Wildcat

This subspecies is widely distributed on the desert slope of the range,

and was recorded down to the lower edge of the juniper belt. Tracks were

observed on many occasions in yellow pine forest, but wildcats seemed to

be commonest in the brushy parts of the pinyon-juniper association. Two

were trapped in small draws lined with pinyons and scrub oak, and two

at the base of rocky pinyon-covered slopes. Only occasionally were

tracks noted in the lower part of the juniper belt. Bobcats are most

numerous where woodrats also reach peak abundance, suggesting that

woodrats are a major food.

The four specimens from the desert slope, although exhibiting a wide

range of variation, are all representatives of the desert race

_baileyi_. A yearling male from near the head of Grandview Canyon, at

5200 feet elevation, has the profuse black spotting of the subspecies

_californicus_, but the general pallor dorsally is characteristic of the

desert subspecies. An adult female, from 4700 feet elevation in Graham

Canyon, shows the double mid-dorsal black line and the distinct black

markings around the face characteristic of _californicus_, but is

otherwise pale with reduced black patterns on the backs of the ears. The

other two specimens, an adult male and a yearling female, are typical

examples of _baileyi_, pale, and with reduced black markings. None of

the specimens of bobcats from the coastal slope of the mountains showed

characters approaching those of _baileyi_. It seems, therefore, that

these two subspecies intergrade on the interior slope of the range.

A yearling male weighed 12 pounds, and a yearling female weighed 10.5

pounds. An old male weighed 19.6 pounds, and an adult female weighed

15.1 pounds.

Remains of deer were in two of the bobcat stomachs, and one of these

stomachs also contained jack rabbit remains. Approximately a dozen

nematodes (stomach worms) were in the stomach of one of the larger male

specimens.
