Finally found the Great Horned Owl in the Spicket River Heron Rookery located in Methuen, MA.  A pair of Great Horned Owls have made a nest here for many years.  Made many visit from the middle of February on with no luck in locating the nest for 2016.  Likelyy, but not yet confirmed that the owlets have hatched.  Stay tuned for more!
