Ears, Eyes, Fur: A River Otter Exam

One of Northwest Trek Wildlife Park’s resident river otters, Blakely, recently had a dentist appointment to fix a fractured tooth. Blakely traveled with Northwest Trek’s head veterinarian, Dr. Allison Case, to sister zoo Point Defiance Zoo & Aquarium’s healthcare hospital for the exam. Typically, Blakely would be treated at Northwest Trek, but the dentist was already at Point Defiance Zoo treating a tiger for a similar dental issue. Dr. Alice Sievers, a board-certified veterinary dentist and one of only 250 veterinary dental specialists in the world, volunteered her time with veterinary assistant Sharon Ghormley and veterinary technician Taylor Parker, all …

On a recent December afternoon, Northwest Trek Wildlife Park staff members spent time doing what might look like arts and crafts to an outsider. But to the keepers and animals, those arts and crafts are an essential part of the everyday life of the animals; it’s enrichment. Enrichment items are things like food, smells, or toys that enhance the health and well-being of the animals in our care. Using these items in combination with knowledge of species’ natural history and behaviors, animal keepers can provide unique experiences that enhance the animal’s overall welfare. During Northwest Trek’s annual Winter Wildland, running …

A hoary marmot living in Mount Rainier National Park now calls Northwest Trek Wildlife Park home and will make his public debut on Friday, Nov. 10. The young marmot, estimated to be born in spring 2022, was fed human food and began aggressively begging for food from people in the national park. According to Mount Rainier National Park officials, the animal had become a danger to himself and people. “Food-conditioned animals will beg aggressively for food and may bite, causing serious injury and possible infection to people,” said Dr. Tara Chestnut, former wildlife ecologist for Mount Rainier National Park. “Feeding …

Northwest Trek Wildlife Park is now home to two female yearling American bison. The bison will soon join the wildlife park’s 12 other bison in the 435-acre Free-Roaming Area. “We expect them to fit right in with the herd,” said Marc Heinzman, the wildlife park’s curator. “They are at an age where they are usually more curious but less confident than an adult might be.” Before they join the others, the duo – named Cloudy and Frosty by keepers – are acclimating to their Northwest home behind the scenes. They recently received wellness exams from the park’s two veterinarians, veterinary …

Ever wonder what it takes to feed an entire wildlife park? The keepers at Northwest Trek feed nearly 200 animals a day. It takes a specific science to prepare proper diets for all the different animals. “Each animal has a balanced diet based on its species, age, and any health-related issues,” said Northwest Trek curator Marc Heinzman. For example, the grizzly bears each eat 30 pounds of food daily during the summer. Their diet consists of fish, fruits, and leafy greens as they prepare for winter 2023’s torpor season. “The bears need to put on extra weight leading up to …

Endangered northern leopard frogs have been growing at Northwest Trek Wildlife Park! We first received the frogs as eggs in early May from Washington Department of Fish and Wildlife (WDFW) officials. Since then, we’ve seen them evolve into tadpoles and froglets. In their latest growth stage, experts at Northwest Trek came together to tag the frogs with a blue “dot” inserted into one foot. This method will allow scientists to spot them in the future and assess the success of this conservation project. Northern leopard frogs are an endangered species. Once thriving in the Pacific Northwest, they are vanishing due …

To train any animal, you need their trust! A blood draw can be one of the most challenging behaviors – especially for a 478-pound bear – and one that has taken keeper Haley and black bear Benton nearly two months to achieve. When animals participate in their own healthcare, everyone wins! Watch as carnivore keeper Haley patiently works with 15-year-old Benton behind the scenes on blood draw training with a blunt syringe as a training device. Benton carefully presents his massive paw through a bear paw-sized opening in the training space as Haley coaches him and then uses tasty honey …

National Zookeeper Week takes place July 18-24 this year. The week is devoted to sharing the passion and dedication of keepers. Our zookeepers are a dedicated group of people who work tirelessly each day to provide the animals with the best care possible. Rain or shine, keepers must be ready for anything 365 days a year. They are involved in the lives of the animals they care for often from birth to death and every moment in between, creating lifelong bonds. Whether it’s rearranging an animal’s “furniture” in their habitat to keep them new, fresh, and exciting, helping with medical …

Black bears Fern and Benton are long-time residents of Northwest Trek Wildlife Park. And the veterinary teams at Northwest Trek and Point Defiance Zoo & Aquarium have a long-standing history of joining forces. So, when it was time for the bears’ triennial wellness exams, Northwest Trek head veterinarian Dr. Allison Case invited Zoo intern veterinarian Dr. Cassidy Soehnlein to participate. The Exams Routine wellness exams are a critical component of animal well-being. With regular check-ups, the veterinary staff (veterinarian) can monitor the health of Fern and Benton. They can also act quickly if any concerns arise. Both black bears received …

It’s a chilly spring evening and the sun is sinking as nighttime begins. It’s darker here in rural Eatonville, away from city lights and cocooned in a blanket of clouds that hide the moon’s light. The illumination now comes only in beams from headlamps worn by a dozen or so scientists, students, researchers, and volunteers waiting for tiny bats to emerge from their slumber. They are at Northwest Trek Wildlife Park, home to more than 350 bats and one of the largest colonies in South Puget Sound. The goal tonight is to capture 50 bats to further their work toward …
