SYRACUSE, N.Y. -- Everyone's invited to a special birthday party in Syracuse Sunday.

The Rosamond Gifford Zoo will be celebrating the first birthday of its three tiger cubs. Yuri, Kuza and Misha were born on May 7th, 2011 and they've been a very popular attraction at the zoo ever since.

As part of their birthday celebration, visitors to the zoo will be able to make a tiger puppet, sign a birthday card, and enjoy tiger-themed snacks. There will also be a special sing-a-long of Happy Birthday at 1 p.m.

The celebration is included in the regular zoo admission.
