According to the owner of Animal Adventure Park in Harpusville, New York, "animal rights activists" falsely reported the video as a way to protest the captivity of the giraffe, who is named April.
The video was shut down earlier by YouTube because of "sexually explicit content".
He said that kicking the livestream offline had removed an educational tool from the web.
April's fans have stayed loyal to the live stream, waiting for the big moment.
The stream was later restored, and more than 53,000 people were watching the stream live as of about 3:10 p.m. MT Saturday. At birth it will weigh in at about 150 lb. and will stand at about 6' tall, Animal Adventure Park said.
Giraffes can be in labor anywhere from two to six hours, and up to a full day; but once the calf begins to show, it should be fully out in under an hour. A giraffe's pregnancy lasts about 15 months.
April is 15-years-old and this will be her 4th calf. Oliver, the father, is five and this is his first calf.
This is the first time the zoo received such criticism. "Bulls take no part in rearing young".
