Cut and pasted from the zoo's website:
The new penguin exhibit opens in summer 2009, with plans for a larger colony of up to 20 breeding pairs. The current structure was built in 1947 for seals and sea lions. In keeping with the zoo’s numerous awards for naturalistic exhibitry, the new, 17,000-square-foot exhibit will be a “signature experience” for the marine-savvy Pacific Northwest. It is being designed to be environmentally friendly for penguins and for people, with an innovative filtration system to recycle virtually all of the water. Shoreline cliffs, crashing waves, rocky tide pools, and nesting burrows will cater to the birds’ natural coastal behavior and highly social demeanor. Guests will enjoy nearly nose-to-beak viewing of the black and white torpedoes “flying” underwater at speeds of up to 17 mph, porpoising through the air and raising young chicks. A core theme is the plight of Humboldt penguins in the wild and how people can help preserve these charismatic birds’ natural habitat.
