Quick Answer
Identifying different age classes of mountain lions by tracks requires knowledge of their distinctive characteristics, such as paw size, shape, and gait impressions. Mountain lion tracks typically exhibit a larger paw pad in kittens and smaller adults, while larger adults often display a more worn and oval-shaped track. Observing the track's width and impression depth can also help determine age class.
Mountain Lion Track Characteristics
To identify age classes, look for the following characteristics: kittens (0-1 year) have relatively large paw pads (typically 4-5 inches in diameter) with a more rounded shape, while smaller adults (1-2 years) display smaller paw pads (3-4 inches in diameter) with a more oval shape. Larger adults (2-3 years and older) often have worn and irregularly shaped paw pads (4-6 inches in diameter). Pay close attention to the track’s width and impression depth, as these can vary significantly between age classes.
Gait and Track Spacing
Gait and track spacing are also essential factors to consider when identifying age classes. Kittens tend to have a more irregular gait with wider track spacing (typically 12-18 inches apart), while smaller adults exhibit a more consistent gait with narrower track spacing (8-12 inches apart). Larger adults display a more streamlined gait with even closer track spacing (6-8 inches apart). Note that these values can vary depending on the individual animal and terrain.
