I'm looking for information on Common Terns breeding inland in Maine. Palmer (1949) mentions small colonies in Somerset, Franklin, Piscataquis, Washington and Aroostook counties. MDIFW's 2006 "Island Nesting Tern" species assessment,
https://www1.maine.gov/ifw/pdfs/species_planning/birds/islandnestingterns/ternassessment06.pdf, lists about two dozen colonies with irregular counts, mostly from the 80s and 90s. These are in Penosbcot, Piscataquis, Hancock, Washington and Aroostook counties.
If anyone has info on the current status of any of these (numbers of breeding pairs, colonies established or abandoned), I'd appreciate a PM.
Many thanks, and good birding,
--Charles
