22 Interesting Kingfisher Facts: You Should Know

Measuring only 12cm in height, adorned with striking blue feathers, and zipping through the air like a bullet, a kingfisher is certainly impressive. However, despite its stunning appearance, this bird is highly secretive.

With their ability to plunge into the water to spearfish, and their brightly-colored feathers shimmering like the streams they perch above, kingfishers are easily distinguishable. These distinctive birds can be found across the globe and provide an entertaining spectacle to observe.

This article is on some interesting facts about kingfishers and their exceptional qualities that set them apart from other creatures in the animal kingdom.

Facts About Kingfisher

Kingfishers’ Distribution Across Continents:

Kingfishers are on every continent except Antarctica, with the highest species concentration in Southeast Asia and the Australian islands. Most species are located in the Old World’s eastern regions, encompassing Asia, Africa, and Australia.

 Despite this, a few species have also made their home in Western Europe and the Western Hemisphere. The Americas are home to only six kingfisher species, while Europe has only three species.

Unique Nesting Habits of Kingfishers:

Kingfishers have unique nesting habits to protect their young. They build their nests in underground burrows or tree cavities near water sources. Both males and females excavate tunnels to create a secure chamber for their eggs and chicks. 

The burrows are disguised in the riverbank, and the kingfishers fly directly into them. Those who prefer tree cavities select trees near the water for easy access to food.

Categories Kingfishers Based on Habitat and Diet:

There are three categories of kingfishers based on their habitat and diet. Tree kingfishers rely less on water and feed on small creatures, while river kingfishers consume fish and other creatures and nest near water sources.

Water kingfishers have a similar diet to river kingfishers but rely solely on fish and nest in burrows near water sources.

Exploring the Global Distribution of Kingfishers:

Kingfishers are found on every continent except Antarctica, and they thrive in areas with water such as freshwater rivers, streams, and wetlands. Some also inhabit coastal marshes with a mix of saltwater and freshwater. 

The distribution of kingfishers around the world varies depending on their subfamily. While water kingfishers are only found in North America, river and tree kingfishers can be found in Asia, Europe, sub-Saharan Africa, and Australia.

The adaptability of Kingfishers to Human Development:

Kingfishers are known to utilize human-made canals and waterways for fishing, nesting, and raising their young. However, certain human activities, such as channelization, can negatively affect their habitat. It destroys the kingfisher’s perching foliage, limits fish survival, and buries nesting habitats. 

Although they are not drawn to bird feeders, you might spot them near rural streams during morning or evening walks. A possible title for this content could be “Kingfishers and their adaptability to human-made waterways.

Similarity Between Male and Female Kingfishers:

Most Kingfisher species do not display sexual dimorphism, where males and females of the same species appear similar. Only some species exhibit such differences in appearance between genders. Even among those sexually dimorphic kingfishers, the variations in appearance are often minimal. 

For instance, the female Belted Kingfisher looks nearly identical to the male, except for a single distinguishing copper band across her chest.

Kingfishers’ Hunting Technique and Feeding Habits:

Kingfishers use their sharp bills and strong muscles to impale their prey. They dive at high speed into streams and rivers, aiming at their prey.

When the prey is impaled on their bill, they can’t escape. Kingfishers then eat their prey whole. Some may beat the fish against a rock or limb to kill it before swallowing it.

Kingfishers’ Active Time:

Kingfishers are known to be most active during dawn and dusk, which are the high-activity times in the animal kingdom.

As they rely on the movement of fish and invertebrates to hunt and catch their meals, cooler temperatures and active prey during these times offer an advantage. Moreover, staying hidden in the shadows during these times helps the kingfisher to avoid frightening its prey.

Kingfishers: Masters of Ambush Predation:

Kingfishers are skilled ambush predators that patiently wait for their prey before striking. Perched on a branch over the water, they use their sharp eyesight to detect movement below the surface.

When the opportunity arises, they dive at high speed, impaling or grabbing their prey with precision. This hunting technique requires patience, fast flying skills, and excellent eyesight.

Kingfishers: The Masters of Ambush Hunting:

Kingfishers’ heads and bills are disproportionately large compared to their bodies, but this is an adaptation that helps them hunt.

Their strong neck muscles and enlarged skulls protect their brains during high-impact dives while their powerful eyes locate prey under the water. They also have the ability to keep their heads still while perching on a moving branch, known as vision stabilization.

