Common names: western bush viper, West African leaf viper, more. Atheris chlorechis is a viper species found only in the forests of West Africa. No subspecies are currently recognized. It is the type species of its genus. Like all other vipers, it is a venomous species.
Atheris chlorechis venom can lead to major systemic envenoming, shock, blood loss due to coagulopathy, and renal failure. There is no antivenom. Adults average 50 cm (20 inches) in total length (body + tail), with a maximum total length of 70 cm (28 in). The tail is relatively long. The body is relatively slender, with 25–36 midbody rows of dorsal scales. These are heavily keeled, with the keels ending in a swelling at the end of each scale.
Adults have a uniform light green ground color, overlaid with a series of faint yellow, roughly paired spots running dorsally along the length of the body and about 2.5 cm (about 1 in) apart. The belly is pale green in color. Newborns are tan-brown in color, but this changes to a yellow-green hue with irregular dark spots within 24 hours. This second color phase has been described as the reverse of that of the adults and is only seen in individuals less than 25... Wikipedia →

No species of the same family or order lives in Taï National Park, so these are its closest relatives here: other reptiles.
Very likely
About 70% of wildlife watchers report a Green Bush Viper sighting in Taï National Park on a given day, based on 18 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the most-seen of the 9 reptiles we can rate there. Over three days the chance rises to over 90%, if each day is a fresh chance.
June
In that month about 80% of wildlife watchers report a Green Bush Viper in Taï National Park on a given day, against about 10% in March, the lowest month. That is one of Taï National Park's wettest months, with about 280 mm of rain against 40 mm in December. October to February have too few records to rate.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Green Bush Viper sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Taï National Park, in our data
Taï National Park is the only park on Wallace's Line with enough records to rate Green Bush Viper sightings: about 70% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Green Bush Viper is recorded against all the reptiles logged in Taï National Park (18 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.
