Four visits were made to Wilstone during September, two were calm and pleasant and two were annoyingly breezy.

Nevertheless, we had a very good number of Blackcaps, Chiffchaffs and Reed Warblers. The month's total of newly ringed Blackcaps surpassed the annual totals of the two previous years. So far this year the total is 452 new and 16 retraps, last year it was 296 and in 2016 it was 216.

Why so many Blackcaps? The Elder trees are not particularly bountiful this Autumn and having taken out the mature trees between net ride four and five, I was expecting less rather than more captures in this first year. So, there just were more birds passing through at an opportune time, I guess.

Three Spotted Flycatchers and a male Sparrowhawk were probably the birds of the month but four Kingfishers together in the same net took some beating.
