We're Knot flagging!

Last year we started two new colour-ringed projects putting leg-flags on Knot and Turnstone. The Turnstone ringing has yet to yield many resightings but the Knot flagging is already proving very rewarding. Here is an update of re-sightings so far.


The Knot flagging project is being done in collaboration with Jim Wilson of the International Wader Study Group and Peter Knight and Rose Maciewicz of Leeds University. Since the scheme began, a total of 70 Knot have been leg-flagged at Ynyslas and, of these, 14 have been re-sighted away from Ynyslas, several on multiple occasions. This is a huge improvement on the results obtained by BTO metal ringing alone where we have previously had just two recoveries from over 350 knot ringed.

To date most of the recoveries have come from the UK but have also included birds re-sighted in Ireland, France, Belgium and Portugal.

The Portuguese re-sighting is very significant as its location would indicate that the bird was of the race Calidris canutus canutus from Siberia which winters in West Africa. This race has very few (if any) confirmed records for Wales (although it must surely be present quite frequently on autumn passage?).

A Great Spot (for Woodpeckers)

Posts on the blog have tailed off a bit in recent years as most of what we do is part of long-term projects, so can become a bit repetitive! Anyway, life has really changed now and anything we manage to do is a complete breath of fresh air (often literally!).
 
One thing I, like many other ringers, have been managing to do in lock-down, in line with guidance from BTO HQ, is ring in the garden. Normally I confine this to when the Siskins, Goldfinches and Redpolls are passing through on spring passage as I'm not massively keen on catching shed loads of local Blue Tits. This year though, bring on the Blue Tits! 

There has been a surprising result to the increased garden netting in that, amazingly, this morning I managed to catch the 30th different Great Spotted Woodpecker on my garden feeders since April 2020 - where on earth are they all coming from?

Sadly, the really old one I caught just over 12 months ago, that was just a few months shy of the current British longevity record for the species, hasn't been one of them.

There are some nights when woodcock ringing is just hard work. Last night aided by Bethyn Thomas and his Dad we saw 38 woodcock, but I could only catch 3. This was because it was very calm and the ground was frosty making a stealthy approach impossible. However there was a reward for our effort and kms walked, one of the three birds caught was a retrap of a woodcock I caught as a juvenile on the very same field eight years ago. This is my oldest retrap to date after catching 2400 woodcock over 12 years. This bird has made 17 migrations across of the North Sea. With an average migration of around 2000 km this individual has probably flown around 35,000 km in its life. I retrapped this bird in the autumn of 2012 and again in Jan 2014, but have not encountered it since. At time like this I dream how amazing it would be if woodcock could talk.

Egrets return

I have recently received reports (and photographs) of two of our colour-ringed Little Egrets. Both birds were ringed on the same day (25th June 2012) over 8 years ago. The first (White T, Yellow A) photographed on Anglesey by Toby Carter has been reported about 10 times over the years all from Malltraeth Marsh at a maximum distance from the ringing site near Bangor of 19.5 kms.

The second bird (White T, Yellow V) photographed at Llansteffan, Carmarthenshire by Mark Carter has only been reported twice previously but amazingly both time were at Playa Blanca, Lanzarote, Canary Islands. The first report was on 8th January 2014 and then again on 15th March 2020. At 2,824 kms, this is one of the longest movements ever recorded for a BTO-ringed Little Egret and mirrors an earlier movement of one of our Bangor-ringed birds to Tenerife. It would be amazing to know if this second bird has been making annual migrations down to the same wintering location on the Canaries (a round trip of over 5,000kms) or whether it suddenly decided to return after 8 years living the ex pat life (which seems highly unlikely!).

Sweet SA

Last night was the first of the next set of high tides for ringing at Ynyslas. As the winds were light and conditions were right I decided to forgo wader dazzling in favour of mist-netting terns. On the last set of tides the estuary was brim-full of Sandwich Terns, Kittiwakes and a raft of other species but the winds were far too high to attempt any netting and unfortunately terns aren't really catchable by dazzling. Sod's law, conditions were now perfect but it was ominously quite on the tern front with nearly all having moved on! Still an opportunity to net terns is never missed even if there isn't much about. With assistance from Stephen Edwards and Gareth and Roy Richardson we set the usual 4 x 60ft wader nets on the point and waited. High tide was a bit early, such that there was no catching on the rising tide as it was too light and the nets were too visible. It did allow us to watch a juvenile Peregrine persistently terrorising the Dunlin (and seemingly inflicting needless damage as we caught four Dunlin with large rips in the skin of their breasts or sides). 

Needless to say I was relieved when we eventually caught our first few terns (Sandwich and Common) along with a few Dunlin, Knot and a Turnstone. The Knot and Turnstone were particularly welcome as it enabled us to kick-start two new colour-marking projects using leg-flags on both species. 




We catch a reasonable number of both species annually but in the past have had very few returns from just BTO metal rings. Hopefully the leg-flags will enable birdwatchers to help us collect additional information and greatly increase the data on movements etc.

Just as we were finishing processing the last few birds Stephen returns from a net round with the exciting news of a foreign-ringed Common Tern. "Wow, that's nice" I say. The reply was "yes, and its a South African ring!" 

My reply is, not surprising to some, unrepeatable!!

We can CU

People call them "unprecedented times", I cannot possibly say what I call them!!

