The swallow tanager (Tersina viridis) is a species of Neotropic bird in the family Thraupidae, the tanagers and allies. It occurs regularly in Panama, on Trinidad, and in every mainland South American country except Chile and Uruguay. It has occurred as a vagrant in those two countries and on Tobago and Bonaire and there are unconfirmed reports from Curaçao.
The swallow tanager was formally described in 1811 by the German zoologist Johann Karl Wilhelm Illiger with the binomial Hirundo viridis, mistakenly classifying it as a swallow. The type locality is eastern Brazil. The species is now the only member of the genus Tersina that was introduced in 1819 by the French ornithologist Louis Pierre Vieillot. The genus name is from the French Tersine, an unidentified bird described by Georges-Louis Leclerc, Comte de Buffon. The specific epithet viridis is the Latin for "green". Some mid-twentieth century authors placed the genus in its own family, Tersinidae. A molecular phylogenetic study of the tanager family published in 2014 found that the swallow tanager is a Thraupidae tanager and is sister to the honeycreepers in the genus Cyanerpes.

It is the 116th most-seen of the 149 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
January, March and September
In those months about 10% of wildlife watchers report a Swallow Tanager in Campinas on a given day, against under 5% in February, April–August and October–December, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Swallow Tanager sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
7th of 11
Of the 11 cities where we can rate Swallow Tanager sightings, Campinas ranks 7th at under 5%. The best odds are in Campo Grande (Brazil, about 20%), Curitiba (Brazil, about 10%) and Goiânia (Brazil, about 10%).
Same family: Thraupidae
The closest relatives of the Swallow Tanager that you can see in Campinas (family Thraupidae, Tanagers and Allies) are Sayaca Tanager (about 80%), Bananaquit (about 50%) and Palm Tanager (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Swallow Tanager is recorded against all the birds logged in Campinas (10 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.
