What is kaibab squirrels?

Kaibab squirrels (Sciurus kaibabensis) are a subspecies of the North American red squirrel (Tamiasciurus hudsonicus). They are found only in the Kaibab Plateau region of northern Arizona, near the Grand Canyon.

Kaibab squirrels are distinguished from other red squirrels by their larger size, longer ear tufts, and distinctive white tail fringe. They have a reddish-brown fur on their back and sides, with a white underbelly. They are generally about 18-22 cm (7-9 in) in length and weigh 250-300 grams (8-10 oz).

Kaibab squirrels primarily eat seeds, nuts, and pine cones, but they also consume insects, berries, and other vegetation. They have a unique relationship with the ponderosa pine trees in their habitat - these squirrels are the only known animals to eat the seeds of a specific subspecies of ponderosa pine, helping to disperse the tree's seeds and contribute to the expansion of the pine forest.

Due to their limited range and unique ecological role, Kaibab squirrels are considered a conservation priority. They are not currently listed as an endangered species, but their population size is closely monitored and efforts are made to protect their habitat.
