Nutria (Myocastor coypus) on Mar 30, 2009

Submitter does not have a specimen

Description of specimen

Was showing my daughter the ducks on the pond before getting into our car. Saw the Nutria swimming, then climb out of the water. Looked like a Beaver, but with a long thin tail, not a paddle-like tail, so confident of identification.

Commentary

Thank you for submitting the report. Unfortunately, nutria are are now common in urban wetlands around the Portland area, and I have received previous reports from this location.

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. As is the case with many species of wildlife, nutria can become aggressive if they are disturbed; it is important to leave them alone and not feed them.

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. My contact information can also be found on this site if you have questions or would like further information.

Thanks again for your efforts!
