Four or five years ago, two dozen or more herons began nesting on the edge of Libby Hill trails. Beaver activity on the section of Thayer brook has created a beaver pond that is over 4 feet deep in sections and hundreds of dead trees (snags) that act as excellent nesting locations for herons.
Herons usually nest on off shore islands in Maine, so having an inland colony is a real gem for our wildlife lovers!
Finding the colony
Park at the trail head across from the GNG Middle School. Take the Lynx (Blue) to Harold Libbey (Red) then Outback (Yellow) trails. After crossing the brook in about 200 feet you come to an trail junction, go left for 1/2 mile until you see the open marsh and nests. Work your way round the marsh off trail. Total distance is about 3 miles, allow 2 hours or more for your trip.
