The species name aestiva comes from the Latin aestīvus and means "of the summer" or "summery" which could refer to its active season or its green coloration. If you put the name together, Philodryas aestiva roughly means "summer-loving tree snake" or "summery tree-dweller", hinting at its habitat and activity patterns.
Philodryas aestiva inhabits a wide range of environments in southwestern Brazil, northern Argentina, Paraguay, Bolivia, and Uruguay. They prefer open forests and savannahs (such as the Cerrado biome in Brazil) but are sometimes found in semi-urban or rural areas.

No species of the same family or order lives in Emas National Park, so these are its closest relatives here: other reptiles.
Possible
About 30% of wildlife watchers report a Brazilian Green Racer sighting in Emas National Park on a given day, based on 14 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 7th most-seen of the 11 reptiles we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
February
In that month about 50% of wildlife watchers report a Brazilian Green Racer in Emas National Park on a given day, against under 5% in March to July, the lowest months. That is one of Emas National Park's wettest months, with about 170 mm of rain against almost none in July.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Brazilian Green Racer sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Emas National Park, in our data
Emas National Park is the only park on Wallace's Line with enough records to rate Brazilian Green Racer sightings: about 30% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Brazilian Green Racer is recorded against all the reptiles logged in Emas National Park (14 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.
