It’s a cool, wet spring morning at Northwest Trek, and keeper Wendi is cleaning out the skunk habitat. She scoops some poop, then bends down intently. “Aha!” she exclaims, and reaches out a gloved hand. It’s a banana slug, long, mottled and yellow – and Wendi scoops it up in all its slimy glory. Slug Fest is coming, and Northwest Trek is getting ready. Slug Hunt “Fifty to sixty degrees and raining, that’s prime slug hunting time,” explains Wendi. One of the Wetlands keepers, she’s taking part in the staff’s Longest Slug Contest for the ever-popular annual Slug Fest event, …

Northwest Trek Wildlife Park welcomed two American bison calves in less than a week, marking an exciting start to spring in the wildlife park’s 435-acre Free-Roaming Area. The first calf, a male named Torrent, was born to mother Rainy on May 8 during Mother’s Day weekend. A second calf, whose sex and name have yet to be determined, was born to mother Cloudy on May 13. Both calves are thriving alongside the park’s bison herd. Keepers had been closely monitoring the expectant mothers, who were nearing the end of the typical 285-day gestation period. In keeping with natural bison …
Ruzco, a nearly 4-year-old caribou who recently joined Northwest Trek’s herd, is settling in well in the wildlife park’s 435-acre Free-Roaming Area with his fellow caribou. He is also exploring the expansive habitat alongside mountain goats, moose, bison, elk, deer, and bighorn sheep. Caribou (Rangifer tarandus) are one of the largest members of the deer family. Their diet is diverse, including mosses, lichens, grasses, and tender shoots. Breeding season begins in September, when bulls shed the velvet from their antlers in striking red displays and may engage in brief but intense battles. After about eight months, females usually give birth …
Rescued, resilient, and now thriving, male cougar Sullivan is celebrating his one-year anniversary at Northwest Trek. To mark the milestone, Sullivan enjoyed a special carcass feed. This enrichment activity encourages natural behaviors like chewing, tearing, and problem-solving while keeping him physically and mentally engaged. Sullivan’s journey began when he was found alone as a young cub in critical condition, severely malnourished and dehydrated. With dedicated, round-the-clock care from the animal care team, he made an incredible recovery. Today, Sullivan continues to grow stronger, exploring his habitat and showing the instincts that make cougars such powerful and adaptable animals.
For many, it’s a late-winter hobby, but for the keepers in Northwest Trek Wildlife Park’s 435-acre Free-Roaming Area, it’s just another part of their job: shed hunting. The bull (male) elk are beginning to drop their antlers—a yearly occurrence that happens a few months after breeding season due to a decrease in testosterone. “We’ve already seen some impressively large antlers drop,” said assistant curator Dave. When a bull elk drops its antlers, they immediately begin growing a new set. “Antler grows faster than any other bone,” said Dave. “During the summer months, bull elk antlers can grow up to …
We’re excited to welcome a new feathered resident to Northwest Trek Wildlife Park. Alba, a barn owl, recently arrived and is already beginning to settle into life at Northwest Trek. Alba joins us from the Palo Alto Children’s Museum and has completed a full wellness exam with our veterinary team. With a clean bill of health, he’s officially ready to meet guests and can be seen in the barn owl habitat. Like many raptors, Alba is taking things at his own pace (very owl of him). Raptors don’t always reveal their personalities right away, and that’s perfectly okay. Our animal …

Cougar cubs Sienna and Sullivan continue to grow in both health and confidence. The latest weigh-ins show Sienna at about 60 pounds and Sullivan at 77 pounds. Although Sullivan is larger, both cubs are gaining weight at the same steady rate, a strong sign that each is getting exactly what they need from their balanced diet. Since arriving as orphaned wild cubs, Sienna and Sullivan have undergone a remarkable transformation. Keeper Haley has had a front-row seat to their progress. “Both Sienna and Sullivan have overcome so many challenges,” said Haley. “Sullivan adapted quickly and shows amazing resilience, even with …
Looking for a meaningful way to treat your pet this holiday season? At Northwest Trek Wildlife Park, enrichment isn’t an extra, it’s an essential part of caring for animals. Whether it’s gray wolves following scent trails, bears investigating puzzle feeders, or skunks foraging for treats, every enrichment opportunity helps animals think, explore, and behave like they naturally would in the wild. “We offer a variety of enrichment types to target specific natural behaviors we know our animals are capable of,” explains Haley, keeper and Behavioral Husbandry Coordinator at Northwest Trek. “The more we learn about an individual animal, like how …
Brrr! You can feel the chill in the air as the temperature drops. You’re likely pulling out your winter coats, if you haven’t already! Many of the animals at the wildlife park also have their winter coats ready and are well-prepared for the colder weather. Wolverine Wolverines are made for the cold- and our wolverine Rainier is no exception. Wolverines are well-adapted for winter living, with extremely dense fur, large snowshoe-like paws that allow them to stay on top of deep snow and crampon-like claws that enable them to climb up and over steep cliffs and snow-covered peaks. Their thick …
