Red panda at Calgary Zoo dies after 'extremely' long life

A red panda at the Calgary Zoo has died after living more than 18 years nearly double thetypical life expectancy for such an animal in human care.

Nicknamed Dusk, the male arrived in Calgary in 2013 from Winnipeg when hewas nine years old.

"During his lifetime, Dusk was a 'conservation superstar,'having successfully sired six cubs as part of the Red Panda Species Survival Plan (SSP), including our three-year-old female, Udaya," the CalgaryZoo said in a statement.

The red panda spent less time in public view recently as he needed specialized care and attention.

The animal spent much of its time in a private habitat where itcould move at itsown pace and "enjoy some quiet time away from the more rambunctious young ones in our pack."

The red panda was euthanized after a recentveterinary exam revealed a diagnosisthat includedprogressive heart disease coupled with advanced kidney disease.

At 18 years old, Duskwas "extremely geriatric" for itsspecies, zoo officials said.

The median life expectancy for red pandas under human care is 10 years, the zoo said, attributingDusk's "exceptionally advanced age"to the care it received over its lifetime.

The zoo said the red panda'slegacy lives on through its offspring, including a female that's given birth to two "grandcubs" namedSundariand Ravi.
