I participated in my two local CBC's this year, Southern York County and Biddeford/Kennebunkport. Looking at their results together, there was clear confirmation of the continued northward expansion into Maine (and/or increased wintering over) of several species.

Both counts had record highs for Tufted Titmouse (252 and 253), Carolina Wren (21 and 13), and Red-bellied Woodpecker (47 and 48).

Eastern Bluebird with 110 in S York didn't reach its previous high of 131, but Bidd/Kport blew away its record of 150 with a new high of 249.
