Salvadora bairdi, also known commonly as Baird's patchnose snake and la culebra chata de Baird in Mexican Spanish, is a species of snake in the subfamily Colubrinae of the family Colubridae. The species is native to central Mexico.
The specific name, bairdi, is in honor of American zoologist Spencer Fullerton Baird. S. bairdi is found in the Mexican states of Aguascalientes, southern Chihuahua, Colima, Durango, Guanajuato, Guerrero, Hidalgo, Jalisco, Michoacán, Morelos, Nayarit, Oaxaca, Puebla, Querétaro, Sinaloa, Sonora, and Veracruz.
The preferred natural habitats of S. bairdi are forest and shrubland, at altitudes of 1,200–2,400 m (3,900–7,900 ft), but it has also been found in agricultural areas. In S. bairdi the rostral does not have free edges. The pale vertebral stripe is three dorsal scales wide on the neck, and tapers to one dorsal scale wide on the posterior third of the body.
S. bairdi is terrestrial. S. bairdi preys upon amphibians, small lizards, and small mammals. S. bairdi is oviparous. An adult female may lay one or two clutches per season. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Baird's Patchnose Snake is recorded against all the reptiles logged in Mexico City (45 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.
