Arizona Gray Squirrel Sciurus arizonensis

Track Foreprints round, 1" (25–27 mm) long; hindprints more triangular, 2 1/4" (56–58 mm) long. When bounding, paired hindprints are slightly ahead of paired foreprints; sometimes foreprints are between rear parts of hindprints, often directly behind them, leaving tracks like exclamation points (!!); bounding stride ranges from a few inches to over 3' (900 mm)

Sign Remnants of gnawed acorns and pine seeds. Nest: Placed in a hollow tree or a loose, ball-shaped nest of leaves in high tree crotches or limbs
