Thamnophis saurita, also known as the eastern ribbon snake, common ribbon snake, or simply ribbon snake, is a common species of garter snake native to Eastern North America. It is a non-venomous species of snake in the subfamily Natricinae of the family Colubridae. The ribbon snake averages 16 to 35 inches (41 to 89 cm) in total length (including tail). It is dark brown with bright yellow stripes. The ribbon snake is not sexually dimorphic; however, females are normally thicker than their male counterparts.
The ribbon snake can be found in wet climates such as lakes, streams, ponds and marshes. The ribbon snake is active from April to October and hibernates during the winter months. Maturity is reached around 3 years of age.

With luck
About 10% of wildlife watchers report a Ribbon Snake sighting in Washington on a given day, based on 246 verified sightings from GBIF citizen-science data. It is the 10th most-seen of the 25 reptiles we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
March to November
In those months about 10% of wildlife watchers report a Ribbon Snake in Washington on a given day, against under 5% in December to February, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Ribbon Snake sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

Of the 3 cities where we can rate Ribbon Snake sightings, Washington has the highest daily chance: about 10%. Next come Orlando (United States, under 5%) and Miami (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Ribbon Snake is recorded against all the reptiles logged in Washington (246 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.
