There are two reasons to celebrate this month at Prague Zoo. After 14 months of gestation, two Rothschild Giraffe calves were born within days of each other. The first arrived on February 9, born to mom Nora, one of the best known animals at the Zoo. Nora is 13 years old and a very experienced mother -- this is her fifth baby and she successfully raised all but the first on her own. The father of the newborn is the twelve-year-old Johan. Their calf is a female and has been named Apolena.
