Last couple of hours of daylight spent at Amwell – morning sledging at Therfield Heath where a Red Kite was seen. Amwell mostly frozen with the gulls out on the ice. Unfortunately they were just slightly too distant to read the rings:
Great Black-backed Gull – first winter with dark blue or black ring on left leg and BTO on right. Apparently of Norwegian origin.
Lesser Black-backed Gulls – adult and second winter with red rings on left leg and BTO ring on right.
Herring Gull – adult with blue and yellow ring on left leg and BTO ring on right.
Two Bitterns seen in flight, a female Pintail, and a Little Egret.
