In loving memory of Mochica. At 31, he was one of the oldest and best-loved Humboldt penguins on the planet. The Oregon Zoo bid a sad farewell over the weekend to Mochica, elder statesman of the Humboldt penguin colony and a distinguished seabird ambassador for more than three decades. At 31 years old, he was one of the oldest — and best loved — penguins on the planet. “Mochica was the oldest male of his species in any North American zoo or aquarium, maybe the whole world,” said Travis Koons, who oversees the zoo’s bird populations. “His remarkable longevity says a lot about both his zest for life and the quality of care he received over the years.” Mochica hatched July 6, 1990, at the Oregon Zoo and was hand-reared, a standard practice at the time. But Mo, as he was known for short, grew up different from the other chicks. More than any penguin in the zoo’s large Humboldt colony, he enjoyed spending time with people, often choosing keepers’ quarters over the company of his fellow birds in the Penguinarium.
