Nutria (Myocastor coypus) on Feb 20, 2013

Submitter does not have a specimen

Description of specimen

It was grooming itself outside of a beaver lodge. Approximately 11:30 am, February 23. This is not the first time that I have seen nutria on this lake. I believe that I first saw two nutria leaving the lodge. I thought that they might be beaver because there is evidence of much beaver activity.

Commentary

I have video, too.

Patrick, hhank you for submitting the report. Nutria are are now common in urban wetlands around the region, partly due to the fact they are often fed by humans.

It is important to realize that nutria are rodents and potential reservoirs for a variety of diseases that can be transferred to other species, including humans in some cases.

The nutria page on the Center for Lakes and Reservoirs website at http://www.clr.pdx.edu/projects/ans/nutria.php contains more information on nutria impacts if you are interested. Trevor Sheffel's contact information can also be found on this site if you have questions or would like further information.
