April the giraffe has not had her baby, even though she’s seemingly been on the verge of active labor for weeks. When the Animal Adventure Park in upstate New York started the YouTube live stream in February, they promised April was due any day. Nearly two months later, there was no sign of a baby. So how long are giraffes pregnant for?

On average, the gestation period for giraffes is 13 to 15 months. A male giraffe knows if a female is fertile by tasting her urine, according to Taronga.org.au. They are the tallest animals, with males growing to 20-feet and weighing up to 2,600 pounds. Females, on the other hand, usually grow to 15-feet and weigh 1,800 pounds.

Giraffe mothers give birth standing up, which means the calf falls nearly 6-feet to the ground. The fall breaks the pregnancy sac that encloses the calf and helps it breathe.

Animal Adventure Park might have gotten their due date wrong. Even though cranky viewers of live stream assumed as much, this notion was confirmed by a zookeeper in the United Kingdom.

When asked by This Morning host Holly Willoughby asked Thursday why April was taking so long, a zookeeper at the Chester zoo in the U.K. replied, “I’m not too sure about that… Maybe they’ve got their date wrong.”

Animal Adventure Park didn’t respond to possibly getting April’s due date wrong, but they continued to update their Facebook page with the latest developments about the giraffe’s pregnancy.

“Keepers report is that April has consumed all of last evening's grain offering, and continues to eat her hay,” the zoo reported Friday. “Udders are full, wax caps have reappeared (as they will come and go at times), and she is very much ‘herself.’”
