Aesculapian snake

Zamenis longissimus

Smooth bronze scales can travel far above the forest floor.

The Aesculapian snake is a slender climber associated with wooded habitats and their edges. Young snakes can carry a pale collar that is much less obvious in the more uniform adult appearance.[1]

Scales assist climbing

The belly scales angle sharply where the underside meets the flanks. Together with the slender body, this assists climbing on trees and structures. Foraging can therefore occur above ground as well as below the canopy.[1]

A patchwork of temperature choices

Forest clearings, edges, walls and vegetation can provide shelter and basking places. The snake uses this structural variety to regulate exposure rather than simply occupying the hottest available spot.[1]

Food changes with growth

Small mammals are important adult food, with birds, eggs and nestlings also taken. Juveniles more often use smaller animals such as lizards and arthropods. Constriction helps handle much of the larger prey.[1]

A COMMON MIX-UP

Does a pale collar identify every age as a grass snake?

No. Young Aesculapian snakes can have a collar too. Age-related appearance must be considered alongside other features.[1]

TRY A LITTLE REASONING

Why include vertical habitat in a survey?

Reveal the explanation

This climber may forage or rest above the ground, so a ground-only view does not cover the places it uses.[1]
