Wendover WTW - 26th August 2017 - CES#12

The final session was conducted on 26th August on another beautiful, calm morning.  A slightly below average catch of 30, with Blackbird and Blackcap again the dominant species.

2017 comes in at 8th place of 10 CES years for Total Captures and Total Individual birds trapped but probably the most significant measure is the low number (153) of adult birds this year – 9th lowest of 10.   The 2017 productivity (1st Years/ Adults) of 1.78 was the 5th highest in 10 years and pushed 2017 up into 6th place for the total number of 1st Year birds trapped.

Blackbirds and Blackcaps had reasonable years but most other species were low in comparison.  We have only  trapped 1 Garden Warbler since 2011 and Whitethroat and Lesser Whitethroat numbers were disappointing.

A small squadron of armour plated Dor Beetles (probably Geotrupes stercorarius, see below) were trapped in the 1st round and all except one were released unharmed.  The obligatory Willow Warbler in passage turned up mid-morning avoiding our first ever blank for this species in a CES season (range 1-4).
