PORTLAND, Ore. - Tilly’s pups are on the move — sort of. The 4-week-old river otters at the Oregon Zoo, one female and one male, now weigh about 2 pounds each and have begun taking their first, tentative steps. The next step, keepers say, is to give them names -- and you can help.
“The little ones haven’t opened their eyes yet, but they’re growing fast and getting more mobile,” said Julie Christie, senior keeper for the zoo’s North America section. “They usually don’t travel too far when their eyes are closed. We think it’s time to name them before they really start to roam around.”
Christie and the other keepers have come up with a short list of possible names for each pup and are inviting the public to weigh in on the zoo’s website: www.oregonzoo.org. Votes will be accepted through Wednesday, April 5, and the zoo will announce the winning names on Thursday, April 6.
“For river otters, we like to choose names based on local waterways,” Christie said. “River otters are sensitive to water pollution, but we’re fortunate to live in a region that supports a healthy otter population. We want these pups’ names to highlight the importance of protecting our rivers, streams and wetlands.”
For the female pup, keepers are considering the following names (and nicknames):
· Abiqua (Abby): a Pudding River tributary originating in the Cascades foothills near Lookout Mountain.
· Calapooia (Cali): a Willamette tributary that flows generally northwest from its source near Tidbits Mountain.
· Nehalem (Nellie): a river that flows nearly 120 miles from the Coast Range down to Nehalem Bay.
For the male pup, keepers have narrowed it down to the following:
· Nestucca (Tucker): a forested river near the coast, known for its steelhead and salmon.
· John Day (J.D.): a Columbia tributary that is undammed along its entire 284 miles — the third-longest free-flowing river in the contiguous U.S.
· Wallooskee (Skeeter): a 10-mile tributary of the Youngs River in northwest Oregon.
Tilly, named after the Tillamook River, was found orphaned near Johnson Creek in 2009. She was about 4 months old, had been wounded by an animal attack and was seriously malnourished. Once her health had stabilized, Tilly came to the Oregon Zoo in a transfer facilitated by the Oregon Department of Fish and Wildlife, which oversees the species’ protection.
“She was a tough little otter,” recalled curator Amy Cutting, who oversees the zoo’s North America section. “She was in really bad shape when she was found, so it’s great to see her doing well now and raising pups of her own. She’s been a terrific mom.”
Christie said Tilly has started making other den areas in her behind-the-scenes area, and she continues to take some “mom time” when she needs a break.
The pup’s father, B.C. (short for Buttercup), also had a rough start to life. Orphaned near Star City, Ark., in 2009, he was initially taken in by the Little Rock Zoo. He was transferred to the Oregon Zoo the following year, and he and Tilly have been playful visitor favorites ever since. Because both adult otters were born in the wild, they are considered genetically important for the breeding otter population in North American zoos.
Once threatened by fur trappers, North American river otters are now considered rare throughout most of the U.S. due to habitat destruction and water pollution. They are relatively abundant in healthy river systems of the Pacific Northwest though, and are frequently observed in local waterways.
