Sick's swift (Chaetura meridionalis) is a species of swift in the family Apodidae. It was previously considered conspecific with the smaller ashy-tailed swift, but a study published in 1997 found that Sick's swift was closer to the chimney swift. The English name commemorates the German-born ornithologist Helmut Sick who studied South American birds. It is a migratory species that breeds in central South America and overwinters in northern South America. The IUCN has listed it as being of "Least Concern".
Sick's swift was formally described in 1907 by the Austrian ornithologist Carl Eduard Hellmayr from specimens collected in the Santiago del Estero Province of northern Argentina. Hellmayr considered it to be a subspecies of the ashy-tailed swift and coined the trinomial name Chaetura andrei meridionalis. The specific epithet is a Latin word meaning "southern". Based on a study by the ornithologist Manuel Marín, Sick's swift is now considered to be separate from the ashy-tailed swift and has been elevated to species status. The English name commemorates the German-born ornithologist, Helmut Sick, who studied Brazilian birdlife.

Possible
About 20% of wildlife watchers report a Sick's Swift sighting in Campinas on a given day, based on 83 verified sightings from GBIF citizen-science data. It is the 40th most-seen of the 149 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
September and December
In those months about 30% of wildlife watchers report a Sick's Swift in Campinas on a given day, against under 5% in May to July, the lowest months.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most Sick's 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.
7th of 15
Of the 15 cities where we can rate Sick's Swift sightings, Campinas ranks 7th at about 20%. The best odds are in Porto Alegre (Brazil, about 40%), Salvador (Brazil, about 40%) and Curitiba (Brazil, about 30%).
GBIF citizen-science records
It is estimated from how often the Sick's Swift is recorded against all the birds logged in Campinas (83 verified sightings), 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.
