The Birmingham Zoo invites the community to give back to those in need this holiday season. On Saturday, November 18 and Sunday, November 19, Zoo visitors can enjoy half-price admission by bringing any canned or non-perishable food item. On this particular weekend, guests who donate a food item to the United Way Food Bank will pay $8 (plus tax) for adults, $7 (plus tax) for senior citizens 65 years and older, $7 (plus tax) for military, and $5.50 (plus tax) for children 2-12 years old. Children under age two are free. The Zoo requests that visitors bring one item per person to receive the discount.
