20 Fascinating Facts About Swift Birds

Facts About Swift Birds

Swifts are extreme aerial entertainers known for their tiny, slender physiques and exceptional flying abilities. These birds spend most of their lives flying; they also rest and mate while on the wing. Swifts are ideal for a lifetime of continuous flight due to their unique shape, large swept-back wings, and short forked tails. We will explore 20 fascinating facts about swift birds that will amaze and educate you.

Things to know about Facts About Swift Birds

What kind of bird is a swift?

The swifts are a family, Apodidae, of highly aerial birds. Though superficially resembling swallows, they are not closely related to any passerine species. Swifts are instead placed in the order Apodiformes, which also includes hummingbirds.

What does a swift bird look like?

Slender swifts have blackish-brown plumage, a white neck patch, lighter under and inner wings, a rump, and a face. Sharply forked tail, long, pointed wings, black bills with massive gaps, and dark brown eyes. Juvenile black swifts have bigger white neck and forehead feathers. Swifts, which appear like swallows but have a torpedo-shaped body, small beak, long, thin wings, short tails, and no legs, are considered flight experts and feed on flying insects.

Swifts build nests from sticks and saliva

Swifts construct their nests using a unique blend of sticks and saliva. It is a material well-suited for adhering to rough surfaces like brick. This makes the chimney of the Log House an ideal nesting site for these birds. However, modern chimneys are often capped and lined with smooth steel. It is proving too slick for swifts to effectively build their nest.

Swifts have a unique shape

Swifts are easily distinguished from swallows and martins by their larger size and distinctive sickle-shaped wings. Their call, often described as a piercing “scream”, is another telltale sign of these aerial specialists.

swifts are incredible flying flyers

Swifts are exceptional fliers that combine great speed, agility, and endurance. Their flight is breathtaking to see.

Swiftest fastest birds in the world

Swifts are without a doubt among the fastest birds on the planet, with the common swift and white-throated needletail being two of the fastest level-flying birds known. Their particular modifications help them to be excellent aerial entertainers. Held by the common swift Although some species may reach speeds of over 200 kilometers per hour (124 mph), the record for the fastest known level flight by a bird is 111.5 kilometers per hour (69.3 mph).

Swifts are fascinating birds that are a joy to watch in flight.

As some of the fastest level-flying birds, swifts can reach speeds over 100 mph. The common swift and white-throated needletail are among the speediest, leaving onlookers in awe of their sheer velocity.

Where do swifts live?

The soft-tailed blackish-brown bird, known simply as “swift” in Britain, ranges throughout Eurasia and winters in southern Africa. It nests in buildings and hollow trees. While six Apus swifts live in South America, nine more live in temperate regions of the Old World.

Swifts are found all over the world

Swifts are found on every continent except for Antarctica, southern Chile and Argentina, New Zealand, and the majority of Australia. Swifts, which resemble swallows, range in size from the little 9 cm pygmy swiftlet to the large 23 cm purple needletail.

How many species of swifts are there?

There are roughly 113 Swift species worldwide, eight of which may find themselves in the UK. The Common Swift, Apus apus, is one of our most regular summer visitors. There are three primary groups: true swifts, tree swifts, and needletails.

what do swifts eat?

Swifts eat many flying insects. Their meal consists of dragonflies, flies, ants, aphids, wasps, bees, and even flying spiders, which they quickly seize in mid-flight with their unique beaks. Some rapid species, such as the chimney swift, feed in mixed flocks with airborne insectivores like swallows to increase foraging efficiency.

How long do swifts live?

Swifts short and fast-flying existence. They have a remarkably long lifespan. Swifts can live for up to 21 years, though the average lifespan is around 5.5 years. The oldest known swift was at least 19 years old when it was retrapped alive.

Why do swifts scream?

Summer nights provide colorful “screaming parties” from swifts. Groups of 10 to 20 birds will gather in flight around their nesting places, calling out and receiving responses from their nestmates. Larger “screaming parties” might form at higher elevations, particularly at the end of the mating season.

What are the different vocalizations used by swifts

Swifts are highly vocal, communicating both acoustically and visually. Males and females have distinct calls, ranging from high-pitched chips to rattling, buzzy screams. Males also perform elaborate aerial displays to attract mates and ward off rivals.

Where do swifts nest?

Swift birds are quite good at hiding in the clefts of man-made things. They often nest under the roofs of homes, churches, and other structures, squeezing through even the slightest spaces to reach their comfortable chambers. However, as more old buildings are restored and soffits covered, the number of suitable fast nesting sites is rapidly decreasing.

How do swift birds sleep?

Swift birds, like other animals, need sleep, which they may get while flying. Scientists, inspired by dolphins and frigatebirds, propose that swifts sleep in either bihemispheric mode (with both hemispheres temporarily offline) or unihemispheric mode (with only one cerebral hemisphere asleep at a time).

Given that swifts spend an incredible 6–10 months aloft before returning to reproduce, the ability to sleep on the wing is essential. Nonetheless, compared to the 12 hours they spend on land, they sleep relatively little—an average of 42 minutes per day.

Where do swifts migrate to?

Swifts come to the UK in April to breed before leaving in late summer for Sub-Saharan Africa. However, the period of their journey may be altering in response to climate change. It is impacting their behavior and reproductive habits.

Do swifts ever land?

Swifts spend most of their time flying. After fledging, they only return to their nests to feed their young, having begun reproducing when they were two to three years old. Swifts spend the majority of their time in flight foraging, mating, gathering nesting materials, and even resting.

Swifts bird that spends the most time in the air

According to current studies, pallid swifts may fly for more than three months without touching down. Lund University researchers revealed that the pallid swift may fly for two to three and a half months without landing.

White-Throated Swifts Are Not Picky About Nesting Sites

Swifts’ breeding behaviors have evolved to take advantage of human-influenced environments. Although they typically nest in rock fissures, they have quickly adapted to the nooks and corners of buildings, bridges, highway overpasses, and even quarries.

Their breeding habitats span from the lowest elevations—Death Valley, 180 feet below sea level—to more than 11,000 feet in the highlands. This adaptability has allowed swifts to flourish in both natural and man-made environments.


Swifts are fascinating creatures that have captivated the attention of animal enthusiasts for centuries. These agile birds possess numerous remarkable attributes that allow them to thrive in the skies.

From their remarkable flying abilities and migration patterns to their unique nesting habits, swifts are truly extraordinary creatures. We need to recognize and appreciate the role swifts play in our ecosystems. By understanding their behavior and habitat needs, we can work towards their conservation and ensure their survival for future generations to marvel at.
