk on the forest floor to forage for food. They have keen eyesight and often hunt with other Lesser Spotted Eagles.
This species is one of the most territorial eagles in Bosnia and Herzegovina and will regularly fight other birds that encroach on its home range. Male Lesser Spotted Eagles are more aggressive than females and usually display aggression toward other males, while females protect nesting and roosting sites. Here, you can see a female doing just that on a nest camera.
Lesser Spotted Eagles are the only species in Bosnia and Herzegovina with the unusual habit of nest visitation.
The reason isn’t known, but females will often visit the nests of other females and stay for short periods before returning to their own territory. Researchers have discovered that females make these visits even if they aren’t closely related, almost as if they’re visiting for a neighborly chat!
#4. Booted Eagle
- Hieraaetus pennatus
- Adults typically are up to 40 centimeters long with a wingspan of 110 to 132 centimeters.
- Two distinct color morphs:
- The light morph is pale gray with a dark gray head and wings.
- The dark morph is mid-brown with dark gray wings.
- This species is relatively small and has a very short neck.
Booted Eagles in Bosnia and Herzegovina are migratory, living during the breeding season in open forests and hilly terrain. Then, they travel south toward Sub-Saharan Africa during winter. They will nest in nearly any protected area except for dense forests, which don’t allow them to fly freely.
The less-common dark morph of this species is often confused with the Black Kite due to their similar coloring and size. One way to tell the two apart is to look at the tail feathers. In Black Kites, the tail feathers are spread straight across and end in a sharp line. Booted Eagles have a fan-like tail with a curved edge.
Booted Eagles hunt from the air, circling above clearings and diving to catch smaller birds on the ground. They occasionally eat reptiles and mammals. Breeding pairs mate for life and can often be seen flying and hunting together. The best time to observe Booted Eagles in Bosnia and Herzegovina is March and September when they migrate. The birds are often secluded during the breeding season in forested nesting areas, and males only leave to hunt.
Even though the Booted Eagle’s habitat is threatened due to development and agricultural activity, its population is steady and not in decline.
Like other eagle species, Booted Eagles’ voices don’t really match their fierce looks! The short, high chirping notes sound more like a garden songbird.
#5. White-Tailed Eagle
- Haliaeetus albicilla
- Adults typically range from 66 to 94 centimeters long with a wingspan of 1.78 to 2.45 meters.
- Their coloring is grayish-brown with a lighter, striped head. They have black and yellow beaks and yellow feet.
- The tail feathers are white above and below.
White-Tailed Eagles are the largest eagle in Bosnia and Herzegovina!
They are one of the largest living birds of prey, growing to nearly a meter in length and a wingspan of almost 2.5 meters!
This species is associated with water and primarily lives in coastal regions of Bosnia and Herzegovina. Their habitats include estuaries, coastal marshes, and rocky beaches. If these habitats aren’t available, White-Tailed Eagles will nest and live in forested areas with nearby water.
You shouldn’t have any trouble recognizing this species since they’re the only eagle in Bosnia and Herzegovina with a completely white tail! They are also so large that they’re impossible to miss, whether flying or perching in a tree or at the edge of a cliff.
White-Tailed Eagles are patient, calm birds and can remain still, only occasionally calling, for hours at a time! They spend up to 90% of their day perched in trees or on cliff edges, occasionally taking flight and soaring over bodies of water.
Their primary diet is fish and water birds, but they’ll occasionally eat mammals if they’re more readily available. To catch fish, they perch until they spot their target near the surface of the water, then soar down and take it alive. Hunting water birds is trickier since most species are faster than the White-Tailed Eagle. As a result, they often use the element of surprise or wait until a bird is exhausted from hunting to catch and eat it.
#6. Imperial Eagle
- Aquila heliaca
- Adults typically range from 68 to 90 centimeters long with a wingspan of 1.76 to 2.2 meters.
- Their coloring is dark brown to black, with a light tan head and neck and bright white spots on the back.
- When in flight, the underside appears grayish with small white markings.
Imperial Eagles live primarily in taiga forests but range into grasslands and other open areas as well. You may even find one in an agricultural field, foraging for a meal. Look for them soaring over open areas searching for prey or perched in trees, taking a rest.
This species almost always hunts from above and takes its prey on the ground, soaring down to intercept it from its perch or the sky. Typically, the Imperial Eagle prefers small and medium-sized mammals, and also eats birds, frogs, and fish. Sometimes larger animals like foxes or domestic cats can fall victim to Imperial Eagles, but this is rare.
Like many other eagles in Bosnia and Herzegovina, Imperial Eagles mate for life and are often found as mating pairs in the wild. These mating pairs face the challenges of low breeding success and low survival rates to adulthood, which are rare problems for large raptors. Unfortunately, mating pairs of Imperial Eagles only have about a 50% success rate of raising their young to fledglings, and only 84% of fledglings reach adulthood.
These factors combined with nesting habitat loss, unintentional poisoning from wolf baits, and intentional killings have caused a widespread population decline of Imperial Eagles. Conservation efforts have been in place for the last 40 years across Bosnia and Herzegovina, which has helped this species regain some of its population. Habitat protection programs, the installation of artificial nesting platforms, and regulations on the use of traps and baits have all contributed to an increase in Imperial Eagles in Bosnia and Herzegovina.
#7. Bonelli’s Eagle
- Aquila fasciata
- Adults typically range from 55 to 74 centimeters long with a wingspan of 143 to 180 centimeters.
- The back and wings are dark brown, with a mottled white chest and a light brown head.
- The legs are unusually long, and the feet and talons are enormous for their size.
Bonelli’s Eagles live near large bodies of water like the Mediterranean Sea. They are permanent residents of their range and don’t typically migrate. Look for them in foothills and mountain areas with plenty of rocky cliffs to perch on.
Researchers have found that Bonelli’s Eagles also hunt in tandem with their mating partner. However, this doesn’t seem to help their success or increase the size of their meal. It’s more likely that this tandem hunting is done to strengthen the pair’s relationship. That’s a pretty unique date activity!
Bonelli’s Eagles hunt a wide selection of prey, including mammals, lizards, and smaller birds. They specialize in hunting European rabbits and partridges, and they will almost always seek them out to eat when available.
After they leave the nest for the final time, Bonelli’s Eagles disperse to find their own territory and begin the process of finding a mate. They have the widest dispersal area of any eagle in Bosnia and Herzegovina, traveling up to 536 kilometers away from their nest. This is thought to contribute to a healthier gene selection by diversifying the population.