The hydrodynamic design of kingfisher beaks and its impact on technology:

Kingfishers possess hydrodynamic beaks that are ideal for their diving techniques. Their long, pointed, wedge-shaped beaks create minimal noise and water disruption, slicing into the water without alarming the fish.

Had they possessed rounder beaks, like ducks, they would have slowed down, allowing the fish to escape. Japan recognized the efficiency of this design and imitated it for their bullet train, thereby reducing wind noise and increasing speed.

The Digestive Superpower of Kingfishers:

Kingfishers possess strong stomach acid that helps them digest their prey’s bones, scales, and shells. While the chicks are born with extremely powerful stomach acid, adult kingfishers spit up bone pellets like owls. These pellets provide valuable information for scientists to study the diet of kingfishers.

The Belted Kingfisher:

The Belted Kingfisher is the only species of kingfisher commonly found in the United States. They can be spotted throughout most of the country all year round.

During the breeding season, some travel north to Canada and Alaska; in winter, they move south to the southern U.S. and Mexico. These water-loving birds can be seen near streams, shorelines, and ponds with abundant fish supply.

Monogamous Kingfishers: Raising Chicks Together:

Kingfishers are monogamous during the breeding season and form new pairs each year. Once paired, they work together to dig burrows or furnish nest cavities and hunt and incubate their young.

In some species, only the female incubates the eggs. Both male and female kingfishers are fiercely territorial and defend their territory together against other kingfishers.

The impressive visual prowess of Kingfishers for underwater hunting:

Kingfishers possess remarkable vision abilities that enable them to detect and capture prey underwater. Although water distorts the perception of distance, the birds are skilled at estimating the exact location of their target.

The sacred kingfisher, for instance, can spot prey up to 55 feet away with precision. Their hunting prowess is attributed to their sharp eyesight, which helps them locate and hunt prey accurately.

Consuming Large Prey with Small Beaks:

Despite having relatively small beaks, kingfishers can consume prey that appears larger than their beak size. The Amazon kingfisher, with a beak measuring only 2.7 inches (7cm), can devour fish up to 6.6 inches (17cm) in length.

The Versatile Diet of Kingfishers:

Kingfishers are not limited to eating fish and are known to prey on snails and frogs as well. Their diet varies based on their habitat, with some species consuming insects, spiders, reptiles, and even small mammals. Whether residing in forests, grasslands, or deserts, kingfishers adapt their feeding habits accordingly.

The Beauty Rituals of Kingfishers:

Kingfishers are conscious of their appearance, which is understandable given their stunning plumage.

They enjoy bathing and drying themselves in the sun and meticulously groom their beaks on branches until satisfied with the result. These little birds seem to have a sense of vanity, taking pride in their well-groomed appearance.

The Sturdy Feet of Kingfishers:

Although kingfishers spend most of their time perching on branches or stems, they have short legs and strong feet that can tightly grip their perches.

The Hygiene Habits of Kingfishers:

Kingfishers have a penchant for cleanliness and maintain it by diving into the water to bathe and then drying themselves in the sun while preening their feathers.

Some kingfishers also use their wings to scrub and scratch their heads. They keep their bills clean by scraping them against branches until they are content with their bill’s condition.

Japanese Bullet Trains Took Inspiration from Kingfishers:

Scientists are fascinated by kingfishers for their speedy flight that can reach up to 25 miles per hour and their uniquely designed beaks.

With sharp and elongated beaks that make up one-third of their height, kingfishers can effortlessly dive into water without disturbing fish. 

This remarkable feature has caught the attention of engineers working on Japan’s high-speed bullet train, who have adopted the shape of the kingfisher’s beak to prevent sonic booms when the trains enter tunnels.

Ugly Ducklings Turn into Beautiful Kingfishers:

Upon hatching, kingfisher chicks, with their bald and pink appearance, are far from attractive. Measuring only one inch in height, they sit upright like mini pterodactyls, relying on each other for balance.

This close-knit arrangement helps keep them warm and dry while their posture prevents contact with the dirty nest floor. Unlike other bird species that maintain cleanliness by removing their chick’s excrement, kingfisher nests can be quite dirty. Consequently, their flight feathers don’t develop until a week before hatching.

However, once their striking blue and orange plumage emerges, these “ugly ducklings” become magnificent kingfishers.
