August - Highest numbers since 2015

August gave a magnificent total of 1,513 new birds of 32 species; the highest since 1,590 in 2015.

The top four species now (and in 2015) were 628 Blackcap (417), 208 Whitethroat (241), 150 Chiffchaff (123) and 123 Garden Warbler (179).

Among the less-frequent warblers were 21 Willow Warbler (33), 18 Lesser Whitethroat (22) and 4 Sedge Warbler (22). This follows the national trend for Willow Warblers where numbers are falling in the south of England; whereas the fall in Sedge Warbler, while may be impacted by habitat degradation, requires further study to understand.

Highlights this month were 4 Tree Pipit (Stanwellmoor and Wraysbury) and a Redstart at Wraysbury.

Recoveries included a Common Tern we colour-ringed at Bedfont Lakes in July 2016, sighted, this month, at 138km northwards at Rutland Water.
