California grizzly bear


The California grizzly bear, also known as the California brown bear, California golden bear, or chaparral bear, is an extinct population of the brown bear, generally known as the grizzly bear. "Grizzly" could have meant "grizzled" that is, with golden and grey tips of the hair or "fear-inspiring". Nonetheless, after careful study, naturalist George Ord formally classified it in 1815 – not for its hair, but for its character – as Ursus horribilis. Genetically, North American brown bears are closely related; in size and coloring, the California grizzly bear was much like the Kodiak bear of the southern coast of Alaska. The grizzly became a symbol of the Bear Flag Republic, a moniker that was attached to the short-lived attempt by a group of U.S. settlers to break away from Mexico in 1846. Later, this rebel flag became the basis for the state flag of California.

Taxonomy and evolution

A 1953 researcher stated, "The specific status of North American brown bears is one of the most complex problems of mammalian taxonomy. The difficulty stems directly from the work of Merriam, who concluded that there are 86 forms of grizzlies in North America."
North American brown bears were taxonomically grouped as a species apart from other bear species, until DNA testing revealed that they should properly be grouped in the same species as the other brown bears. Grizzlies living in California had been classified by Merriam into many subspecies. Over time, these were all synonymized into a single subspecies, Ursus arctos californicus. A study based on mitochondrial DNA suggests that the only genetically anomalous grouping of grizzly bears is the ABC Islands bear, implying that previous grizzly bear subspecies designations are unwarranted. However, a formal taxonomic synonymy was not performed, and mitochondrial introgression is known to be an issue in brown bears. Pending further taxonomic resolution, the subspecies is provisionally accepted as separate.
A recent genomic study recovered the California grizzly within a clade of grizzly bears present in the contiguous United States. The grizzly bear population present in Yellowstone National Park was identified as most closely related to the California grizzly, and that the California population diverged approximately 10,000 years ago. The oldest fossil remains of grizzly bears in California were recovered from the La Brea tar pits. This fossil specimen, weighing ~455 kilograms, is dated to the Greenlandian stage, over 7,500 years ago.

Appearance

The California grizzly was historically considered an enormous bear. Father Pedro Font, an early missionary, described the local grizzly bears, writing, "He was horrible, fierce, large, and fat." In the 1800s, multiple newspaper accounts mentioned bears weighing well over ; the hind foot of one particular adult male grizzly was measured at long by wide, and claws were often wide by long. Measurements of museum specimens, however, demonstrate that this bear was no larger than those present in the rest of North America, with average body size estimates ranging from to depending on methodology.
The fur of the California grizzly bear has been described as golden brown, leading to the occasional name "California golden bear". The captive individual "Monarch" had a dark brown, almost black, pelt.

Diet and behavior

The diet of the California grizzly bear was diverse, ranging from plant sources like grasses, seeds, berries, and acorns, to animal sources such as elk, deer, salmon, steelhead, and carrion. Isotopic study indicates that the majority of the diet consisted of plant matter, as with other grizzly bear populations. Anecdotal reports from Spanish explorers reported California grizzly bears scavenging on beached whale carcasses. After the introduction of European livestock, California grizzly bears increasingly incorporated cattle into their diets. California grizzly bears were primarily solitary, except for mothers with cubs, but foraging groups of up to 40 have been reported.

Distribution and habitat

Prior to Spanish settlement in the second half of the 1700s, it is estimated that 10,000 grizzly bears inhabited what is modern-day California. It is thought that the bears lived across almost the entirety of the state, save its most southeastern and northeastern corners. Probably the southernmost records for this subspecies are from the Sierra de Juárez, during the 18th century. The bear was most abundant in chaparral, oak woodland, and hardwood forests.

