SF Zoo celebrates baby gorilla's first birthday

SAN FRANCISCO

He is now 1-year-old.

He was treated with an ice cream cake filled with treats. Zoo members and children participated in the festivities, eating cupcakes and wearing birthday hats.

Hasani's birth mother abandoned him after birth, but the zoo trained another female to become a surrogate.

Tuesday also kicks off the zoo's month-long "Winter Goes Wild" holiday celebration.
