Thanks for the kind words JTF, most appreciated.
I've spoken to the people at Wye Marsh and am sending them hard copy pictures as they don't have email accounts big enough to handle the size of the photos. Each photo will have the date and location of each of the sightings too, in order to help them find out where their birds are heading to.
Along with the 2 in the photograph above, I also saw a family of untagged Trumpeters with 4 juveniles shown below and also 4 Mute Swans sitting on the edge of a very crowded ice flow.
