SEATTLE - Woodland Park Zoo veterinarians humanely euthanized a 7-year-old female Humboldt penguin over the weekend, due to complications associated with egg yolk peritonitis. “The penguin retained an egg which caused a rupture of the reproductive tract and resulted in the release of egg material into the abdomen. This led to a life-threatening infection,” explained zoo Associate Veterinarian Dr. Kelly Helmick. “We attempted a surgical repair of the damage, but the changes were too severe and humane euthanasia was performed.” Humboldt penguins may live through their 20s at zoos. Nine penguins remain in the zoo’s colony.

People do not usually think of penguins as a desert species. Unlike their ice and snow-dwelling Antarctic cousins, Humboldt penguins inhabit hot, dry coastlines in Peru and Chile. They live on rocky mainland shores, especially near cliffs, or on coastal islands. Humboldt penguins have a body made to swim. Using their strong wings, they "fly" underwater, usually just below the surface, at speeds of up to 20 miles per hour. They steer with their feet and tail.

Woodland Park Zoo participates in the Humboldt penguin Species Survival Plan (SSP), a cooperative breeding program to help ensure genetic diversity and demographic stability in North American zoos. The zoo participates in 35 SSPs, which are administered by the American Zoo and Aquarium Association (AZA). Additionally, SSPs involve a variety of other collaborative conservation activities such as research, public education, reintroduction and field projects. AZA is a nonprofit organization dedicated to the advancement of zoos and aquariums in the areas of conservation, education, science, and recreation, with more than 205 zoos and aquariums as members.

Accredited by the American Zoo and Aquarium Association, award-winning Woodland Park Zoo is famed for pioneering naturalistic exhibits and setting a standard for zoos all over the world. With conservation, education and excellent animal care at the core of the zoo’s mission, the zoo is helping to save endangered species in Washington state and around the world including tree kangaroos, snow leopards, red-crowned cranes, African wild dogs, western pond turtles and Oregon silverspot butterflies. By inspiring visitors and others to care and act, Woodland Park Zoo is making a difference in our planet’s future.
