Internet sensation April the giraffe has still not gone into active labor keeping millions of people waiting to watch her give birth live on cam. On Wednesday evening, the upstate New York zoo that houses the pregnant animal said on Facebook that April’s backend has bulged significantly and she appeared distracted.

“Corey [a keeper] noted some changes this evening. April's backend has some significant ‘bulging’ occurring. … She was very ‘with it’ but then became very distracted and as Corey put it, ‘would have walked right through me.’ Though sounding intimidating; this behavior is what we will see — consistently — when in active labor. She will walk through her strong contractions and push push push,” Animal Adventure Park in Harpursville, New York, said in the evening update posted on Facebook.

The park, however, did not predict when the giraffe will give birth. In February, a live stream was set up to let people watch the 15-year-old giraffe give birth. At the time, the zoo said the pregnant animal was due at the end of that month or early March. However, several weeks have passed and yet there are no signs of April going into labor.

On Tuesday, the park said the live cam will remain through the giraffe’s active labor and they will not turn it off “unless instructed so by the vet team.” However, she may not be positioned the right way while giving birth.

“If she is facing the ‘wrong way’ — don't worry we have many other cameras capturing the process and will provide content soon after birth,” the park said.

A giraffe can be pregnant for 15 to 16 months and her labor can last anywhere between an hour to a full day. However, in April’s case, the park said they are hoping the calf would come out soon once she goes into labor.

“From what we have been told from prior facility — when she has her calves — she calves very quickly — which has us all on our toes as it is!” the park said Tuesday.

A newborn calf weighs about 150 pounds and is 6 feet tall on average.

This will be April’s fourth calf and 5-year-old mate Oliver's first calf. The calf is also reported to be the first giraffe offspring for Animal Adventure Park.
