The Pride of Chicago.
Chicago, February 1, 2012. Sad news from Chicago's Lincoln Park Zoo, who just announced that the animal care staff made the difficult decision to euthanize Adelor, a geriatric male African lion, due to progressively deteriorating health and quality of life. Adelor, who was 18 years old, was a favorite of many of the visitors to Lincoln Park Zoo and will be sorely missed. He had lived at the zoo since 1995. Adelor was the proud father of five cubs.
Adelor could often be found soaking up the sun at his favorite spot, pictured above, on the top of the large boulders of the exhibit.
Zoological manager, Mark Kamhout, fondly remembers “Guests of all ages flocking to the lion exhibit when Adelor began roaring as he announced his territory several times a day. He was a wonderful leader of the pride and was very protective and affectionate of the females under his care” said Kamhout.
The median life expectancy for lions (assuming the individual survives the first year of life, a particularly risky time for most mammals) is approximately 14 years. The maximum longevity recorded is 26 years.
