POLAR BEAR PAYTON’S FIRST YEAR AT THE NORTH CAROLINA ZOO Story & Photos by Kristi Johnson Marion

Ayear ago, the North Carolina Zoo welcomed Payton, a 1,000-pound male polar bear to its Rocky Coast habitat. Payton was born and grew up at the Brookfield Zoo in Chicago and named after the late Chicago Bears NFL team running back Walter Payton. Now 18 years old, he was relocated from the Memphis Zoo in Tennessee on the recommendation of the Association of Zoos and Aquariums’ (AZA) Species Survival Plan (SSP) last January in hopes that he and the Zoo’s female polar bear, Anana, might produce a cub. Payton’s keepers have enjoyed working with him and getting to know him over this past year. Keeper Kirsten Perkins described his personality as “derpy,” or goofy. “He easily gets excited about things. He has big ears, and they perk up when he’s excited, and his head starts bobbing up and down.” He seems to enjoy playing with his enrichment items, including large plastic garbage cans perfect for a 1,000-pound polar bear. “He loves to put them on his head and fold them up into tiny pieces,” said Kirsten. “And it’s good for him to practice this natural instinctive ‘crushing’ behavior,” said Keeper Melissa Vindigni. Speaking of instinctual behavior, “We noticed that he seems to love how Kirsten smells,” explained Melissa. “Sometimes, we have her hug the enrichment items before we toss them to him.”

Polar bears have more olfactory nerve endings than other animals. Their brain is more dedicated to processing smells than its other senses. This excellent sense of smell is an evolutionary trait developed over thousands of years for survival. The polar bear's nose is so powerful it can smell a seal on the ice 20 miles away and sniff out a seal's den that has been covered with snow. Payton seems to be even more in-tune with his sense of smell than other polar bears our keepers have worked with in the past. “We notice that his nose is always working,” said Keeper Melissa. He seems to love forming relationships with keepers and eagerly participates in training sessions and oneon-one time with his keepers. “He’s good at making you feel special,” said Keeper Kirsten. Both polar bear habitats have pools and streams chilled year-round to 50°F in the winter and around 63°F in the summer. During his time at the North Carolina Zoo, keepers have enjoyed watching him grow as a swimmer. Keeper Melissa noted that his pool here at the North Carolina Zoo is deeper with more depth features than he was accustomed to at other zoos, so it has been a discovery process. It's been amazing watching him come out of his shell and swim more and more.” When Payton was first introduced to the Zoo’s 147,000 gallons pool, he’d like to hold onto the edge, much like a child learning to swim. Now, keepers say he’ll dive right in you toss something into the water. “Sometimes, he’ll find a perch for his front feet and take a nap in the pool,” said the keepers.

Polar bear mating season generally runs from February through March in the wild. Payton is being slowly introduced to the Zoo’s 22-year-old female polar bear Anana. She is roughly half his size at 600 pounds. In the wild, polar bears live an average of 15 to 18 years, although biologists have tagged a few bears in their early 30s. Under human care, bears can reach their mid-30s. Neither of the bears has sired cubs. At the Memphis Zoo, Payton was paired with another female (who happens to be Amana’s sister!) during mating seasons, but breeding was unsuccessful. North Carolina Zoo's
