The Eastern Garter Snake (Thamnophis sirtalis sirtalis) is a medium-sized snake that is indigenous to North America.
Taxonomy and evolution
The scientific name "Thamnophis sirtalis sirtalis" is a combination of Greek and New Latin that means "bush snakes that looks like a garter strap". The genus name "Thamnophis" is derived from the Greek "thamnos" (bush) and "ophio" (snake) and the New Latin "siratalis" (like a garter). The species name siratalis is a reference to the snake's pattern resembling a striped garter strap.
Identification and physical description
Distribution and habitat
The Eastern Garter Snake has a wide range across eastern North America, going as far north as southern Ontario and Quebec to the Gulf of Mexico in the south, along the eastern shores of America to the Mississippi River. In New England, the snake is described as the "most widespread and ubiquitous" serpent, from wilderness to urban environments and from sea level to high elevations.
The Eastern Garter Snake will live in a variety of environments, with a preference for grassy or shrubby fields, including abandoned farmland, outbuildings and trash dumps. In particular the snake likes to inhabit stone walls that separate the forest from fields. It is also found along moist habitats such as lakes, rivers, streams, swamps, bogs, ponds, drainage ditches, quarries. Snakes are present in urban environments in habitats that include "city parks, cemeteries and suburban yards and gardens". Eastern Garter Snakes like to conceal themselves under logs, stones and other debris that allow them to bask in the sunlight and quickly seek refuge from predators. Krulikowski notes that "[o]ld poultry farms with discarded sheet-metal incubation trays provide warm, moist hiding places."
Behavior and diet
They mostly eat toads, frogs, and worms, but they will eat almost anything that they can overpower.