Relationship with humans

European contact

The first documented sighting of a grizzly bear in California occurred in 1603 when a Spanish explorer near Monterey described how bears came down to feed on a whale carcass stranded on the beach. However, his reports were not widely circulated, so the existence of grizzlies in California was not well-known to Europeans until the eighteenth century.
Western Europeans' first well-circulated encounters with California grizzly bears are found in diaries kept by several members of the 1769 Portola expedition, the first European land exploration of what is now the state of California. Several place names that include the Spanish word for bear trace their origins back to that first overland expedition. As the settled frontier of New Spain was extended northward, settlers began to populate California and establish large cattle herds as the main industry. The ranchers' livestock were easy prey for the largely herbivorous-omnivorous grizzly bears found across the state. In turn, grizzly populations increased around human settlements. By eating their livelihood, and scaring them, the grizzlies became enemies of the rancheros. Vaqueros hunted the grizzlies, often roping and capturing them alive to be pitted against other animals in public battles.
In 1866, a grizzly bear described as weighing as much as was killed in what is present-day Valley Center, California, in the north-central area of San Diego County. The incident was recalled in 1932 by Catherine E. Lovett Smith, who witnessed the bear's killing on her family's ranch when she was just six years old. If its measurements are accurate, this particular bear was the biggest bear ever found in California and one of the largest specimens of any bear species ever recorded. Her telling of that bear is part of the oral history of "Bear Valley", the original name for Valley Center. The bear was prominent in the Big Sur region of the central California coast. Frank Post, born in 1859 on the Soberanes Ranch in Big Sur, remembered when his family lived at Soberanes Creek, during the American Civil War – recalling the "Great Sur Bears". Inhabiting most of the state, both inland and along the coast, it is likely the California grizzly's southernmost range in the state overlapped with that of the now-extinct Mexican grizzly bear, as well.

Extinction

In the late 1700s, Spanish ranchers placed a poisoned "bait ball" made of suet or swine entrails filled with a lethal dose of strychnine which they hung from the branches of a tree within reach of the bear but out of reach of dogs and children. Mexican settlers captured bears for bear and bull fights and they also sold their skins for 6 to 10 pesos to trading ships. Bear Trap Canyon near Bixby Creek was one of their favorite sites for trapping grizzly bears along the central California coast. These bears were even turned into furniture, such as a chair gifted to President Andrew Johnson in 1865.
Bear-baiting events flourished as popular spectacles in 19th century California. Bloody fights that pitted bears against bulls often inspired betting as to whether the bear or the bull would win. One persistently popular, but false phrase origin story related to these fights stems from famous 19th-century newspaperman Horace Greeley. While visiting California, Greeley allegedly witnessed such a fight, and supposedly gave the modern stock market its "bear" and "bull" nicknames based on the fighting styles of the two animals: the bear swipes downward while the bull hooks upward. In truth, the phrase's origins predate Greeley's 1859 journey to California by at least 100 years, but the myth of the California connection persists.
The Monterey County Herald noted on July 4, 1874:
In the early to mid 19th century, livestock from the ranchos of California provided an abundant food source for the bears, allowing the grizzly population to expand rapidly. However, the cattle population was greatly diminished following extreme drought and flooding in the 1860s and 1870s, leading to a reduction in the number of grizzlies. This coincided with an increased interest in bear hunting, both for sport and commercial purposes. Grizzly bear meat became a mainstay on restaurant menus in the San Gabriel area; according to Mike Davis, “The paws from adult bears and the flesh from young cubs were deemed particular delicacies.”
European settlers paid bounties on the bears who regularly preyed on livestock until the early 20th century. Absolom Beasley hunted grizzly bears throughout the Santa Lucia Mountains and claimed to have killed 139 bears in his lifetime. Noted California mountain man Seth Kinman claimed to have shot over 800 grizzly bears in a 20-year period in the areas surrounding present day Humboldt County. One prospector in Southern California, William F. Holcomb, was particularly well known for hunting grizzly bears in what is now San Bernardino County.
During September 1897, in the mountains between Inwood and Mt. Lassen, Shasta County, 21-year-old Elias Weigart and his dog encountered a huge California grizzly whose front track measured and the rear,. The bear died after Weigart emptied his Winchester 38-55 into the beast at close range.
In 1920, the Shuteye Peak area of Madera County was home to one of the last California grizzlies, nicknamed 'Two Toes,' who lost part of his front foot in a trap and evaded hunters for years.
The last hunted California grizzly bear was shot in Tulare County, California, in August 1922, although no body, skeleton or pelt was ever produced. Less than 75 years after the discovery of gold in 1848, almost every grizzly bear in California had been tracked down and killed. In 1924, what was thought to be a grizzly was spotted in Sequoia National Park for the last time and thereafter, grizzlies were never seen again in California.
