The grizzly bear ("Ursus arctos" ssp.)
 is a large subspecies of brown bear inhabiting North America.
 Scientists generally do not use the name grizzly bear but call it the North American brown bear.
Kiss the Crystal Flake is the sixth studio album by the northern California rock band The Mother Hips.
 The songs "Time We Had" and "Time-Sick Son of a Grizzly Bear" were featured as playable tracks in the music video game "Rock Band".
 "Time-Sick Son of a Grizzly Bear" also includes a reference to the infamous Mexican patriot/bandit Joaquin Murrieta with the lyrics: "Were you out in Monterey/ In Joaquin Murrieta's day/ Adobe huts in the cypress groves/ Is where the rich man now builds his homes".
Grizzly Bear is an American rock band from Brooklyn, New York, formed in 2002.
 The band consists of Edward Droste (vocals, guitar, keyboards, omnichord), Daniel Rossen (vocals, guitar, banjo, keyboards), Chris Taylor (bass, backing vocals, various instruments, producer), and Christopher Bear (drums, backing vocals).
 The band employs traditional and electronic instruments.
 Their sound has been categorized as psychedelic pop, folk rock, and experimental, and is dominated by the use of vocal harmonies.
Operating as a non-profit environmental land trust, The Vital Ground Foundation protects and restores North America’s grizzly bear populations by conserving wildlife habitat.
 Founded in 1990, Vital Ground operates in the belief that the grizzly bear, an umbrella species, is nature’s barometer of a healthy and complete ecosystem, and that conserving grizzly bears and their habitat is key to ensuring diverse and healthy landscapes.
Residual Kid is an American rock band from Austin, Texas formed in 2009.
 The group consists of Deven Ivy (vocals, guitar), Ben Redman (drums), and Max Redman (bass guitar).
 They have released three EPs: "Box" in 2011, which was recorded with an earlier lineup, "Faces", featuring the current lineup, in 2012, and "Salsa" in 2016.
Old Martin was a large grizzly bear given in 1811, when already full-sized, to George III by the Hudson's Bay Company.
 The bear was sent to the Royal Menagerie, housed at the Tower of London.
 Although this was the first grizzly bear in England, the king said he would rather have had been given a new tie or a pair of socks.
 The Royal Menagerie was closed in 1831 or 1832 by the Duke of Wellington, the governor of the Tower.
 The bear and other animals were moved to the new London Zoo in Regent's Park – Old Martin died there in 1838.
Grizzly (also known as Killer Grizzly on television) is a 1976 thriller film directed by William Girdler, about a 15-foot-tall, man-eating grizzly bear that terrorizes a National Forest.
 It stars Christopher George, Andrew Prine and Richard Jaeckel.
 Widely considered a "Jaws" rip-off, "Grizzly" used many of the same plot devices as its shark predecessor, which had been a huge box-office success during the previous year.
 The giant grizzly bear in the film was portrayed by a bear named Teddy, who was 11 feet tall.
Old Ephraim or Ol' Ephraim is a term popularized in the 19th-century American West to refer to grizzly bears.
 As well as describing the archetypal grizzly bear, the name has also been used in frontier folklore to refer to specific bears, most notably Old Ephraim (known as "Old Three Toes" by sheepherders due to a deformity on one foot), a very large grizzly bear that roamed the Cache National Forest in Idaho and Utah from circa 1911 until his death on August 22, 1923.
 He was named after another grizzly bear in California described in a story by P. T. Barnum.
Seekers is a children's novel series written by a team of authors under the pseudonym Erin Hunter, who also wrote the "Warriors" series.
 "Seekers" follows the adventures of four bear cubs: Kallik (a polar bear), Lusa (a black bear), Ujurak (a small grizzly bear who can shape-shift into any animal), and Toklo (also a grizzly bear).
 Led by Ujurak, the four bears search for a place where they can live in peace without human interference and harassment.
 The first book "The Quest Begins" was released on May 27, 2008 and was followed by "Great Bear Lake", "Smoke Mountain", "The Last Wilderness", "Fire in the Sky", and "Spirits in the Stars", released on February 8, 2011.
 The series has been well received, with critics praising the realistic behavior of the characters, the excitement in the novels, and the descriptions of the bears' world.
The discography of Grizzly Bear includes five studio albums, five extended plays and eight singles.
 Grizzly Bear is an American alternative rock band that was formed in 2002 by Ed Droste.
 After the band's first studio album was released, Droste was joined by drummer Christopher Bear, bass guitarist and producer Chris Taylor, and guitarist Daniel Rossen.
