the park and a legislative grant having expired that day. An uproar ensued and the Council, on March 1, 2006, voted to transfer operations to the Society with a promised $4 million grant from the Michigan Legislature. The city retained ownership of the assets, including the Zoo in Royal Oak and the Belle Isle Nature Center in Detroit. The Society is responsible for governance, management and operations, including creating a plan to raise funds for long-term operations.. On August 5, 2008, voters in Macomb, Oakland, and Wayne counties overwhelmingly passed a zoo tax that provides sustainable funding to supplement earned revenue and philanthropic support. The Penguinarium was temporarily renamed the "Winguinarium" in 2009 while the Detroit Red Wings played the Pittsburgh Penguins in the 2009 NHL Stanley Cup Final. In 2011, the lions' enclosure was remodeled, providing animals more than double the room, new landscaping, and a glass wall to allow closer encounters with visitors. The Zoo also has the Simulator Ride, a 4-D Theater, the Tauber Family Railroad and a carousel. In 2013, the Zoo celebrated its single largest donation ever ($10 million) by announcing plans for the Polk Penguin Conservation Center (PPCC), which opened in 2016. The Center replaces the Penguinarium (which itself was revolutionary when built in 1968) and became the world's largest facility dedicated to the study of penguins. The Penguinarium will be converted into event space. In 2017, a biodigester was installed to convert manure and food waste into methane, which is then used to power the zoo's animal hospital. In September 2019, the Penguin Center was closed for waterproofing repairs. The penguins were moved back to the original Penguinarium (their home from 1968 to 2015) until the Polk Center reopened. The center reopened on February 14, 2022 after delays due to the COVID-19 pandemic. It contains 5 species of penguins; King, Macaroni, Gentoo, Chinstrap and Rockhopper. On July 6, 2019, the Zoo celebrated the birth of Keti, a red panda cub, born after a 4-month gestation period.
