The scissor-tailed nightjar (Hydropsalis torquata) is a species of nightjar in the family Caprimulgidae. It is distributed over much of eastern South America. The scissor-tailed nightjar was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the other nightjars in the genus Caprimulgus and coined the binomial name Caprimulgus torquatus. The scissor-tailed nightjar is now placed with three other species in the genus Hydropsalis that was introduced in 1832 by the German naturalist Johann Georg Wagler. The genus name combines the Ancient Greek hudro- meaning "water-" with psalis meaning "pair of scissors". The specific epithet torquata is from Latin torquatus meaning "collared".
Two subspecies are recognised: The specific epithet brasiliana or brasilianus was formerly sometimes used. The most distinctive feature of the scissor-tailed nightjar is the male's elongated outer tail feathers... Wikipedia →

Rare
Under 5% of wildlife watchers report a Scissor-tailed Nightjar sighting in São Paulo on a given day, based on 148 verified sightings from GBIF citizen-science data. It is the 176th most-seen of the 353 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Scissor-tailed Nightjar in São Paulo on a given day, so our monthly data shows no clear season.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Scissor-tailed Nightjar sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is seen both by day and at night.

Of the 3 cities where we can rate Scissor-tailed Nightjar sightings, São Paulo ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Cordoba (Argentina, under 5%) and Buenos Aires (Argentina, under 5%).
GBIF citizen-science records
It is estimated from how often the Scissor-tailed Nightjar is recorded against all the birds logged in São Paulo (148 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.
