All 4 feet are visible, arranged in a compact, trapezoidal pattern. Tracks were only a few feet away from wire fence, facing directly away from wire and post fence. We thought initially cat jumped fence and landed compactly here. But the toes of the front tracks are not splayed, so perhaps it was merely crouched here. Nothing at the site indicated it had to have come from the other side of the fence. We failed to check fence top for hairs.

One of two mandibles found amongst raven feeding debris near Mail Point, San Clemente Island. Missing posterior processes, so partial mandible length is ~20 mm. There is not a steep drop from the anterior end of the cheek to the diastema, as seen in Norway Rat. Black rats are well-documented on the island: Spatial Ecology of Invasive Black Rats ( Rattus rattus ) On San Clemente Island, California
