Natural Bridge, VA - (AP) - Virginia's Natural Bridge Zoo has two more members of its giraffe family.
Twin giraffes were born at the zoo on Friday.
Zookeeper Debbie Mogensen says she didn't know the mother was carrying twins and that the births come as a surprise.
Zoo worker Charissa Sangster says the mother is older, and employees initially thought she was going to have one big baby giraffe.
The latest giraffes are yet to be named and stand nearly six feet tall.
Another zoo giraffe is expected to give birth in August.
