The Houston Zoo's baby orangutan is celebrated her first birthday Saturday.

Aurora climbed on her mother's back to get a better look at the streamers and presents decorating her exhibit.

Mom opened some of the boxes to find treats inside.

Visitors looked on and signed a giant card wishing Aurora a happy birthday.
