Nutria (Myocastor coypus) on Mar 23, 2018

Submitter does not have a specimen

Description of specimen

There are 4-5 nutria living in this park. I have more photos if you are interested. I have also submitted this image to the Oregon iMapInvasives project on iNaturalist. They are definitely nutria and not muskrats or beavers. They are accustomed to people and will hang out very near the boardwalk.

Commentary

Thank you for your report, and apologies for the very delayed response! Nutria are, unfortunately, pretty common in the Willamette Valley. Due to their abundance in our area, they are usually not removed from parks because there are plenty of nearby nutria to come back in. You can read more about nutria in Oregon at https://www.dfw.state.or.us/wildlife/living_with/nutria.asp
Thanks again for your report, and also for participating in the iMapInvasives iNaturalist project! All these sites are incorporated into our statewide iMapInvasives dataset for use by managers, researchers, and the public.
Regards,
Lindsey

Resources

There is a lot of good information about nutria in Oregon on the Oregon Department of Fish and Wildlife's Living With Wildlife site.

Location

All around Sunset park. I see them from the boardwalk almost every time I visit, which is frequent.
