Philodryas chamissonis, commonly known as the Chilean green racer and the Chilean long-tailed snake, is a species of moderately venomous opisthoglyphous (rear-fanged) snake in the family Colubridae. The species is endemic to Chile.
The specific name, chamissonis, is in honor of German botanist and poet Adelbert von Chamisso. P. chamissonis has a large distribution in Chile, from Paposo to Valdivia. Usually, P. chamissonis is gray, with black and white longitudinal stripes on the body. It is a medium-sized snake, which usually reaches 1.4 m (4.6 ft) in total length (including tail).
The length of the tail is 25–28.5 % of the total length. There are 8 upper labials, the 4th and 5th entering the eye. The smooth dorsal scales are arranged in 19 rows at midbody. Ventrals 179–225; anal plate divided; subcaudals 100–122.
P. chamissonis lives in a large variety of habitats, at altitudes from sea level to 2,300 m (7,500 ft). The diet of P. chamissonis is mainly composed of little rodents, birds, amphibians, and other smaller reptiles. For example, it especially preys upon lizards of the genus Liolaemus.

With luck
About 10% of wildlife watchers report a Chilean Green Racer sighting in Santiago on a given day, based on 27 verified sightings from GBIF citizen-science data. It is the 5th most-seen of the 8 reptiles we can rate there. Over three days the chance rises to about 40%, and over a week to about 60%, if each day is a fresh chance.
March–April, June and October–November
In those months about 20% of wildlife watchers report a Chilean Green Racer in Santiago on a given day, against under 5% in January and September, the lowest months.
Only Santiago, in our data
Santiago is the only city on Wallace's Line with enough records to rate Chilean Green Racer sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Chilean Green Racer is recorded against all the reptiles logged in Santiago (27 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.
