It was very rewarding to see the Pen in the Haven tucking away a tiny newly hatched cygnet. On  the river there were  two Canada Goose families and the school of young Greylags. The lower path was still impassable at the Irish Bridge ( this may need some investigation). The Little Ringed Plover was on its nest while the other bird flew around. Warblers were fairly scarce and there was not a sign of the Swifts or the Cuckoo. SC/AE
