The name was the winning entry in the zoo's online contest. The giraffe will be called "Taj" for short.
The zoo's live stream of April's pregnancy was the second most live-viewed channel in YouTube's history, with more than 232 million live views from late February through Taj's birth. More than 1.2 million viewers were watching when April gave birth.
The contest to name the calf charged $1 per vote. The proceeds will be split among zoo upgrades, wild giraffe conservation and for children with unexpected medical expenses.
