Rare Amur Tiger Cubs Debuting at Minnesota Zoo Raise Hopes for This Species

A pair of rare Amur tiger cubs are making their public debut at the Minnesota Zoo, raising hopes for preserving an endangered species that’s native to far eastern Russia and northern China.

Andrei and Amaliya got to venture outside and feel the grass of their new home under their paws Wednesday for the first time since their 12-year-old mother, Dari, gave birth on May 23, The AP reported.

“They’ve done quite well since then,” zoologist Trista Fischer said. “We’ve monitored them very closely. Dari’s been fantastic. She’s provided outstanding maternal care. And so today we’ve reached the point where they’re fully vaccinated and they’re now about 40 to 45 pounds (18-20 kilograms).”

Scientists estimate the Amur tiger population is just around 400 to 500 in the wild. They were near the brink of extinction in the 1930s and 1940s but have recovered somewhat since then. It’s tricky to breed them, and around one in four Amur cubs don’t make it to adulthood, whether it’s in the wild or in captivity, she said. Poachers are another major threat.

But the Minnesota Zoo, located in the Minneapolis suburb of Apple Valley, has a long history of conserving tigers. Its Amur tigers have produced 57 cubs, 46 of which survived for at least 30 days. Of those 46, 21 have gone on to produce litters of their own, amounting to another 86 cubs. The births of Andrei and Amaliya raised the zoo’s population to seven Amur tigers, including their sire, Luka.

Fischer is the leading coordinator for the Tiger Species Survival Plan, a breeding program in the United States with facilities in other countries that works on a global level to preserve the big cats. The plan manages three groups of tigers: Sumatran, Malayan and Amur.

“This litter is so valuable to the population right now,” she explained, saying the genetic diversity of heathy tigers in human care could someday be used to help support populations in the wild.

Zoo spokesperson Zach Nugent said the cubs will remain housed together with their mom for about 18 months, before Andrei, the male, is moved to separate housing, around the same time a male cub in the wild would start venturing out on his own. Amaliya, the female, may spend a little more time with Dari, up to 24 months. Then Fischer will determine whether either cub should be bred, and potentially moved for that to another accredited zoo, which typically happens after the cubs are 2 years old.

“Aww, I love when they get their little Yoda ears,” Fischer said referring to the pointy ears of the Star Wars character as she watched Amaliya and Andrei explore the new terrain of their enclosure. She said it was an emotional, exciting and proud moment for her and her team.

“Our work’s not over, but all that work so far is really paying off in how well that these cubs are acclimating to a new surrounding, pretty much immediately,” she said as the little tigers roamed outside with their mother. “They’re showing a lot of resiliency, which is something that we work hard for in human care. We want these animals to have a lot of confidence and be able to adapt to new environments just as they’re doing today.”

An "amphibious mouse" with partially webbed feet that eats aquatic insects was among 27 new species discovered during a 2022 expedition to Peru's Amazon, according to Conservation International.

Scientists also discovered a spiny mouse, a squirrel, eight types of fish, three amphibians and 10 types of butterflies, Trond Larsen, head of Conservation International's Rapid Assessment Program, told Reuters this week.

He added that another 48 species found by investigators were potentially new, but needed further study.

The new species were found in Alto Mayo, a protected area with several ecosystems, Indigenous territories and villages.

"Discovering so many new species of mammals and vertebrates is really incredible, especially in such a human-influenced landscape as Alto Mayo," Larsen said.

The expedition between June and July 2022 was made up of 13 scientists plus local technicians and members of Indigenous groups.

"It was really fantastic to work so closely with the Awajun people. They have extensive traditional knowledge about the forests, animals and plants they live side-by-side with," Larsen said.

Among the new species, Larsen highlighted the spiny mouse that has stiff fur, the amphibious mouse, and a dwarf squirrel that measures 14 cm (5.5 in).

"(The squirrel) fits so easily in the palm of your hand. Adorable and beautiful chestnut-brown color, very fast," Larsen said. "It jumps quickly and hides in the trees."

Another favorite discovery was the blob-headed fish, a type of armored catfish, he said.

A total of 2,046 species were recorded during the 38-day expedition using camera traps, bioacoustic sensors and DNA sampling. Among them, 49 were classified as threatened, including the yellow-tailed woolly monkey and the tree monkey.

Larsen said the discoveries reinforced the need to protect the area.

"Unless steps are taken now to safeguard these sites and help restore parts of the landscape ... there's a strong chance they won't persist in the long term," Larsen said.
