March of the penguins 2: Back to the penguinarium

The zoo's Humboldt penguins return home after a brief stay in the polar bear habitat

After a monthlong stay in the polar bear habitat while repairs were made to their penguinarium, the zoo's 25 Humboldt penguins are marching home. They completed the 100-yard migration Thursday morning with the help of a team of keepers, and guests can visit them in their new and improved habitat starting this weekend.

"The penguins did really well in the polar bear habitat," said Travis Koons, who oversees the zoo's bird population. "But it's always nice to come home."

It's especially nice to come home to a clean house. The penguin colony will enjoy some upgrades to their habitat, including a newly refreshed attic area for the Inca terns who share their space. Upon returning home, the birds eagerly waddled in and took a quick look around before splashing into their 25,000-gallon pool.

In 2012, the zoo completed an upgrade of the penguinarium's water-filtration system, one of many improvements funded by the community-supported 2008 zoo bond measure aimed at protecting animal health and safety while conserving and recycling water. The upgrade saves millions of gallons each year.

Humboldt penguins, which live along the South American coastline off of Peru and Chile, are classified as "vulnerable" by the International Union for Conservation of Nature, and in 2010 were granted protection under the U.S. Endangered Species Act. Of the world's 17 penguin species, Humboldts are among the most at risk, threatened by overfishing of their prey species, entanglement in fishing nets, and breeding disruption due to commercial removal of the guano deposits where the penguins lay their eggs. Their population is estimated at 12,000 breeding pairs.

Through its Future for Wildlife program, the Oregon Zoo has supported Peru-based conservation organization ACOREMA's work to protect the vulnerable Humboldt penguin. ACOREMA monitors penguin mortality and works closely with San Andrés fishermen to mitigate the practice of hunting penguins for food. The group also trains volunteer rangers, reaching out to 3,000 students, teachers and Pisco-area residents a year to raise awareness about penguin conservation.

The Oregon Zoo is a service of Metro and is dedicated to its mission of inspiring the community to create a better future for wildlife. Committed to conservation, the zoo is currently working to save endangered California condors, Columbia Basin pygmy rabbits, Oregon silverspot and Taylor’s checkerspot butterflies, Western pond turtles and Oregon spotted frogs. Other projects include studies on black rhinos, Asian elephants, polar bears and bats.
The zoo relies in part on community support through donations to the Oregon Zoo Foundation to undertake these and many other animal welfare, education and sustainability programs. The zoo is located five minutes from downtown Portland, just off Highway 26 at exit 72. The zoo is also accessible by MAX light rail line. Visitors who travel to the zoo via MAX receive $1.50 off zoo admission. Find fare and route information online or by calling TriMet Customer Service at 503-238-RIDE (7433).
General zoo admission is $10.50 (ages 12-64), $9 for seniors (65 and up), $7.50 for children (ages 3-11) and free for those 2 and younger; 25 cents of the admission price helps fund regional conservation projects through the zoo’s Future for Wildlife program. A parking fee of $4 per car is also required. Additional information is available by calling 503-226-1561.
