They are very good climbers capable of ascending even vertical, branchless tree trunks. It may occur in southern Poland although this requires confirmation. There are also fossils showing that they had UK residency during earlier interglacial periods but were driven south afterwards with subsequent glacials ; these repeated climate-caused contractions and extensions of range in Europe appear to have occurred multiple times over the Pleistocene. Juveniles can easily be confused with juvenile grass snakes Natrix natrix and barred grass snakes Natrix helvetica , because juvenile Aesculapian snakes also have a yellow collar on the neck that may persist for some time in younger adults. Juveniles may be eaten by smooth snakes and other reptilivorous snakes. With up to 2 meters in length, it counts among the largest European snakes, though not as massive as the Four-lined Snake or the Montpellier Snake.

They also eat birds as well as bird eggs and nestlings. Other distinctions, as in many snakes, include in males a relatively longer tail to total body length and a wider tail base.
