However, the vet says he's not concerned by the fact that April has not yet given birth, and he says viewers shouldn't be anxious either.
April, the giraffe that has captivated the world after a YouTube incident last month, appears to have gone into labor.
April has even become so popular that some are wondering if the whole pregnancy is giant park conspiracy- especially given her timely name.
"Meanwhile, AAP said", Our big girl is comfortable, confident, and continues to keep her composure - better than the rest of us!" "Keep April and our team in your positive thoughts", the post said.
A discharge was reported earlier in the week.
Animal Adventure Park has a webcam in April's quarters, capturing all the moments leading up to the birth.
Hopefully all of this attention for April brings more attention to endangered animals worldwide, too. The camera was back up soon after.
"We can not retain offspring, as it would lead to incestuous mating and undermine the genetics of the program and species", the zoo says.
Patch also made sure to point out that giraffes are known to hide their labor signs.
This is no joke: As hundreds of thousands of people watched, the mama giraffe waited patiently for April Fools' Day and the day after to pass without giving birth. This is Oliver's first calf, but April knows the drill - this will be her fourth.
The little giraffe won't be all that little. The calf will weigh around 150 pounds and be approximately 6-feet-tall at birth. Patch blamed "a handful of extremists and animal rights activists" for the interruption.
Animal Adventure Park is now in its off-season and the park is closed to visitors.
The vet for April the giraffe learned a very valuable lesson - don't predict when the world's most famous giraffe will give birth.
