Geese?

D.W had a flock of grey geese flying south west over the village at about 9am. I then had a family group of 7 grey geese flying north east over the reservoir at 1 p.m. I did not think they were Greylag and the head seemed large in relation to a short neck. The juv. Scaup was again present this morning, but could not be found when I watched the gull roost at 3.30 pm. 23 Common gulls and 1 L.B.B. amongst the Black headeds.
