An evening walk along the river (now swollen and muddy after overnight rain) produced quite a lot of evidence of the progress of the season. Goldfinch numbers certainly seem to have risen, possibly due to fledged broods being on the wing. A feeding group of ten Woodpigeons included three juveniles. 
Bullfinches seem to be more obvious with four singles seen in the last two days. Chaffinches are still singing, as are Woodpigeons, Blackbirds and Wrens. Tits are mostly invisible with only Blue Tit appearing on my lists by virtue of having a call which I recognise. 
There seems to have been an influx of (? post-breeding) Rooks into the area (I'm fairly sure they don't nest locally). Similarly, about 20 Black-headed Gulls have arrived to exploit the flies over the river (joined by five House Martins and a Swift in the cool, showery weather). Lesser Black-backed Gulls remain in the area and may be increasing in numbers
The Indian Balsam plants along the river banks are just beginning to come into flower and will soon be attracting masses of hoverflies.
