Two Magellanic penguin chicks graduated from the San Francisco Zoo's "fish school" Saturday morning, a zoo spokesman said.
Erin and Steve, the two chicks, waddled around Penguin Island at about 10 a.m. before keepers guided them to a place where they could jump in the water, spokesman Danny Latham said.
The two chicks were born in mid-May, since learning how to swim and getting adjusted to being hand-fed, Latham said.
The Zoo's annual March of the Penguins event celebrates the graduation of penguins from Fish School.
Several hundred people attended Saturday's celebration, Latham said. The zoo has the largest colony of Magellanic penguins in any U.S. zoo or aquarium.
Saturday's celebration also included face-painting and crafts, games, and animal artwork.
Zookeepers feed the colony twice a day. Erin has a red band on one wing and Steve a blue band, he said.
