Marsworth CES 11 - Willow Warblers passing through.

Marsworth
Nets: 540' 05:45 - 11:45am
Ringers: LL, CMS, GK

A beautiful calm and sunny late summer morning. Claire and I had been down during the week and tried some nets in a different part of the site and caught 40 birds including 7 willow warblers so we knew they were passing though. Even so we were pleased to catch another 13 on Sunday including 2 adults (11 in the CES nets). Other highlights were three juvenile Garden Warblers and 2 new 3J Cetti's Warblers. In contrast to Pete's abundant Blackbirds at Wendover, we still did not catch any. We heard Green Woodpecker, Great Spotted Woodpecker, Jay, Mistle Thrush and Hobby calling in the trees and a large juvenile Sparrowhawk landed briefly on the branch above our heads. Shame none of them went in the nets!
A total of 64 CES birds is above average (ave 48) and brings our total for 11 sessions to 720 against an average of 625. Considering that after the first 6 sessions we were still 7% below average it shows how much the number of young chiffchaff, wrens and now willow warblers have boosted our numbers this year.
