Broadwater GP - 25 August 2015

We (DKL, MRB, BC & Margaret) managed to get a session in before the heavy showers forecast for the afternoon began. We had seven nets up and the wind was lower than expected in the early morning. It seemed relatively slow with ones and twos coming in after rounds, except for two decent rounds as roving flocks connected with the nets set along the path. We took all but two nets down as some very heavy clouds came over, with a few spots of rain, at about 11am, not wanting to be in the position of having a lot of birds awaiting extraction if the rain were to start early.

We finished on 48 birds with Chiffchaff as the leading species. A Willow Warbler with a fat score of four was consistent with a bird well into its preparations to move on, but there has been no repeat of the bumper captures of Phylloscopus warblers in late August (and early September) of last year. If large numbers do pass through, the likelihood is that there will be no ringers available to catch them due to commitments abroad.

Wraysbury GP - 19 August 2015

There were no takers to join us for a morning at Wraysbury so we had to process all 94 birds ourselves. Today saw the numbers of Blackcaps caught edging ahead of Whitethroats that had been most numerous just two days ago. The number of retraps compared to new birds ringed had also reduced, indicating that there has been another influx of migrants.

A single Reed Bunting was the first ringed for a few weeks, but the most unexpected feature of the morning, was the ease with which we managed to capture Goldfinches.

Broadwater GP - 18 August 2015

A forecast for wind made Broadwater the perfect option today. We began setting up from 7am, erected the usual eight nets, and made an addition to the normal mist nets by siting one in the access road where birds are frequently seen to cross towards a residential garden.

3JP Blue Tit

It was a slowish start that continued the same way and never really picked up much. There were a few tits from the access road, some Goldcrests (leading species) and a couple of Treecreepers.

This little guy wasn't keen to go when taken back where it was caught.

We still aren't getting the large flocks at the moment,but this could be linked to the presence of some young Sparrowhawks that have recently fledged, but are still being fed by the adults and are extremely vocal.

Stanwell Moor - 17 August 2015

After an early start at Wraysbury, CL & DKL went on to Stanwell for some evening ringing with the chance of hirundines. Our efforts netted 45 birds, with Greenshank, Common Sandpiper, Hobby, Buzzard and Little Egret seen also with two Cetti's Warblers and a Water Rail heard.

The start was unusual with a flock of Chiffchaff almost lining up to leap into one of the reedbed nets.
We caught another Meadow Pipit from the ground trap and Sedge Warblers, for the second session running,  featured strongly. We then started to catch Reed Warblers and these included a couple of birds with D- prefix rings, one of our own and another that had been controlled last year.

There were few hirundines around but three caught of the seven present was a bonus, considering the affect of the planes taking off and drowning out the audio-lure.

Wraysbury GP - 17 August 2015

Today we were joined by MRB & Margaret, visitors to the group, to monitor C6. It seemed less busy than some recent sessions, but a total of 78 birds were still processed before we took down as the wind got up. Leading species is now Whitethroat.

Chobham Common - 16 August 2015

For the first time this summer we made arrangements and finally got to the common. We were hoping to catch migrants as we have seen large numbers of Willow Warblers working through this area at about this time of year, but as it was, only managed two. It would have been a very slow morning if we'd not caught quite a few birds from a tit flock early on, and that, at least also brought some Coat Tits.

As the morning progressed we caught a couple of young Dartford Warblers, even 'though the area is not what we would consider as prime habitat for the species.

 Dartford Warblers hatched this year. The first was considerably less advanced in its post juvenile moult than the second.

 The double where the first Dartford was caught - mainly scattered trees and long grass.

There were lots of Graylings around, though this one settled on a 
dead tree trunk, rather than the ground.

Just for good measure we finished off with a young Stonechat.

Stanwell Moor GP - 15 August 2015

This site has been somewhat neglected this year, what with the movements of HGVs creating a disturbance, the lake being drained to dampen dust on the access road, the ever expanding heap of bricks and the utter reluctance of hirundines to venture anywhere near the reed bed. So, we decided that we would try a weekend morning session when vehicle movements should be less intensive than on week days. We were fortunate that the correct runway was in use, that is to say we were not subject to planes taking off, every 90 seconds, directly over the lake.

We arrived just after 6am, put up six nets around the lake and also gave our newly constructed (courtesy of MRB) Mipit ground trap its first outing.

The mist nets were soon catching and we were pleased with the numbers of Chiffchaff caught. We also got a few adult Acros.
