Sunday update...


Yesterday's (Saturday) ringing at Linford Lakes was very productive with 58 new birds and 7 re-traps of 18 species. Warblers dominated, all of which were new and included some juveniles. They included a Cetti's Warbler, eight Blackcaps, eight Whitethroats, seven Reed Warblers, two Garden Warblers and three Chiffchaffs. The catch also included six gorgeous speckled juvenile Robins, three Treecreepers, a Song Thrush and two Bullfinches.

Kenny returned in the evening and just about survived the mosquitoes to catch five Sand Martins. One was a juvenile and the other four were adults, one of which was first ringed there last year.

Kenny's sustained efforts at this site are paying off with some excellent ringing recoveries. We have been notified of a controlled Garden Warbler which was first ringed as a juvenile at Icklesham in East Sussex on 16th August 2011 and re-trapped at Linford Lakes on 7th May this year. A period of 1726 days elapsed between the two dates and of course this small bundle of flesh and feathers has now successfully migrated and wintered well south of the Sahara on five occasions. Just amazing!

Today (Sunday) and Eric Graham was out again at Thrapston Gravel Pits spending most of his time on the Titchmarsh Reserve. Morning sunshine brought out a host of insects including plenty of dragonflies and butterflies. A drake Red-crested Pochard was the birding highlight.

Visit Five of the Constant Effort Site ringing programme at Pitsford Reservoir this morning yielded just 39 birds of 15 species, an all-time low and to a certain extent quite a contrast to Linford Lakes.
The catch included five Chiffchaffs, five Blackcaps, two Garden Warblers, a Willow Warbler, a Reed Warbler. a Song Thrush and three Bullfinches. Preliminary analysis suggests that the numbers are depleted due to a lack of on-territory adult warblers and juveniles of common resident birds.

Presumed breeding Spotted Flycatchers have been vocal at Hanging Houghton, Lamport Hall and Orton during the last couple of days and this morning some agricultural grassland at the latter site was home to a colony of Small Heath butterflies, Azure Blue Damselflies and a Mother Shipton moth.
