146760 a new boy in the band

We would like to welcome 146760 to the Welsh Cuckoo team.


 The new boy to the Cuckoo team was caught and tagged at Tregaron on Friday 12th June, by BTO’s  Chris Hewson and Mid Wales ringer Tony Cross. When he was caught he was aged as an 2nd summer male and was a very healthy weight of 125 gms



146760 has already begun his migration is currently crossing France and was on the last data update mid-way across France heading towards Montpellier. 



Will he be the first of the welsh tagged birds to take the more direct westerly route, or will be go east via Italy

David the surviving welsh Cuckoo from the class of 2012 is still in the hills south of Tregaron, and still in the area he was originally caught and tagged.


146760 is a bit of a mouthful and he has been given a nick name by BTO staff until he can be officially named. A quick read of Tony's blog will tell his temporary name. 

For more details on 146760 and the other Cuckoos go to hereon the BTO website

Best BBS view in Wales

This morning I took advantage of a break from the wet and windy spell we have had for the past few weeks and went and did my upland BBS square.  Being an upland square and with the seemingly wet late spring I was more than happy to do it later rather than sooner. Now some of these upland squares may not have the sheer volume of birds found on some of the lowland ones but they do make up for it with the odd rather special species and some fantastic scenery.

Now we all carry a camera whether it be a proper one or a phone, so this morning at the beginning of section 8 I took the below shot with my phone.  10 mins either side and it would have been in bright sunshine.

Now I guess that all other BBS volunteers in Wales have similar spectacular views from their squares. So if you have a shot that shows your square and Wales off to it’s best advantage send them in and I’ll put them on the blog. Simple rules all photos must be of or taken from a BBS square in Wales.

The best 5 will be exhibited at the joint WOS conference in November where the audience will be asked to nominate their favorite. I have not sorted a prize yet but I will by them.

North Wales Twite Project

The project has for some years been colour ringing Twite in the Snowdonia breeding grounds and at the wintering grounds on the Dee estuary and various other localities along the North Wales coast.


The results are beginning to indicate that our small relic breeding population migrate eastwards during the autumn and winter on the Dee.  Larger numbers of birds join them, from the Pennine breeding population and further afield. Some of the Pennine birds continue east and winter on the Norfolk coast. In the second year of the project it was suspected that a Nant Ffrancon bird has been seen in the company of some Pennines birds at Titchwell, however the ring combination seen was not sufficient for a 100% identification. This last winter a bird ringed in Nant Ffrancon in April was seen in a Twite flock on the Norfolk coast.


In 2010 a small flock of Twite were present on Pensarn beach one of which had a BTO metal ring. This flock was caught and the ringed bird was found to be from near Lochinver in north-western Scotland. In December 2014 another one of this flock was recaught at Askham, Cumbria.  The small flock which appeared at Cemlyn last autumn also contained a ringed bird. When she was eventually caught she was found to be from the 15 miles south of the original Pensarn Scottish bird.  


For the past two winters we have been very lucky to have Richard Beckett join the Twite team, and Richard has spent many hours recording ring combinations and the comings and goings of the Deeside birds.  This winter a reasonable number of Twite have been feeding regularly at Deeside Naturalist Society reserve, and with their continued permission a further 68 have been colour ringed. Also caught have been a number of birds originally ringed at the Mull of Kintyre. The Mull of Kintyre have a small breeding population but also has a marked passage of autumn birds passing south and reasonable numbers have been ringed there.

We are initially proposing that the coastal wintering birds here in North Wales may well be birds from the north west of Scotland, with our Welsh birds from Snowdonia venturing eastwards and mixing with Pennine birds on the Dee, some of which will continue eastwards with their new mates.

Due to Richards’s diligence last year we knew when the Deeside birds began their spring dispersal and a few weeks later the first of the Nant Ffrancon birds were back in the Ogwen valley. From Richards’s recent observations the flock at Deeside has now begun to disperse. Over the next few weeks the critically low Welsh breeding population will be making their way along the North Wales coast back to Ogwen. Can I ask all North Wales Birders to be aware of this and keep an eye and an ear open for them on passage? We have about two and a half weeks and it would be very interesting if we could plot some of their traditional staging points along the coast.

Thanks and happy hunting.

Please report any sightings to kelvin.jones@bto.org.


The North Wales Twite Project is a collaborative project between, Kelvin Jones, Ian Spence, Richard Beckett, RSPB Cymru,BTO Cymru, National Trust, Snowdonia National Park, Deeside Naturalists Society, North Wales Wildlife Trust, and Flintshire Council

GBW and ringing working hand in hand.



Trevor and Chris Bashford of Dolgellau are possibly the most fortunate Garden Birdwatchers in Wales. As previously reported they regularly have Hawfinches in their garden and have over the past few years read and photographed numerous colour ringed individuals, including a bird from the Forest of Dean last year. 


This year things are going even better with the 100th colour ringed bird being recorded to date, and to quote Trevor, "there seem to be as many unringed birds coming as well"



Now where’s the phone number of that Estate Agent…………………………

Need for Speed

At 15:30 on 3rd December 2014 a Starling was caught and ringed on Bardsey. At 19:00 that evening and 37km away in a roost of over 100,000 Starlings at Afonwen farm near Criccieth the same Starling was caught again by Phil Belman. Phil has been ringing Starlings at this roost site for a number of years and has generated number of interesting records of eastern European birds.

The previous August Dave Hill ringed a Swallow at 12:40 on the 8th at Rhiw on the tip of the peninsula, which was later caught that evening coming in to a roost on Bardsey.

The Swallow was not quite as quick as the Starling. Any other ringers out there with "Speedy" controls?
