With juveniles dispersing and adult migrants starting to move, the July total of 837 of 35 species.
This does not reflect the effort put in by teams as some CES sessions gave lower numbers than expected and mowing at Wraysbury reduced the cover and feeding opportunities. Nevertheless, 837 compares well with July in previous years and is the highest since 2011.
The most abundant species was Blackcap on 173 with Whitethroat on 141 and Garden Warbler 109.
Good records were of two Nightjar, two Stonechats, five Dartford Warblers, eight Greenfinch and 14 Linnet. Robins were high at 45 but Wren only mustered nine. Details came in for a Reed Warbler, ringed just north of Basle in Switzerland in 2015 and controlled at Stanwellmoor in 20017.
