ROYAL OAK, Mich. (AP) — A new penguin habitat that the Detroit Zoo calls the world's largest such facility offers its 80-plus residents new rocks for climbing, waves, snow and better ice conditions, while allowing visitors to come nose-to-beak with the stately birds.
A preview Wednesday showed off the $30 million Polk Penguin Conservation Center, which features an underwater gallery and two acrylic tunnels where visitors can watch four species of penguins swim above, around and below them.
Zoo officials say it's designed to simulate the penguins' native habitat, including optimal air and water temperatures. Zoo CEO Ron Kagan, who made multiple research trips to Antarctica, says the penguins can "do the polar plunge" in the 25-foot-deep aquatic area.
"This is so new, they're still learning this new environment," Kagan said in an interview. "They've never been able to dive this kind of depth. They've never had this kind of opportunity for ice and snow."
Sixty-nine penguins — gentoos, macaronis and rockhoppers — have marched over to their new home, which opens to the public on Monday. Fourteen king penguins will arrive in a bit.
The 33,000-square-foot Polk Center is situated on two acres. In addition to the 326,000-gallon swimming pool, the new inhabitants also have the option of spending time chilling in their spacious above-ground abode that includes expansive windows that allow visitors to see in — and the penguins to see out.
The environment is intended to encourage the same kind of behavior as in the wild, from leaping in and out of the water to nesting and rearing young.
"We've had penguins at the Detroit Zoo for many years, so we know how to feed penguins and keep them healthy," said Scott Carter, the zoo's chief life sciences officer. "What we wanted to make sure we could do here was make sure that we could create an environment in which penguins could really be happy, in which penguins could thrive."
The center's design, inspired by the harsh climate of Antarctica, features an exterior that resembles a towering iceberg with a crevasse and waterfall.
It's "the biggest project that the Detroit Zoo has ever undertaken" Kagan said. A $10 million donation from the Polk Family Fund is the largest gift in the zoo's 88-year history.
The center is free with Detroit Zoo admission, but requires timed-entry passes that are available on a first-come, first-served basis.
