The California mountain kingsnake is a nonvenomous colubrid snake native to North America. It has a banded pattern that consists of red, black, and white crossbands. The bands are always arranged in the same order with each red crossband being surrounded by two black crossbands, forming what is called a triad. Each triad is separated from the next triad by a white crossband, or in some examples by a cream or yellow crossband. Some individuals may have reduced amounts of red pigment, and rare individuals may have virtually no red bands at all.

Distribution

California mountain kingsnakes are found in western North America, in the Western United States and northwest Mexico. They range from extreme southern Washington state through Oregon and California, to northern Baja California. These snakes live mostly in the mountains where they inhabit coniferous forests, oak woodlands, and shrubland.

Habits and Lifestyle

California mountain kingsnakes are secretive creatures that lead a solitary life and spend most of the time in their underground burrows or hide under rocks, logs, bark, and other objects. They are very good climbers and may sometimes climb in trees. During cold months of the year, California mountain kingsnakes hibernate in burrows under the ground or in deep rock crevices. They are generally diurnal and hunt by day using their sight and smell to find prey. Being nonvenomous, California mountain kingsnakes rely on their bright coloration when they feel threatened; they are similar in appearance to the very venomous Coral snake, and thus bright coloration warns and confuses potential predators.
