Thankfully activity levels in May picked up after an extremely slow April.

After a short break in Poole (8th – 11th) visiting family and with the windy weather abating a little, I finally got to ring some birds, 3 Blue tit pulli from one of my garden boxes, I had checked the box on the 7th and found a brood of 8, unfortunately the weather had been rather cold, wet and windy over the weekend and by the 12th there was only 3 pulli left.

On the 14th I was over at Woolley Firs (WF) to give support to Carl who was giving a presentation on bird ringing and our involvement at WF to the members of the Wildlife Trust, this proved to be very popular and provoked plenty of interest and questions.

On the 16th I was back at WF again checking boxes with Carl, Paul & Roger, initial findings suggest this season’s productivity is below last year.

On the 17th this female barn owl was found to be incubating a clutch of 5 eggs in a box at another one of our Berkshire locations.

The following day (18th) I was on my own patch checking boxes in the woods on Langley Bottom Farm (LBF).

I was happy to see the 3 ringed garden box birds fledge on the 19th, a relief really knowing how difficult it had been for the hardworking parents during the horrible weather.

The pulli ringing ramped up on the 23rd on LBF with 29 birds ringed from 3 boxes, one box with 12 pulli turned out to be the largest brood of the year in the wood.

Wraysbury CES 3 was held on the 28th, again there was a worry the wind would cause issue and we would have a weather affected session, however the predicted gusts didn’t reach the suggested speeds and we did manage to complete the session. 42 birds processed with a 21 new/21 retrap split.

The final birding activity on the 28th saw me once again in the woods on LBF with a further 28 pulli ringed from 4 boxes. There is just one brood left to ring.

So all-in-all an excellent month. Next up, more owl boxes to check and a trip to the Isle of May.

Saturday 31st January

I spent the day with Carl & Paul at various locations west of Windsor: at Fifield; Holyport; and Touchen End bolting Barn owl and Little owl bird boxes to trees. Whilst at our last location we were asked by a neighbour if they could add further boxes to their land, they have a Barn owl box at the moment which was occupied by a Barn owl this year and a Kestrel last. A further visit is planned.

with another early visit to Woolley Firs looking to catch more Redwing, a 0600 hrs start saw 4 of us in the fields setting up in the dark. The weather forecasters haven’t exactly been on top form of recent so we took a slight chance that the wind wouldn’t be as forecast. However it was and this had a big impact on our catch with only 10 birds caught, but at least we did catch a 5 Redwing! Also caught; Yellowhammer, Jay, Great tit, Blue tit and Long-tailed tit. However, I missed most of the action though due to the quick onset of a headache shortly after set-up which had me in the car popping pills (headache remedy pills!).  I was in two minds whether to go home but thought it best to let my pounding head subside first. I didn’t really want to leave because we had plans to ring Tawny and Barn owls later in the day.

The wind continued to cause issue, most of all making the nets very visible to the birds, the decision was made to set-down around 1045 hrs after a couple of rounds without birds. I was able to help with take down as my headache was finally easing, which was a relief as this meant I would be ok to ring the owls.

We left site and headed for a cafe for a spot to eat before heading over to Bisham wood and the owls, a very tasty full English was consumed which helped banish the remnant of the headache.

Over the past two years a few members of our ringing group have been taking part in the reinstating of an owl project in some of the woods in and around Berkshire. Initially we had to establish the locations of the boxes and gps them, once this was done we had to clear the boxes out, removing multiple layers of nests or old squirrel dreys, then remove the boxes we considered to be surplus to requirements and relocate in new locations. Many of the boxes have been in place for 10 years so there was also plenty of repairs to do.

So our first port of call for the owls was Bisham Wood,  a couple of Tawny owls had been seen roosting in one of the boxes the previous week and we had high hopes they would still be using the same box, it turned out that they had moved residence but fortunately only along to the next box. We carefully retrieved the Owls and checked to see if they had been ringed before, they both hadn’t so we ringed them. A thorough examination of the wing feathers had us determine they were both adult bird with both having 3 generations of feathers, a wing length was recorded and a weight taken and a few photographs of the open wing for the records before we released them back into the wood.

The second location, Little Marlow, where we hoped to ring a couple of Barn owls, was just a short 10 minute trip from Bisham wood, a private family house with a Barn owl box in a tree in the garden. A camera was installed in this box so we where able to confirm the owls where in residence with a quick phone call before setting off. This box had had a breeding pair in the summer who had managed to fledge 5 from a brood of 6, which is a very good outcome for Barn owls, the young birds had all been ringed before they’d fledged. Now the box was being used as a roost possibly by the breeding pair. Again we carefully retrieved the birds and ringed them. These two did indeed turn out to be an adult male and female.

I took advantage of the sunny day today and managed to get onto the farm and into Little Snells wood to place the first 5 bird boxes. I intend to have 20 boxes in the wood in total consisting of 12 Blue tit/ Great tit, 5 open fronted and a Barn owl, Tawny owl and Kestrel.
