Facts and Figures from 25 Years of CES

Monday, August 28th 2017

Tony started to number crunch and look at the data.

Just two basic statistics jump out: as near as I can get it we have put out and taken down ca 200Km of net.

Averaged out we have put in 732m of net every CES day this year!

Putting up one of the nets

And doing net rounds - measured very conservatively - we have walked half way round the world at least!

Doing a net round

On CES alone, removing any duplication and in all weathers, we have caught 48,021 birds averaging 1920 birds a year. This equates to 160 birds for every single outing.

We have put on £5210 worth of rings, have processed 120,872 birds in and around Catterick Garrison, and have processed 222,745 birds as a group with probably 2000+ still waiting to be entered. At Foxglove alone we have ringed 60,071 new birds, an average of 2403 new birds every year.

We received comments from other bird ringers.  This from Jack who rings on Salisbury Plain.

What an amazing achievement and some unbelievable time and effort by all. That takes some serious team effort and special commitment. Just wanted to say well done.

Kind Regards


From Roger Dickey

Brilliant effort. Well done to all who contributed in reaching this milestone.

And from Robin, one of our ringers

And to add a bit off weight behind it , since starting ringing I've put on two stone, thanks for all the cakes and sausage rolls ! Great to be part of it.

And incidentally, after removing the duplicates today, we were 4 birds short of the best ever CES 12 total which was 307 in 2011!

And finally from Tony

My very sincere thanks go to every single one of you who has helped create this remarkable achievement. Here I include the whole ringing group and all our volunteers and supporters, those that have strimmed and mowed our net rides in the rain.  The data is a major component in the song bird studies being carried out by the BTO and it is a credit to you all. I am deeply grateful to every one of you - this really is a major milestone

Well done and congratulations to everyone.
