The good news is that all the Great Tits that we ringed (26) fledged from the boxes. The Pied Flycatchers (4) all fledged as well, and 99 of the 108 Blue Tits also fledged successfully. Hopefully, I'll be able to retrap some of the Tits over the winter, and who knows, perhaps see one of the Pied Flycatchers next year!
After checking the nestboxes I had a walk around the top and middle reservoirs to see what else was about. Great-crested Grebes are doing well this year, with 2 pairs both with chicks, a brood of 4 and 1. There were good numbers of Mallard about (50+), 1 juvenile Moorhen, 2 Coot broods (3 and 4), 5 Mandarin Duck broods (7, 3, 2, 4 and 2), and best of all, a Tufted Duck with 6 very young ducklings. This is the second brood of Tufted Ducks this year, following a brood of 9 back in June (see here).

There weren't many insects/butterflies seen, as it was pretty grey and overcast, with several showers, but 3 Ringlets and 5 Meadow Browns did manage to flutter about!
