Nature Sightings

Welcome to Nature Sightings. Here, we post nature sightings that have been reported to us throughout the Sudbury, Assabet and Concord Rivers Valley.  You'll also find photos from remote wildlife cameras here.  Learn more about our Camera In The Woods project and motion-sensing wildlife cameras.  Also learn about how SVT has helped to monitor wildlife passages beneath route 2 in Concord, and view photos from the project.

If you would like to receive weekly e-mails summarizing the latest additions to Nature Sightings, subscribe to our free e-list.  This is a good way to make sure you never miss a new entry, especially for Camera in the Woods photos, which often come in later than other photos and don't appear on top of the list below.  If you have an interesting sighting, picture or video you would like to share, e-mail Dan Stimson
