You may see a lot of new faces—and places—when The Maryland Zoo in Baltimore opens its doors seven days a week starting March 1.

Over the winter, the zoo gained a boatload of new animals, through births and acquisitions—including adorable lion cubs Luke, Leia, and Zuri; a baby black-and-white colobus monkey named Gonzo; and two 1-year-old reticulated giraffes Anuli and Juma, pictured.

“We are very happy to have them join the herd,” says Carey Ricciardone, mammal collection and conservation manager. “The two young females have been acclimating nicely to the Giraffe House and are very cooperative with the keepers.”

Additionally, in the spring, the zoo is reopening its Marsh Aviary and African Aviary, both of which sustained extensive damage in the 2010 blizzards.

Another long-term build is the new $10.4-million African Penguin Exhibit, which debuts in the fall and will double the number of birds and include underwater-viewing features and a wave pool.

The viewers will be able to see the penguins from every angle possible,” says Don Hutchinson, the zoo’s president/CEO. “We think this new exhibit will redefine the zoo.”
