Grizzly Bear at Cleveland Zoo. See photos of Warren (the grizzly bear) and his new "bride" on Flickr. Lester, the older grizzly bear was euthanized at Cleveland Metroparks Zoo in October 2010. The 760-pound male grizzly was captive-born and came to Cleveland in 1975 from the Milwaukee County Zoological Gardens at age 11 months. The 35-year-old grizzly, known as “Lester,” suffered from age-related ailments such as arthritis, but the immediate cause of his rapid decline in health is unknown.

Grizzly bears (Ursus arctos horribilis) in the wild have an average lifespan of 20-30 years, and typically live a few years longer in captivity.

Lester shared his exhibit in Northern Trek with the Zoo’s other grizzly, his offspring, Warren, age 26.
