Oxybelis aeneus, commonly known as the Mexican vine snake or brown vine snake, is a species of colubrid snake, which is endemic to the Americas. Oxybelis aeneus is found through southern Mexico, to northern South America and Trinidad and Tobago. There is no loreal scale, and there are 8–10 upper labials.
The smooth dorsal scales are arranged in 17 rows at midbody. Ventrals 173–205; subcaudals 150–188, divided (paired). The anal plate is divided in Arizona specimens, but is entire in South American specimens. In Arizona O. aeneus is also called "pike-headed tree snake". In Trinidad and Tobago and Guyana, it is known as a "horse whip" or "vine snake". Mostly arboreal and diurnal, O. aeneus is quite often mistaken for a vine. When threatened, it sometimes releases foul smelling secretions from its vent.
Oxybelis aeneus feeds mainly on lizards (mostly anoles), but also eats frogs, small rodents and birds. Oxybelis aeneus is a mildly venomous rear-fanged snake, but it is not considered dangerous to humans. Oxybelis aeneus is oviparous. Clutch sizes of 3–6 have been published. In... Wikipedia →

No species of the same family or order lives in João Pessoa, so these are its closest relatives here: other reptiles.

About 20% of wildlife watchers report a Brown Vinesnake sighting in João Pessoa on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 13th most-seen of the 15 reptiles we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.

Of the 5 cities where we can rate Brown Vinesnake sightings, João Pessoa has the highest daily chance: about 20%. Next come Recife (Brazil, about 10%) and Fortaleza (Brazil, about 10%).
GBIF citizen-science records
It is estimated from how often the Brown Vinesnake is recorded against all the reptiles logged in João Pessoa (6 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.
