540’ CES 12
Report by Johne
Bank Holiday Monday began warm with a slight south westerly breeze and it soon became quite hot.
An early round of over 70 birds quickly subsided to a more sedate pace apart from a brief flurry in net 2 around 9am.
A respectable total of 103 new birds and 24 retraps, one of which might be a control Chiffchaff. We shall see.
3 more Willow warblers and 3 Garden warblers plus 38 Blackcaps and 20 Chiffchaffs.
Star birds were 2 juvenile Marsh tits.
A moth trap had been run overnight again, this time in long grass and scrub away from the reedbed. Moth captures were rather disappointing as the table at the end of this report shows. It could be partly explained by the presence of a hornet in the trap which might have encouraged some moths to find a way out.
Looking at the CES figures for this year shows an average catch of 75.33 birds. An improvement on 2016 average of 61 per visit.
This years average is in fact close to the mean for 2005 until 2017 of 75.56. I have not looked in detail at the CES data yet but I suspect that 2017 will prove to be at least much better than last year.
