Jackie always takes an early Sunday morning walk around the lake. She encountered this critter trying to get in on the bread scraps intended for ducks, swans and turtles. She says: "We see a lot of them in Lake Austin, where they were first brought in to eat the invasive duckweed. (Of course the nutria and the duckweed have both flourished.) Had never seen one on the hike and bike trail before. However, since the UT rowing crew competes each year for the Fighting Nutria award, nutrias must also be commonplace on Lady Bird Lake. And I found another nutria photo on Flickr from the same area of the trail." She found a link fingering nutria in the top 100 invasive species.
