I can hear RWBB in the woodlot across the street. I walked around Cranberry Marsh yesterday and although the perimeter meadow adjacent to the marsh was quiet there were blackbirds calling along the reeds of the southern margin. The southern half of the marsh was mostly wet mud while the northern portion was still pond-like, although perhaps not very deep. It would be a great habitat for visiting shorebirds but by the time they arrive, in late-May, everything will probably be all dried up. RWBBs are at least two weeks earlier than usual.
