What does a common swift sound like?
The Common Swift (Apus apus) is known for its characteristic, high-pitched calls, often described as a piercing "scream." These vocalizations are typically heard in flocks as they swoop and dash through the sky, particularly during the breeding season. Their primary call is a sharp "sreee" or "srii," emitted in rapid succession, creating a continuous "screaming party" sound. Unlike many birds, swifts do not have a complex song, as their calls primarily serve in communication and social cohesion within groups rather than for territory establishment or mate attraction.
Description
Common swifts are pretty fly. Literally – they spend most of their lives in the air. They can eat, sleep and mate on the wing, and spend as much as 10 months flying non-stop. They don't really have a call, so much as a loud scream and, on summer evenings, they will form screaming parties. Relatable, am I right?
The common swift can weigh between 30to50grams and be from16to17centimeters tall.
The typical lifespan of the Common Swift (Apus apus) is around 5 to 21 years, with some individuals recorded living up to 26 years. This longevity is exceptional compared to many bird species, partly due to their aerial lifestyle, which reduces predation risk. They exhibit high survival rates once they reach adulthood. In comparison, the Alpine Swift (Tachymarptis melba), a related species, can live up to 26 years as well, while smaller swifts like the Chimney Swift (Chaetura pelagica) typically have shorter lifespans, often around 5 years, due to different environmental pressures.

How to recognise a common swift?
Common swift identification guide
General appearance: The Common Swift, scientifically known as Apus apus, is primarily recognized by its long, slender, sickle-shaped wings and streamlined body. Its plumage is typically dark sooty brown, which often appears black when viewed against the sky. The bird's throat is slightly lighter, providing a subtle contrast to its overall somber coloring. With a short tail and a broad, slightly forked appearance, the Common Swift exhibits a sleek and aerodynamic figure optimized for fast, agile flight. Male vs female: The Common Swift exhibits minimal sexual dimorphism, meaning males and females look remarkably similar. Both sexes share the same size, wing shape, and coloration, making them difficult to differentiate unless observed under specific conditions such as behavioral patterns during the breeding season. Juvenile: Juvenile Common Swifts resemble adults but are often distinguishable by their slightly duller plumage. Their feathers may not have the same glossy sheen as those of mature birds. Additionally, juveniles may have pale edgings to their feathers, which gives them a slightly scaly appearance. This scaly pattern can help in differentiating younger birds from fully matured adults, particularly when observed in mixed-age flocks.

Chimney Swift vs Common Swift
The Chimney Swift is similar to the Common Swift in terms of its body shape and rapid flight. However, the Chimney Swift is slightly smaller and has a more squared-off tail compared to the forked tail of the Common Swift. They are often distinguished by their 'flying cigar' appearance and chittering calls.
Breeding and nesting habits of the common swift
Mating behaviors
Common Swifts exhibit aerial courtship displays, often swooping and gliding gracefully in the sky. They are highly social during breeding, forming large flocks known as "screaming parties," which serve as both courtship and territorial displays. Swifts are monogamous and often return to the same nesting sites with the same mate for several years.
Nesting details
Nesting occurs in secluded cavities, often in buildings, cliffs, and other structures with sheltered nooks. Swifts use available materials such as feathers, plant fibers, and saliva to construct their nests. They prefer nesting sites that offer safety from predators and harsh weather conditions. In gardens, creating an inviting habitat involves installing swift nest boxes high on buildings away from direct sunlight and ensuring minimal disturbance.
Eggs and chick-rearing
Females lay 2 to 3 white eggs, which are incubated by both parents for about 19 to 20 days. Upon hatching, the altricial chicks are fed a diet of insects caught in flight, requiring frequent feeding by both parents. The chicks remain in the nest for around 6 to 8 weeks before fledging. Once they learn to fly, the young are almost immediately independent, undertaking long migrations just weeks after leaving the nest.

Natural Diet
The Common Swift (Apus apus) primarily feeds on flying insects and airborne spiders. Their diet consists mainly of beetles, flies, aphids, and planthoppers, which are caught during their agile flight. These birds exhibit remarkable aerial skills, enabling them to snatch their prey mid-air. Their dietary habits are influenced by seasonal changes, with an abundance of different insects available during warmer months, making it easier for swifts to obtain the necessary nourishment. During the breeding season, swifts are particularly reliant on protein-rich insects to feed their young, ensuring they receive adequate nutrition for growth and development.
Bird Feeders
Common Swifts are not typical candidates for most bird feeders, given their specific dietary needs. Unlike many garden birds that frequent feeders for seeds or nuts, swifts stick to their natural prey of insects and do not generally consume offerings from feeders. Attracting swifts to gardens involve creating an insect-friendly environment, such as maintaining native plant species that support a diverse insect population. Providing access to water bodies can also help, as they offer a natural hunting ground for these aerial experts. Overall, while swifts do not associate with bird feeders, eco-friendly gardening practices can support their natural foraging behaviors.
Choose a bird friendly feeder for swifts
Common Swifts are not frequent visitors to traditional feeders, so instead opt for structures where they can nest comfortably. Install Swift boxes or colony systems, which provide a safe space for these birds during the breeding season. Sustain their natural habitat needs by encouraging them to take up residence around your home.
Offer swift-friendly snacks to entice visitors
While Swifts primarily feed on insects, you can attract them with appetizing alternatives. Bird Buddy seeds, packed with the best nutrients, can draw other insects that Swifts will pursue. Plant native flowers and keep insect-friendly environments that suit their diet preferences, making your yard their go-to spot.
Optimal feeder placement and height for swift success
Place Swift nesting boxes at least 5 feet above the ground to simulate their natural nesting environment. Ensure these boxes are protected from harsh weather and predators, maximizing their chance of attracting Swifts. Consider placing them near open spaces for easy access during high-speed flights.
Seasonal timing is crucial for swift nesting
Common Swifts migrate annually, so aim to set up any feeders or nesting boxes well before their return, typically by early spring. Maintaining these structures year-round will ensure they're available when the Swifts arrive, offering them a ready-made residence for their breeding season.
Enhance your yard with water and habitat features
Swifts need water for drinking and preening, so introduce bird baths or water features as part of your garden. Plant tall trees and maintain varied shrubbery; such elements create a haven for insects Swifts love to feast on and offer the birds a place for relaxation and refuge throughout their visit.
