Birds are some of the most prominent creatures on Earth, offering us an incredible opportunity to closely observe their feeding behaviors. These behaviors often include some of the most bizarre and unsettling actions in the animal kingdom. In this captivating yet occasionally disturbing exploration, we’ll examine truly unusual avian hunting methods, including the predatory parakeets, the eccentric Black Skimmer, and Russia’s fish-eating owls, among others.
10. Black Heron
Herons are known for their stealthy hunting techniques, often moving silently through the shallows of coastal marshes to catch surprisingly large fish. However, the Black Heron of central Africa's wetlands has abandoned the traditional approach in favor of a deceptive tactic. In a scene reminiscent of an Aesop's Fable, the Heron spreads its wings in a circular formation, casting a shadow over the water that resembles a palm tree. Small fish, like tetras, mistakenly swim toward this shadow, seeking refuge, only to meet their end when the heron’s bill strikes down from the 'canopy.' The Black Heron repeats this deadly routine at various locations throughout the day.
9. Black Skimmer
Closely related to Gulls and Terns, yet bearing a striking resemblance to a seafaring toucan, the remarkable Black Skimmers are the only bird species with a lower bill that extends beyond the top. With the bottom mandible reaching up to three inches beyond the upper bill, this unusual feature enables the skimmer to employ a unique feeding method. Soaring at speeds of over 40 kilometers per hour, the skimmer drags its elongated lower bill through the water, snapping it shut whenever it detects a small fish. Often hunting in pairs, these birds must skillfully maneuver to avoid obstacles, creating a scene that could rival the most intense action movie. However, danger lurks: on rare occasions, a skimmer’s bill may collide with submerged debris, resulting in injury.
8. Antipodes Island Parakeet
Among all parrots linked to piracy, the Antipodes Island Parakeet might just be the most appropriate. Native to New Zealand’s Antipodes Islands, this 12-inch cousin of the pet Budgerigar appears to be the classic green parrot, but behind its unassuming exterior lies a darker truth. On the Archipelago, Grey Storm-Petrels nest in burrows along the shore. The parakeets, however, dig apart these burrows, where the robin-sized relatives of shearwaters and albatrosses hide, and proceed to kill them with their sharp, hooked bills before consuming them. Despite its seemingly harmless appearance, the Green Parakeet is also a scavenger, feasting on any dead seabirds it encounters along the coast. As a true parrot, it also feeds on fruits and seeds.
7. Fish Owl
When we think of owls, we often envision secretive, nocturnal forest hunters that prowl in the dark for rabbits, skunks, and mice. However, Blakiston’s Fish Owl hunts in the shadows of wetlands and forested rivers, targeting fish. With an impressive wingspan of six feet and weighing over 10 pounds, it is the largest owl in the world, specially adapted to catch fish with spikes on its foot pads. As it swoops down, the spines quickly sink into its fish prey, and the well-insulated owl lifts it out of the water. Unfortunately, deforestation along riverbanks harms both fish habitats and vital roosting sites, putting this rare bird of prey at risk.
6. Golden Eagle—Cliff Pusher
Regarded as the true King of Birds, Golden Eagles are featured on numerous national emblems and play an ecological role in the bird world akin to that of lions. With a wingspan reaching up to 9 feet, these 15-20 pound birds are found throughout the northern hemisphere, residing in mountainous and foothill regions, where they can establish territories as large as 60 square kilometers. While most raptors prey on animals smaller than themselves, such as rabbits and ducks, Golden Eagles use their remarkable strength, size, and agility to hunt large mammals. By diving down steep mountainsides, they extend their powerful talons to snatch mountain sheep or ibex, briefly carrying them before throwing them off cliffs to kill them. If cliffs aren’t available, the eagles may descend into forests and simply crush a deer to death. However, they rarely pose a threat to livestock.
5. Japanese Hooded Crow
Some birds employ unusual foraging methods not due to specific adaptations, but because of their incredible intelligence and ability to thrive in human-influenced environments. Among these clever species is the Japanese Hooded Crow, which faced a challenge in accessing hard-shelled ornamental tree nuts. Lacking the strength to break them by dropping them from the air, these resourceful crows came up with a brilliant solution: they wait for a red traffic light, walk into the crosswalk, and place the nuts in the path of approaching car tires. When the cars roll forward, the nuts are crushed, allowing the crows to retrieve their food once the light turns red again. The amount of foresight involved in this behavior is remarkable, and it further supports the theory that crows, not parrots, may be the smartest birds.
4. Bat Falcon
In Mexico and Central America, ancient limestone caves seem to erupt with clouds of black smoke every evening, as massive flocks of Mexican Free-tailed Bats emerge to hunt forest midges. But in this case, nature’s cycle allows the hunters to become the hunted. The Bat Falcon, a small but fierce raptor, has adapted to focus on winged mammals instead of the typical prey of small birds. Equipped with specialized night vision, the Bat Falcon zooms through bat flocks, snatching one bat at a time by the wing during each feeding pass and carrying it to a perch, where it methodically dismembers the prey. When bats are scarce, the falcon also captures insects and finches. Interestingly, another bird species has also evolved to rely on bats for food, and as birds, falcons are immune to the risk of rabies.
3. Great Black Backed Gull
Unlike the majority of the 45 gull species, the Great Black Backed Gull possesses a combination of size, strength, and agility that makes it more similar to a raptor than a typical gull. With a wingspan of six feet, Larus marinus – literally translated as 'Sea gull' – is the largest gull species in the world, and by far the most fierce. Although it lacks talons, this aggressive bird dives at jet fighter-like speeds in pursuit of prey such as puffins, ducks, and even other gulls, which it captures with its massive bill before swallowing them almost whole. If the prey manages to escape the initial dive, the Great Black Backed Gull can execute a remarkable, aircraft-like 4 G loop and make another pass. No bird matches this predator’s incredible maneuverability, and few are as relentlessly aggressive.
2. Pied Oystercatcher
Unlike most sandpipers that use their sharp bills to probe the sand for shrimps, snails, and mudworms, the Haematopedia, or Oystercatchers, have a unique approach to foraging. Equipped with a razor-sharp, solid red bill, the Black Oystercatcher – the most aggressive species – roams rocky shorelines in search of mussels, clams, and oysters. The bird then inserts its bill sideways through the shell, severing the muscle that holds it closed. Interestingly, some Oystercatcher populations seem unaware of this technique and resort to brute strength, smashing the shells open instead. Once they’ve broken through, they use their straw-like bills to suck out the contents.
1. Ivory Gull—the Dung Bird
While most gulls scavenge for dead crabs, fish, and detached mussels along shorelines, one species takes scavenging to an extreme. Inhabiting the harsh northern regions of the Canadian and Russian Arctic, the Ivory Gull patrols the icy sheets of the land of the midnight sun, where it has adapted to an unusual diet. During winter, when food is scarce, this seabird turns to seal and fox excrement, and even the afterbirth of mammals, in order to survive. This strange diet provides essential protein for the gull, which, despite its peculiar feeding habits, is quite a beautiful bird. Unfortunately, the Ivory Gull is now endangered due to the presence of introduced predators. Its powerful digestive system allows it to safely consume contaminated materials that would harm most other birds.
