Dave Dawson’s natural history notes for 22nd August 2016:-
Canada Geese, at 110 birds, were seen in high numbers for August, again suggesting no effect of the various attempted control methods. The other two species of goose also continue to be found in high numbers; many Greylags move out by August, so the 30 birds were a high count; conversely, Egyptian Geese breed later and tend to peak this month and the 65 birds was a record number for August. Coots, also at 65 birds, were in larger numbers than usual in August and the other waterweed eater, the Mute Swan, remains in high numbers: 40 birds. Some waterweed was washed up against the dam: Horned Pondweed, Rigid Hornwort and Common Duckweed, but there was no great growth of waterweed, so perhaps Coots and swans are preventing that. Two Gadwall were a first for August, thus continuing the recent increase. Similarly, the 14 Jackdaws were a record number for August. Woodpigeon numbers continue to increase, with the 90 birds being on a par with other recent years as the highest August counts. Pied Wagtails tend to move through at this time of year and the three birds seen was an average number for August. The two Stock Doves singing in Horse Close Wood confirmed the recent increase in this species. Fewer wild flowers are to be seen in the heat of summer, but the brook was an exception with Great Hairy Willowherb and Water Mint both in flower. The hedgerow running north from the stadium had both species of honeysuckle in flower, providing a comparison of the native one with the Japanese species. There was a good crop of acorns, but the majority was affected by the Knopper Gall. A white-flowered cyclamen was in flower beside the path in the middle of the wood. Elderberries were ripening. The tube line embankment had much Buddleia in flower, but few butterflies in evidence.
