The long-nosed snake (Rhinocheilus lecontei) is a species of nonvenomous snake in the family Colubridae. The species is endemic to North America. It has two recognized subspecies. The other species in the genus were previously considered subspecies.
The specific name, lecontei, commemorates American entomologist John Lawrence Le Conte (1825–1883). The long-nosed snake is distinguished by a long, slightly upturned snout, which is the origin of its common name. It is tricolor, vaguely resembling a coral snake, with black and red saddling on a yellow or cream-colored background. Cream-colored spots within the black saddles are a distinct characteristic of the long-nosed snake. It differs from all other harmless snakes in the United States by having undivided subcaudal scales. The total length (including tail) of adults is usually 22–32 in (56–81 cm), but the maximum record total length is 41 in (100 cm).
R. lecontei is a shy, nocturnal burrowing snake. It spends most of its time buried underground. The long-nosed snake feeds on lizards, amphibians, and sometimes smaller snakes and infrequently rodents. R. lecontei... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Long-nosed Snake is recorded against all the reptiles logged in Big Bend National Park (51 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.
