Panyptila cayennensis

Lesser Swallow-tailed Swift

(Gmelin, 1789)

Detailed Texts Multi-lang
A medium-small, elegant swift with a highly aerodynamic silhouette, characterized by a long, deeply forked tail that is often held tightly closed like a needle. Its plumage is predominantly glossy blue-black, contrasting sharply with a white throat, upper breast, patch on the flanks, and a white collar wrapping around the hindneck.

Yes

Habitat SummaryOverview of the specific ecosystems and environments where this species is found in Costa Rica. Multi-lang

Forages in the open skies over humid lowland forests, secondary growth, clearings, and occasionally urban areas. It nests and roosts on vertical structures, including tree trunks, palm fronds, cliffs, and the walls of buildings.

BehaviourDaily activity patterns, movement, territory use, foraging style, and seasonal behavioral changes. Multi-lang

An aerial specialist that spends nearly its entire active day aloft. They are incredibly fast fliers, usually foraging at higher altitudes than most other swifts, coming lower only during overcast weather or rainfall.

Social ActivitySocial structure: whether the species is solitary, paired, or colonial; hierarchy and communication. Multi-lang

Often observed in pairs or small family groups. They may occasionally join larger mixed-species foraging flocks of other swifts and swallows high in the air, but remain cohesive with their partner.

Feeding GuildWhat the species eats, how it forages or hunts, and its role as a consumer in the food web. Multi-lang

Diurnal aerial insectivore.

Trophic Chain DetailsSpecific interactions in local food webs: prey species, predators, competitors, and scavengers. Multi-lang

Strictly insectivorous, feeding on small winged insects caught entirely on the wing, such as flying ants, termites, small beetles, and true bugs (Hemiptera) that are swept up into thermals.

Reproductive BehaviourMating strategies, courtship displays, nesting or spawning behavior, and parental care. Multi-lang

Both parents contribute equally to gathering material on the wing and constructing the long tubular nest, a process that can take many months. Due to the high investment in nest building, the structure is actively maintained and reused over multiple years.

Lifespan EstimatedExpected duration of life from birth to natural death under wild conditions.
Males4 - 7 Years
Females4 - 7 Years

Evolutionary AdaptationsInherited traits and behaviors that improve the species' survival and reproduction in its specific environment. Multi-lang

Extremely long, narrow wings and a deeply forked tail allow for precise, high-speed banking maneuvers in the open air to capture fast-flying insects.
Highly developed salivary glands that produce a sticky, cement-like saliva used to bond airborne plant fibers and seeds together into a sturdy, free-hanging structure.

Main ThreatsDocumented pressures reducing the population: habitat loss, hunting, disease, climate change, and invasive species. Multi-lang

Widespread use of aerial pesticides in agriculture, which drastically reduces the abundance of aerial plankton (flying insects) that the species relies on.

Interesting FactsSurprising or notable facts that highlight what makes this species unique or ecologically important. Multi-lang

Their nests are marvels of bird architecture; they build a large, felted vertical sleeve up to 60 cm long that hangs from a surface, featuring a false entrance at the bottom to confuse predators, while the real entrance sits safely higher up inside.
