CES Visit 12 26/08/2017

32 birds were caught on our final visit. It was clear to see that the majority of our breeding migrant birds had left our site or maybe we didn't see or hear any apart from Chiffchaff and Blackcap. Common Whitethroat hadn't been caught since visit 10 and the only other migrant apart from Chiff on Visit 11 was a Willow Warbler....so it's confirmation this year again that Chiff's are the first to arrive and last to depart on our site at least.

So the CES season now on our site now comes to a close.....we look forward to next season and hopefully many of our birds will return to breed again.

I'd like to take this opportunity to thank everyone from Lothian Ringing Group who kindly gave up their spare time to come along and help out during the 12 CES visit's.

They also went on to do another 2 extra CES visits to gauge what was still hanging around after the 12 visits were completed. Again like our site only Chiffchaff & Blackcap remained....they were also rewarded with another Kingfisher!
Well worth an extra visit

CES Visit 11 13/08/2017

Visit 11 was a little disappointing... only 28 birds caught compared to last year where 42 birds were caught on the same visit.

Although the majority we were catching were still mainly juveniles there was that feeling that a lot of our birds that we had caught on previous sessions were maybe departed. We did catch a Chiffchaff that we had first ringed last year as a juvenile, we discovered that it had now come back as a breeding female to the site where it had been born....always amazing to have these birds return, makes it all worth while for the effort that we all put in!


                       We managed to catch 4 Bullfinch to-day, 3 Juvenile and an adult female.

Although we were disappointed with the overall number of birds we caught, we were rewarded with our first Yellowhammer caught during a CES visit and the first caught on our site since winter ringing in November 2013.

Sand Martin Ringing

After gaining permission from East Lothian Council Ranger service to study one of the Sand Martin colony's on their reserve, there seemed no time like the present to carry out a first visit to the colony at the end of June this year.

Nick Aitken who has been with ELC ranger service for over 13 years was very interested in coming along to see how the birds were caught and biometrics taken at the time of ringing these birds....off course Nick knew all about Bird Ringing as LRG had been involved in helping out with previous ringing demonstrations in conjunction with ELC & BTO at RSPB's Big nature festival which had been held near this site for 2 years prior.

I had let Nick know that if he was definitely interested in coming along it would be a fairly early start, setting up the nets in the dark prior to the Sand Martins coming out of their nest holes before sunrise.

We both duly arrived on site and set 1x18m and 1x12m along the ash-bank prior to sun rise around 03:15hrs....the wind was slowly picking up, the site is situated where the westerly wind was making it obvious that we wouldn't have the nets set up too long....in fact after the first net round I decided that we should take the net down as it had picked up that much in the space of an hour.

However, Nick wasn't to be too disappointed at losing half his nights sleep as we managed to catch 24 birds on the first and only net round of the morning.

It was a real learning curve for Nick especially as he had been monitoring this particular site for some years to gauge how many were nesting here, to then have them in the hand and so close up ageing, sexing, wing length & weight prior to releasing them within a matter of minutes of this happening was he said a real privilege.

We're hopeful that this colony will hold enough birds for it to become part of a BTO project -"Retrapping Adults for Survival (RAS) scheme which is a national standardised ringing programme within the BTO Ringing Scheme that has been running since 1999. Ringers aim to catch or re-sight at least 50 adult birds of a single species in a study area during the breeding season. The study area is well defined and the ringer is aiming to record the vast majority of the adults". © British Trust for Ornithology.

I'd like to take this opportunity to thank East Lothian Council for allowing LRG to carry out this study. Particular thanks to Nick Aitken & Neil Clark.

CES Visit 10 06/08/2017





The early morning alarm is very much a struggle on a Sunday morning.... even more so when you know the rest of the family are still tucked up in bed. So what makes it special for us involved with CES ringing? Yes, it is of course the sight that the rest of the family won't see too often....a beautiful sunrise.

I suppose maybe arriving on site for 05:00hrs is a longer lay in than some ringers participating in this project have, there are more than 140 sites over the UK which also have teams that set their alarms early, making sure they also waken up at an unearthly hour to complete these visits.

It's not just the sunrise that entices us to get out early, it is also the uncertainty of what will be caught on this visit that lures us out....is a rarity going to grace our nets to-day....we certainly weren't disappointed....it was something that has become much more of a rarity on our site....Greenfinch! This was the first one we have caught on site since a winter ringing session in Feb 2015....the last time we caught one during a CES visit was June 2012.... forgive us for getting excited when we seen this one in our nets today.

The first Greenfinch caught on one of our
Constant effort visit's since June 2012

It's hard to imagine that Chiffchaff, Willow Warbler, Blackcap & Common Whitethroat are much more abundant on our site, the habitat is more than adequate to cater for breeding Greenfinch. This is one of the main reason's why we all look forward to the alarm going off in the small hours of a Sunday morning, we can then try to understand what's happening when monitoring our bird populations through the Constant Effort Scheme, this way we can hopefully take appropriate action where it's required.

LRG's other CES visit 10 was much more productive to-day....with the re-trap Blackbird coming back to the site after initially being ringed in 2014. It's also very pleasing to see that Willow Warblers and Blackcap numbers were up to-day compared to previous visits!
