The short-tailed swift (Chaetura brachyura) is a bird in the Apodidae, or swift family. The species was first formally described as Acanthylis brachyura in 1846 by the Scottish naturalist Sir William Jardine, based on the observations of Mr. Kirk, a resident of Tobago.
The genus name Chaetura is derived from the Greek khaite (hair) and oura (tail). The specific epithet brachyura is Greek for brakhus (short) and ouros (tailed). Four subspecies are recognized: C. b. praevelox, found in Grenada, Saint Vincent, and Tobago

Rare
Under 5% of wildlife watchers report a Short-tailed Swift sighting in Tayrona National Natural Park on a given day, based on 24 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 191st most-seen of the 285 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
July and November
In those months about 10% of wildlife watchers report a Short-tailed Swift in Tayrona National Natural Park on a given day, against under 5% in August–October and December–June, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Short-tailed Swift sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
17th of 19
Of the 19 parks where we can rate Short-tailed Swift sightings, Tayrona National Natural Park ranks 17th at under 5%. The best odds are in Main Ridge Forest Reserve (Trinidad and Tobago, about 30%), Yasuní National Park (Ecuador, about 30%) and Soberanía National Park (Panama, about 20%).
GBIF citizen-science records
It is estimated from how often the Short-tailed Swift is recorded against all the birds logged in Tayrona National Natural Park (24 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
