Snake tracks provide fascinating clues about the presence and movement of these reptiles. Observing tracks requires a keen eye and knowledge of how snakes interact with their environment.
Decoding Snake Track Patterns
Snakes employ several methods of movement, each leaving a unique signature on the ground. The most recognized is lateral undulation, often called serpentine motion, where the snake propels itself forward by pushing against irregularities in the surface, creating a continuous, wavy, S-shaped track. This pattern is common in various terrains, from soft soil to water.
Another distinct pattern comes from sidewinding, a specialized movement used on loose or slippery surfaces like sand. Here, the snake lifts sections of its body, creating a series of disconnected, J-shaped or diagonal parallel lines, with the body rolling from head to tail. This method allows for efficient travel across unstable ground.
Rectilinear locomotion involves the snake moving in a straight line, utilizing its belly scales to grip and pull the body forward. This creates a straight, sometimes segmented, track and is seen in larger, heavier-bodied snakes. Concertina movement is characterized by the snake bunching its body into bends and then extending forward from those coils. This method is used in confined spaces, like tunnels or when climbing, and leaves a series of accordion-like impressions, though these tracks are less commonly observed in open environments. A less frequent movement is slide-pushing, where a startled snake on a smooth surface makes forceful, wide undulations, resulting in broad, sliding tracks.
Prime Locations for Discovery
Identifying ideal spots for finding snake tracks improves discovery chances. Sandy areas and loose soil are excellent substrates, as they clearly show the patterns of locomotion. Tracks are also often found near water sources like creeks, ponds, or lakes, where snakes may go to hunt, drink, or regulate their body temperature. Rocky outcrops and areas with fallen logs or dense vegetation offer cover and warmth, making them likely places for snake activity.
Searching during cooler parts of the day, such as early morning or dusk, when temperatures are between 68 and 80 degrees Fahrenheit, is productive as snakes are most active within this range. This timing often yields the freshest tracks.
Telling Snake Tracks Apart
Distinguishing snake tracks from other ground disturbances is important for accurate identification. A true snake track will show a continuous, limbless pattern, reflecting its movement across the surface. This contrasts with trails left by lizards, which often include intermittent foot or tail drag marks, or rodent trails that feature distinct paw prints.
Marks from dragging branches or human-made disturbances, such as those from rakes or hoses, can mimic snake patterns but lack the consistent, fluid characteristics of a snake’s movement. Snake tracks do not show distinct impressions from individual scales, except in very fine substrates with fresh sidewinder tracks. While identifying the snake species from tracks alone is challenging, the track’s width and the specific locomotion pattern can provide clues about the size and type of snake that passed through.
Safe Track Exploration
Observing snake tracks in their natural setting requires safety measures. Always maintain a respectful distance from any snake habitat, generally at least six feet, to avoid disturbing the animal or provoking a defensive reaction. Never attempt to handle a snake, even if it appears to be dead, as reflexes can still cause a bite.
Being aware of your surroundings means watching where you place your feet and hands, especially when stepping over logs or reaching into obscured areas. Wearing sturdy boots and long pants can offer some protection against accidental encounters. Observation from a safe distance is the goal, allowing both you and the wildlife to remain undisturbed.
