ALBUQUERQUE, N.M.—Officials at the Albuquerque BioPark say they have a new resident.

Some zoo visitors were lucky enough to see the birth of the giraffe calf Saturday morning.

The baby giraffe learned how to stand and take its first steps inside the giraffe yard as it was surrounded by its mother, an 18-year-old giraffe named June, and two other female giraffes. Officials say the calf was on its feet and walking within 40 minutes.

The BioPark posted photographs of the new giraffe on its Facebook page Saturday afternoon.

Zookeepers and veterinarians are keeping a close eye on the newborn. They're not sure yet whether it's a boy or girl.

Native to the grasslands of Africa, giraffes usually weigh between 120-150 pounds at birth.
