Tulsa Zoo Celebrates 21st Birthday Of Its Tallest Resident

The Tulsa Zoo celebrated a tall birthday boy Thursday.

Zoo workers threw a party for Samburu the giraffe's 21st birthday.

They had special treats and fruits on hand, and of course, a standard cake wouldn't do, so workers fixed up treats in a birthday tree instead.

On Sunday, the Tulsa Zoo will celebrate Mother's Day by offering half-price admission to all guests.
