Updated June 21: Revised to include the giraffe's public debut.

The public can now see the smallest member of the Dallas Zoo's giraffe family out in the Giants of the Savanna.

Tsavo made his public debut Wednesday in the giraffe feeding yard, and will now be making regular appearances.

He was almost 6 feet tall when he was born about 1:45 p.m. May 30 after an hourlong delivery. The baby weighed about 150 pounds at a checkup two days after birth.

He was named as a tribute to the Tsavo National Park in Kenya, which is home Masai giraffes.

The reticulated giraffe spent its first couple of days learning to walk and nurse, and followed his mother, Katie, around. The other members of the herd have been watching the calf curiously in the maternity stall, which has extra-soft sand to cushion the 6-foot fall.

Katie and the calf bonded off-exhibit and he was introduced to other members of the herd, including Auggie, the zoo's "oldest and most patient giraffe" who is typically first in line to meet the newborns, and Jade, the zoo said.

"We consider ourselves so lucky to get to welcome this (big) little guy to the world here at the Dallas Zoo," Harrison Edell, vice president of animal operations and welfare, said in a written statement. "Katie brought this calf into the world like a pro, and we continue to be amazed at how quickly this baby giraffe is taking to his surroundings and learning his way with Katie there to guide him."

Of course this is nothing new for Katie, who has been pregnant since February 2016. The baby boy is Katie's third calf and first son.

But the zoo, which has had a busy spring, took a different approach this time -- choosing to wait until April to announce Katie's pregnancy. As the birthday neared, keepers worked in shifts to watch Katie 24-7 for signs she was ready to deliver.

When she finally did, it was away from the cameras and live-stream that made Katie world famous in 2015.

Kipenzi, the last calf to be born at the zoo, died in an accident a little less than four months after she was born. The zoo said it plans to install baby-proofing barriers around the perimeter of the Giants of the Savanna so the fencing is more obvious to a calf.

This was also father Tebogo's third calf. He was matched with Katie on a breeding recommendation from the Association of Zoo's and Aquariums' Species Survival Plan.

Dallas Zoo President and CEO Gregg Hudson said the baby's birth was "yet another milestone in what has been a very exciting year for us."

The zoo opened its long-awaited hippo exhibit in April. A month earlier, it celebrated the birth of its first lion cub in 43 years.

"We look forward to sharing the adorable awkwardness and cute baby face of the giraffe calf with our visitors," Hudson said in a written statement. "But we also want our guests to know how critical a role accredited zoos have in conservation efforts, as we try to help maintain the species' existence given the numbers in the wild are diminishing so rapidly."
