Three male Amur tiger cubs were born Tuesday (April 21) at the Columbus Zoo and Aquarium in Powell, Ohio.
The baby tigers each weighed 2.5 pounds (1.1 kilograms) at birth, which falls within the typical range of 1.5 to 3 pounds (0.7 to 1.4 kg) for tiger cubs, according to zoo staff. An animal care team monitored the babies closely over a live video feed, and when their mothers maternal instincts didnt kick in, the team rushed in to nurse and care for the cubs themselves.

Caretakers at the zoo were worried that the cubs' mother, 10-year-old Irisa, would never conceive. At such an old age and with one undersized ovary, "there were a number of strikes against her," said Harry Peachey, curator of Asia Quest at the Columbus Zoo.
But sure enough, Irisa bred with 11-year-old Foli in early January. Foli has two other litters to his name, and has since been moved to another zoo, based on a recommendation by the Species Survival Plan , which manages populations of endangered species within most U.S. zoos.
At the end of last week, Irisa was on the verge of going into labor , but her behavior was abnormal, according to Peachey. Although she stopped eating, she refrained from moving into the den, where most mothers-to-be quickly go for privacy.
After days of this odd behavior, she finally found solitude in the den and her birth went relatively smoothly, zoo officials said. The first cub was born at 12:40 a.m. local time, and the last arrived at about 2:23 a.m.
But Irisa's maternal instincts never really kicked in. "She did nurse one cub, but she didnt nurse the other two," Peachey told Live Science. "And she wasnt bringing them toward her. She wasnt doing all the things that we regard as normal maternal behavior."
Soon, Irisa left the den altogether and climbed up onto a shelf, where she couldnt be reached.
But the tiger cubs were hungry and they called for their mother. By 6 a.m. local time, Irisa had had enough, zoo officials said. She got off the shelf, walked into the den, and covered her three cubs with straw. At that point, Peachey and his team headed in. She didnt do anything aggressive but that was a pretty good signal that she might, Peachey said.
The cubs are now being hand-reared by the zoo's animal keepers, meaning theyre incubated and on a feeding schedule. This is only the zoos second litter of tiger cubs , but theyre experienced in caring for the little guys, Peachey said. The zoo's first litter also needed to be hand-reared after an electrical storm sparked a power outage.
Amur tigers are critically endangered. Currently, there are fewer than 150 Amur tigers in all of the associated zoos and aquariums in North America. According to Peachey, there are likely only 400 Amur tigers remaining in the wild. The number one cause of mortality for these animals is humans, and it's estimated that humans directly cause 80 percent of tiger deaths.

bf....I agree 10% !!
I'm very happy that the will survive. But, on another note, the destruction we have done to the environment which directly affect animal survival, is a real black mark on our species.
Sometimes we humans just don't know when to leave things alone......sigh...
I agree BF. I cannot stand to see an animal caged in a zoo.
I have been fighting for animal rights and our environment for decades. It is the Creators gift to us, and we destroying it. Sad.
Very true Kav. We keep trying to invade THEIR territory. Leave them alone!!
