Excitement is Building as the Heron Observation Network Enters Year 15!

Our 2022 results show a slight increase in the number of nesting pairs of great blue herons in Maine, the first time since 2015. We are gearing up for our 15th year of monitoring heron colonies with the help of so many AMAZING volunteers.
