The harmless and generally docile Eastern Ratsnake (Pantherophis alleghaniensis) is one of our most common and frequently encountered snakes. Maryland's largest snake species, it may reach an impressive size. Adults average 4.5 to 5.5 ft. in length (the rangewide record is 101 inches)(Conant & Collins, 1998). Eastern Ratsnakes may be found in virtually any non-urbanized habitat, including hardwood forests and edge habitats, agricultural areas, uplands and wetlands, and most other wooded habitats, provided there is a consistent rodent population. Ratsnakes are able climbers, and individuals may frequently be seen ascending tree in search of bird nests, or natural cavities to rest in (Tennant, 2003; Maryland DNR site). Eastern Ratsnake is found commonly throughout the state.
The Eastern Ratsnake is an excellent climber that preys upon small mammals, birds, and bird eggs. It is perhaps the most likely snake species to raid a nest box without a protective "baffle."
