The Pittsburgh Zoo & PPG Aquarium welcomed a highly anticipated pachyderm bundle of joy tonight when 25-year-old African elephant, Savannah, gave birth to a baby girl.

The birth was the first of elephants at the zoo since Savannah delivered Callee in 2000.

Zoo staff aren't saying much about the newborn, only that it was born about 4:30 p.m. and that baby, mother and father, Jackson, the zoo's resident bull elephant, are in good health.

"Everyone's doing fine right now," spokeswoman Tracy Gray said.

More details about the elephant will be revealed at a news conference tomorrow, she said.