This year's planned Curlew work, along with so much else, has been shelved, just a small piece of the resulting worldwide data gap in long-term monitoring projects that we will never fill. It is, admittedly, a much smaller sacrifice than some have made and was necessary to help save lives but is a real and present pain in the proverbial all the same.

One small saving grace, for us anyway, is that whilst maintaining all rules on social distancing and not putting anyone at increased risk we have just managed to install Curlew Cam on another nest so that people bored with playing Fortnite or watching old re-runs of TV shows that weren't that great first time round can now fill their waking hours watching a Curlew sat motionless on a nest hoping to catch the once every few hours change-over!




Female curlew on Curlew Country's Curlew Cam 2020


This year's camera is on a nest where both adults have previous.

The male (YELLOW BI) was ringed at Dolydd Hafren on 6th August 2015. Unusually he is known to have nested for two years at a nearby territory (about 2km distant) before moving to the current territory near Church Stoke, Powys, where this is his third nesting attempt in three years (all these last three nests were fenced by Curlew Country and all produced hatched chicks. We cannot be 100% sure but we think at least one or two of the resulting chicks fledged successfully). This male is a bit of an A-lister in the Curlew world having starred in an award-winning film by Billy Clapham called Keeper of the Call and appeared on Springwatch in 2019. He is known to winter at Devoran in Cornwall where Mark Grantham has reported seeing him every winter since he was ringed.

The female (YELLOW ID) was also ringed at Dolydd Hafren on 27th March 2017. She is also known to have nested at another territory (some 10km distant) but is not known to have successfully hatched or reared young. She is a new pairing for this male who nested with an unringed bird last year. We do not know where she winters - yet!

The link for the live video feed will be available for the duration of the incubation and can be viewed on Curlew Country's website at

Hopefully things will have eased by the end of the breeding season otherwise the male might not be allowed back to Cornwall this winter!

The welcome return of KFC

No, not a news item about the slackening of Covid-19 restrictions in the takeaway industry.

Thuens Kruger, an avid Sandwich Tern colour-ring reader in South Africa, has just sent me details of Sandwich Tern KFC ringed as a juvenile on autumn passage at Ynyslas in 2016 (shown below) see  https://midwalesringers.blogspot.com/2016/08/a-chicken-sandwich.html




After a 3 year absence it was re-sighted at Eersterivier mouth, Macassar, South Africa on 7th Jan 2020 and 12th Feb 2020 and then again at Greenways, Strand, South Africa on 14th Feb 2020.


Neither photo is his best work but both certainly good enough and absolutely no doubt about the ring inscription, he also managed repeat sightings of KAL and KNB too. Really good to hear KFC is still going - waiting on news of its namesake now!

What a Twite!


One of the 8 Twite ringed at Ynyslas on 26th November 2018 - the first ever in Ceredigion

On 26th November 2018, at one of our regular ringing sites next to Ynyslas NNR, I caught my first ever Twite in over 35 years ringing there. In fact I caught my first ever 8 Twite! One of our then trainees, Ed O'Connor, had found the small flock, the largest seen in Ceredigion for a good many years, a week or two earlier. At my request he had pre-baited the site for a few days whilst we waited for some calmer weather for netting. On the off chance I had asked Kelvin Jones if he would mind sending me a few of his North Wales Twite colour-ring combinations in case we were successful. In a stroke of sheer fortune Kelvin was down in Mid Wales from his more usual North Wales haunts that very evening and I arranged to meet him on his way home to pick some up - hardly expecting they would actually be needed. The following morning we set a couple of 40ft single shelf mist-nets amongst the weed seeds and waited. A few Reed Buntings, Linnets and Chaffinches later Ed saw the small flock fly in off the saltmarsh and land immediately in front of the nets right by the sound lure. A casual saunter towards the nets was all that was needed to push the whole flock straight into the single shelf.

This morning, in what is the best lock-down lightener I had for a good few weeks, I received an email from Kelvin to say that one of them had just been photographed on the Isle of Skye, 575 km NNW! What an amazing result and a clear example of the added benefits of colour-rings.

Not well Choughed!


In September we had a report that two of our colour-ringed Choughs had been re-sighted near Settle in the Yorkshire Dales the first Choughs sighted in Yorkshire for 25 years! The birds were siblings from a brood ringed on North Anglesey in June 2019. Although they were siblings, they were a male and female and could possibly have bred in Yorkshire if they had survived to two years old or more, re-colonising an area that they used to inhabit but haven't bred in for well over 100 years. Unfortunately that isn't going to happen as the young male has just been found dead (no obvious cause). A very sad end indeed.

Baby come back



In 2016 and 2017 we had a brief spell working with the Powys Moorland Partnership monitoring their small Lapwing and Curlew breeding population. The above Curlew chick is the only one we ever managed to colour-ring there. It was ringed on 4th July 2017 near Ireland Moor by Jacques and myself after an epic stint trying to located it from a car some distance off. The main problem was it was highly mobile and every time we spotted it by the time we could run to where it was seen it had bunked off through a dense cover of bracken and hidden. Anyway patience and perseverance finally delivered and three years on we get the rewards of all the effort as it has just been re-sighted (and photographed) at Llangorse Lake by Mark Waldron.


Judging by the bill length it is almost certainly a female and she is likely heading inland to the very hills she was reared in to hopefully try and rear chicks of her own for the first time. Fingers crossed she succeeds, we need all the young Curlews we can get.
