Oregon State Park Ranger, Tyler Banks, called Think Wild’s hotline on Wednesday, June 26, after finding three river otter pups in a ditch along the road. The three pups were very lethargic, and one passed away shortly after they were found. The ranger called Oregon State Police Wildlife Officer, David Mackenzie, who transported the two surviving otter pups to Think Wild.
Upon intake, Think Wild rehabilitation staff found the two female infant otter pups to be lethargic and moderately dehydrated. They had dirt on their eyes and noses and plant seeds stuck in their fur. Staff administered fluids and antiparasitics and performed a full examination of the otters to determine their age (5-6 weeks old), weight (979 grams and 1120 grams), and tooth development, and to establish protocols for their care.
“River otters are highly intelligent and can easily become habituated to humans if proper precautions are not taken,” said Pauline Hice, Think Wild Director of Wildlife Rehabilitation. “Animals that become comfortable around humans cannot safely or humanely be returned to the wild, so we are taking extreme measures to ensure the otter pups do not associate humans or their scent with food or safety. Only senior rehabilitation staff treat and feed the patients and wear camouflage suits, boots, and masks.”
Unfortunately, Think Wild does not have an enclosure with the appropriate infrastructure for the long term rehabilitation of orphaned aquatic mammals like river otters and beavers. These animals require 8 months to 2 years of rehabilitative care when rescued as orphans. Their enclosures must include a pool with a filtration system, chew and dig-proof metal caging, and other species-specific enrichment and safety features. In fact, there are no facilities east of the Cascades with appropriate enclosures for river otter or beaver rehabilitation.
Fortunately, once the otter pups are stabilized, Think Wild has received approval from the Oregon Department of Fish and Wildlife to transfer the otter pups to the Wildlife Center of the North Coast in Astoria, Oregon, where they will be rehabilitated until they are old enough for release back to the wild. At that point, the otters will be transferred back to Central Oregon for release.
Think Wild is accepting donations and naming sponsorships to build an aquatic mammal enclosure on their 4-acre campus for the rehabilitation of otters and beavers. The organization has enclosure guidelines, blueprints, and care protocols, but needs funds to start the estimated $35,000 project.
