Buffalo Zoo has sneak peek of Sakari, the polar bear

The Buffalo Zoo will introduce its newest resident, a 4-year-old male polar bear named Sakari, to the general public on New Year’s Day after a three polar bear exchange last month.

Cincinatti Zoo’s bear Berit went to Henry Vilas Zoo in Madison, WI where Sakari had been living.

Buffalo Zoo sent Anana to Cincinnati in exchange in November.

“The population of polar bears in our Zoos is declining and reproductive rates are low, therefore it is essential that Zoos all work together and exchange bears when necessary to provide the best chances for reproductive success,” said Dr. Terri Roth, Director of the Zoo’s Center for Conservation & Research of Endangered Wildlife (CREW). “Our Zoo population can be a critical resource for scientists studying the impact of climate change on this arctic icon.”

The complicated, multi-Zoo shuffle was recommended by the polar bear Species Survival Plan (SSP), the Association of Zoos and Aquariums’ (AZA) advisory group that manages the population in North American Zoos when it became clear that 17-year-old Berit and her mate, 26-year-old Little One, were not going to produce offspring.

“Berit and Little One have been together since 2007 and, although they have demonstrated appropriate breeding behaviors, Berit has never produced cubs,” said Dr. Erin Curry, the reproductive physiologist at Cincinnati Zoo’s CREW dedicated to polar bear research. “Anana is of prime reproductive age (16) and has produced cubs in the past, but due to the current shortage of sexually mature males in the population, she is left without a male to breed. Because Little One is genetically valuable, he and Anana were deemed a good match by the Polar Bear SSP. While we will be sad to say good-bye to Berit, the recommended moves are in the best interest of the polar bear population as a whole, and we are excited at the possibility of Little One becoming a father and passing on his genes to future generations.”

After settling into her new home, Berit will be introduced to a four-year-old female named Suka.

Sakari, Suka’s brother, will be a companion and possibly a future mate to Anana’s cub, Luna, who was born at the Buffalo Zoo in 2012 and is roughly the same age. Anana will join Little One in Cincinnati and, if all goes well, could breed this spring and produce cubs as early as next fall.

CREW monitors the reproduction of polar bears living in Zoos throughout North America and will continue to monitor Berit.

“Studying bears in Zoos provides unique opportunities for research that would not be feasible with wild bears. Because it is challenging to collect serial samples from the same bear in a field setting, scientists use bears like Berit, Little One and Anana as models to learn more about the complex physiology of this species,” said Curry.

“While we are sad to see Sakari go, we know that we are helping preserve the population of polar bears in North America by sending him to Buffalo Zoo to be with Luna.” said Henry Vilas Zoo Director, Ronda Schwetz. “We are very excited to be receiving Berit from Cincinnati and look forward to working with CREW to learn about advanced AI techniques for polar bears and hopefully produce cubs in the future.”

The Cincinnati Zoo is proud to partner with Polar Bears International as an Arctic Ambassador Center to help spearhead community efforts to reduce carbon dioxide and to educate visitors about global warming and wildlife conservation. Polar bears live in remote areas making them difficult and expensive to study.

Monitoring and surveying them is challenging. Therefore, scientists don’t have solid figures on the total number of polar bears worldwide. The most recent IUCN report estimates that there are 26,000 polar bears left in the wild and lists it as a vulnerable species, citing loss of Arctic sea ice due to climate change as its most serious threat.
