The brown water snake (Nerodia taxispilota) is a large species of nonvenomous natricine snake endemic to the southeastern United States. This snake is often one of the most abundant species of snakes found in rivers and streams of the southeastern United States, yet many aspects of its natural history are poorly known. Due to abundance and distribution throughout its biological range, this species could be used to investigate anthropogenic impacts on aquatic ecosystems by studying their movements.
Lycodonomorphus rufulus is sometimes also called the brown water snake, but L. rufulus is found in South Africa. Its common names include brown water snake, water-pilot, aspic, false moccasin, great water snake, pied water snake, southern water snake, and water rattle. Nerodia taxispilota is found in lower coastal regions from southeastern Virginia, through North Carolina, South Carolina, and Georgia, to northern and western Florida (Gulf Coast), then west through Alabama, and Mississippi, to Louisiana, normally from sea level to 500 ft. (150 m) elevation.
The brown water snake is very heavy-bodied, and its neck is distinctly narrower... Wikipedia →

With luck
About 10% of wildlife watchers report a Brown Watersnake sighting in Orlando on a given day, based on 28 verified sightings from GBIF citizen-science data. It is the 16th most-seen of the 32 reptiles we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
May–August, October and December–February
In those months about 10% of wildlife watchers report a Brown Watersnake in Orlando on a given day, against under 5% in March–April, September and November, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Brown Watersnake sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is seen both by day and at night.
Among the best
Of the 2 cities where we can rate Brown Watersnake sightings, Orlando ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Miami (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Brown Watersnake is recorded against all the reptiles logged in Orlando (28 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.
