Calvert BBOWT Lake; Yesterday morning gulls settled at North end by reeds when they all erupted into air, ducks and Grebes swam out from reeds and suspected a Bittern could be about. Did Bittern watch tonight but got something totally unexpected. Gulls again settled near reeds and flew up in panic. I Quickly scanned for Bittern in flight, and got a big pair of brown wings over the reedbed but they were attached to a female/imm MARSH HARRIER!!!
It did three low circuits over the reedbed areas then lost to view in far left corner; it either dropped into reeds to roost or carried on North. it was mobbed by a Carrion Crow and a Red Kite. This was at 1500 hours. Got some chronic record shots on compact camera with no zoom. This our 1st ever Winter record of one here. Also female Goldeneye/ 141 G.B.B gulls (Tim Watts)
