Yesterday Adrienne Stratford, Jack Slattery and I replaced or installed a couple of new Chough nest-boxes in North Ceredigion. The first site, between Borth and Aberystwyth, which was used successfully in 2022 (rearing a brood of 4 chicks) was considerably the worse for wear with the top completely collapsed in. Not surprising though as I originally installed this with Mick Green back in the early 1990s! If it lasts anywhere near as long as the first one it certainly won't be me replacing it next time!

Danish Nightjar details
I have just received the original ringing details of the Danish-ringed Nightjar that I controlled in North Wales. It was ringed as a juvenile on 21st August 2021 at Glæde, Thisted, Viborg, Denmark.
Given the age at ringing and the date of ringing there is still some uncertainty about the provenance of this individual. In many species of bird juveniles often make exploratory movements away from their natal area before heading south on migration. This bird could have been a bird reared in Denmark that has subsequently nested in Wales or perhaps more likely it could also have been a British-bred bird that dispersed north (or even got blown north whilst on migration) before correcting itself and heading south to its winter quarters.
Normally we would be left not knowing which scenario was correct but in this instance we may have an ace in the hole that could give us more clarity. Over that past few seasons, as assistance to George Day (a PhD student at York University working on European Nightjar breeding systems) I have DNA sampled a large proportion of the birds breeding and reared on the wind farm monitoring site at Clocaenog. I also managed to collect a shed feather from the Danish-ringed bird. It may therefore be possible to compare the DNA profiles and see how likely it is that the bird was from the local Welsh population or whether it was sufficiently different to imply a more distant origin.

A nocturnal surprise!

European Curlew Connections
Well we might have ill-advisedly severed our close connections to Europe but our Curlews seem not to have done the same.
Three recent sightings have highlighted, once again, the vital need for cross-border conservation initiatives when dealing with species such as the Curlew. It is well-known that our breeding population is supplemented each winter by large numbers of birds seeking refuge from colder climes in Scandinavia, Poland, Germany, Russia and elsewhere in Northern Europe. It is less well known that, whilst most just move to southern Britain or Ireland for the winter, some of our breeding birds also move to warmer countries a bit further south.
Yellow FW, a bird that regularly winters at Petit Port, Jersey has now returned for the 5th winter in succession.Yellow ZB a breeding male from the Shropshire part of the Curlew Country area was reported in Northern France in July (see earlier post Curlew là là) and now Yellow XC, an adult female ringed at a newly created wader scrape in the Curlew Country area, has been photographed near Santander - no not the one in Welshpool High Street, the one in Northern Spain! According to the BTOs current Online Ringing and Recovery Reports BTO online-ringing-reports this is only the fifth reported record of a British-ringed Curlew in Spain.

Pushing boundaries
Since the formation of the Mid Wales Ringing Group (and the start of the Dunlin colour-ringing project) in 2016 we have individually colour-marked over 6,000 Dunlin. The colour-marking has massively improved the recovery rate of our marked Dunlin and so far we have had over 450 sightings from a wide geographical area. Two recent sightings though have greatly extended the boundary of the area that Ynyslas Dunlin are know to either come from or go to. Olivier Gilg recently informed us of the sighting of LP0, a Dunlin ringed by Paul and Silvia on 23rd August 2020, seen on territory in NE Greenland (where it was being attacked by a breeding Sabine's Gull!).
Of the 450+ sightings submitted so far, foreign movements of Dunlin to or from Ynyslas have included Greenland (3), Iceland (4), Faero Islands (1), Norway (3), Sweden (5), Finland (2), Estonia (1), Denmark (4), Germany (4), Poland (2), Republic of Ireland (23), The Netherlands (5), France (30), Switzerland (1), Spain (62), Portugal (15), Canary Islands (2), Morocco (2), Mauritania (124), Senegal (1) and The Gambia (1)
(NB these totals may contain more than one sighting of the same individual)
So next time you see a flock of Dunlin, and rapidly ignore them in search of something more exciting, take a moment to think that in the summer some of those birds may have spent their time dodging Sabine's Gulls, Arctic foxes and even Polar Bears and may be heading off to spend the winter dodging Black Kites, Jackals and Crocodiles, it's amazing really that there are still so many of them!

New Colour-ring Reporter App
Thanks to the IT skills of Stephen Vickers we now have an automated colour-ring reporter app. If you click the link on the top right of the website you will see the above screen and there you can input your sightings of any of our colour-ringed birds. The app will then generate an immediate output detailing the ringing information and any subsequent re-sightings. I hope you like this exciting new development and that this may encourage a few more birders to submit their colour-ring sightings directly (in return for instant gratification!).

Where do you think you're going?
An email popped into my inbox today with details of a sighting of a young Kestrel, ringed earlier this year in one of Red Liford's nest boxes near Lledrod in Ceredigion. Given the location and the distance of the sighting I was a bit sceptical that the report was correct but, if it was, wanted to post something on the blog. I sent the finder an email to see if they had any photos of the bird and thankfully, not only did they have photos but several (not posted here) confirmed, without any doubt, that the bird in question was one that we had ringed and was not one from another scheme with similar rings. It was photographed (looking very sorry for itself) in heavy rain on Rattray Lighthouse in Aberdeenshire, just over 600km NNE of where it had hatched!
I really hope the bird in question survives and in a way I hope it doesn't attempt the return journey, at least not until we get some better weather next year.

Curlew chick releases
Hopefully some of these birds will return to breed and help keep the iconic bubbling song of the curlew a feature of the Welsh Marches. Please keep yours eyes peeled for colour-rings on any Curlew you may see anywhere and report, it may even be one of those shown in this video!

First and Fortunate 2
Over the last 20 odd years records of Hobby in summer have increased in Ceredigion. Tregaron Bog and Borth Bog have been favoured sites as the birds hunt the plentiful supplies of dragonflies. More random sightings in farmland have hinted at breeding birds becoming established and breeding was confirmed for the first time in the county just a few years ago.
A couple of days back, I was contacted by a friend and ex 'C' ringer of mine to say he had a pair of Hobby nesting not far from his house and did I have a schedule 1 licence to ring them? Well, fortunately, I do, so yesterday, having obtained the landowner's permission Silvia and I went over to check the nest and see if it was safely accessible.
As far as I am aware these are the first two Hobby pulli ever ringed in Ceredigion and they may be only the second and third Hobby ever ringed in the county. We were fortunate enough to catch one "accidentally" on Both Bog a few years ago as it pursued a Cuckoo across the reedbed.
Both chicks were colour-ringed so we look forward to receiving sightings of them in the future, hopefully settling locally and expanding our breeding population of this stunning little falcon.

Curlew là là
On 10th July 2021 Pierre Leon photographed Curlew Yellow ZB on the shore of Plage du Vogue, Guisseny, France. This bird was caught and ringed in the breeding season at one of the Curlew Country breeding territories using a whoosh net and decoy. This is highly significant as it provides yet more confirmation that some of our breeding Curlews winter in, or pass through, France, where, until recently Curlew was still a legal quarry species and where as recently as 2019 there was an intention to set a 'sustainable' harvest limit of 6,000 birds! Thankfully, due to widespread international outcry, the decision was amended and the bag limit was set to zero for the 2019/2020 hunting season. Hopefully, international pressure will continue and those birds from our rapidly declining breeding population that choose to move to France for the winter can do so in relative safety.
Yellow ZB either wintering or staging at Guisseny in northern France in mid-July just over 450 kms from Shropshire where he had attempted (and presumably failed) to breed.
