The zoo began livestreaming the giraffe on February 23 and she has gained worldwide attention as several thousand people watched daily, waiting to see the birth.
April the giraffe has given birth at a NY zoo as more than a million people around the world watched live. A live camera feed shows the expecting mama's pen at Animal Adventure Park in Harpursville, New York.
There are more than 200,000 people tuned into the zoo's Facebook Live stream at 8am, eagerly anticipating the birth, as of Saturday morning.
The privately owned zoo began livestreaming from April's enclosure in February.
People across the country have been watching the live stream for weeks in anticipation of April's baby being born, and the wait has ended.
The calf is expected to weigh about 150 pounds (68.04 kilograms) and be about 6 feet (1.83 meters) tall. Eventually, the baby giraffe, April's fourth, will be moved to another facility. Some people even thought that the whole thing was a clever April Fools' Day joke.More news: April the giraffe welcomes much-anticipated calf
The park sent out an alert over its paid first-alert message system around 7:30 a.m.
It was quickly restored, and has attracted millions of loyal viewers since.
Female giraffes typically gestate for 15 months on average.
The calf's front hooves appeared first followed by the snout Saturday morning, an indication that the birth was imminent.
The money the park earned as a result of April's popularity is going to good use. The park has announced that the gender will be revealed at a later date, and that it will be holding a campaign to name the calf.
