Saturday 24th July 2021 - 08:00 to 09:30 The hot spell had broken during the night. It had just stopped raining by the time I set off. It was very humid and close. There were swarms of midges under the trees. Perhaps the insects were attracting the fish because there were lots of large fish cruising at the surface of the lake and jumping. A Grey Heron had returned. The different age groups of Canada Geese now all look almost like their parents. For a while there was only one Great Crested Grebe . But another flew in later and they displayed. Two Egyptian Geese were together. As I walked back up the meadow two Greylag Geese flew into the lake. A full list of birds seen is given in the Bird Table .
