Oldest female African Penguin on record dies at Pueblo Zoo

Tess had lived at the Pueblo Zoo since 1999.

Tess was the oldest known living African Penguin in captivity and the oldest female on record. The average life expectancy of African Penguins is 15 to 20 years.

“She was truly a special animal.” says her primary keeper Melanie Pococke. “Though she was slowing down in her advanced age, she lovedher early morning swims and being given a little special attention at feeding times.” She is survived by her mate, Mongo.

Tess recently went through advanced cancer treatment at Colorado State University Veterinary School.

The zoo is awaiting test results to determine exact cause of death.
