After keeping millions of people anxiously glued to their computer and phone screens on "belly watch" since Feb. 11, April the pregnant giraffe delivered her calf at Animal Adventure Park (AAP) in Harpursville, New York, on April 15.

The 15-year-old mother welcomed her newborn at 9:54 a.m. local time. This is April's fourth calf, the first to be conceived by her mate, 5-year-old Oliver, and the first baby giraffe born at AAP. (The announcement of the calf's gender will be made after its birth by a text alert system, according to the park.)

Barely into its first day of life, April's calf is already a YouTube sensation, with more than 561,000 YouTube viewers checking in to coo over the gangly baby at 11:24 a.m. The young giraffe will stick close to April and will be kept apart from its father until it is weaned, which can take about 6 to 10 months, AAP officials explained in a description for the live video feed streaming from April's indoor pen.

Here's how the birth went down this morning:

9:48 a.m.: The head appears.
9:53 a.m.: The baby's head, neck and shoulders are visible.
9:54 a.m.: The baby begins to slide from April's vulva and lands on the ground, a six-foot drop! April begins to clean the new arrival.
9:56 a.m.: The calf lifts its head and begins to look around.
10:07 a.m.: Jordan Patch, Animal Adventure Park (AAP) owner, ended the AAP Facebook Live transmission, saying: "We're gonna let mom and baby do their thing for a little bit." He said that the birth went perfectly, and that the baby was already nibbling at April, looking to nurse. "As soon as we know the gender, we'll let everybody know," Patch added.

As of 11:30 a.m., the calf was slowly walking around the enclosure, wobbly legs and all, with proud mama April continuing to give him or her a little saliva bath.

For weeks, April commanded a captivated internet audience as she ambled around her pen, her protruding belly showing ripples of activity when the fetus moved inside. During the week of March 13, some signs of impending birth became more pronounced, with "significant changes" visible, her caregivers reported on Facebook.

"Her back end has become significantly larger and relaxed, motion and pulsing in this area has been noted, and discharge has been observed," they wrote. However, April was not yet experiencing active labor, they explained.

On March 14, as winter storm Stella pounded the northeastern U.S., caregivers stayed overnight at the zoo to keep watch on their charges. April's behavior during the early morning hours prompted them to check in on her, but her condition remained unchanged from the prior evening, according to a keeper's report.

A female giraffe carries her fetus for 15 months, which might seem like a long time when compared to a human mother's 9-month pregnancy. But other mammals carry their young for even longer. Gestation lasts for up to 16 months in sperm whales and up to 18 months in killer whales, according to the National Oceanic and Atmospheric Administration (NOAA). And African elephants, the largest land animals alive today, gestate longer than any other mammal — 22 months, according to the World Wildlife Fund. [Infographic: For How Long Are Animals Pregnant?]
