Whimbrel records building slowly

Today I received an email from José Velhote informing me of a sighting of one of our colour-ringed Whimbrels at Murtosa, Ria-de-Aveiro, Portugal (see photo above). This is the first sighting of a West Wales colour-ringed ringed Whimbrel in Portugal and follows on rapidly from a record of a colour-ringed bird from Pembrokeshire recently photographed in the Gambia (surprisingly the first record of a BTO-ringed Whimbrel in Gambia)

The bird in question was ringed at Llanon on 3rd May 2010 and was resighted on 1st May 2016.

North or South, that is the question!

Have recently received this photo from Andy Davis of a colour-ringed Kestrel at Little Neston on the Dee Estuary taken on 28th November 2016. Apparently it has been mobbing Short-eared Owls and stealing their catches.

Thanks to Andy for the record and allowing us to use the photo.

I assumed this was probably one of the few birds we colour-ringed in North Wales but having just looked it up was surprised to see it was a bird we ringed as a chick on 26th June 2016 in one of Chris Griffith's nest boxes high in the hills above Caersws, 85 kms from where it is now. The behaviour should have been a clue to its origins! It is one of the great fascinations of bird-ringing as to why one Kestrel from North Wales goes to Northern Spain for the winter whilst another moves north to winter on the Wirral! If it is still there at Christmas I'll have to nip over before dinner and say hi!

H'owls that!

Prince Edward Point Lighthouse at dawn,
 a scene which greeted me every morning 

With University finished and needing to spread my wings, I decided to volunteer for the autumn (fall) at Prince Edward Point Bird Observatory (PEPtBO) from late September until the end of October. Prince Edward County is located on the north eastern shore of Lake Ontario, about 2hrs east of Toronto - a whole oceans width away from Mid Wales.

Northern Saw-whet Owl, one of 715 caught
 in October

Although a relatively small bird observatory, due to its location right on the tip of a peninsular, it processes a huge number of birds in the fall. The operation is smoothly run by master bander Dave Okines and two fall banding assistants (one of which was me), and a brilliant group of volunteers. The first thing I learnt was some lingo: rings are bands and ringing is banding...luckily with Dave being an expat from Britain, skull ossification was kept to a minimum, with moult and feather wear being used to age birds instead.

The real draw to the station was to witness the fall migration of Northern Saw-whet owls, a small species which breeds in the boreal forest in the north of Canada and migrates as far south as North Carolina in the US. The owl banding was broken down into two separate periods: the standard 4 hour period carried out by myself and the other assistant, then a non-standard period which was carried out until morning by David if the weather and the wind direction was favourable. 10 owl nets were opened each evening around an audio lure which attracted the owls into the area.

Barred Owl, innocent looking but will quite
happily feed on Saw-whets if given the chance.

It certainly didn't disappoint. In total 715 Saw-whets were banded during October (an astonishing number), with 167 caught in one night alone, 93 of which were during the standard 4 hour period. Each bird was banded and biometrics and a moult card taken for both wings on birds exhibiting any moult before they were released to continue on their migration. Moult was often obvious, although it could be checked using a UV light with new feathers showing up pink from the presence of the chemical porphyrin. This eventually wears off over time, allowing a pattern to be seen between new and old..

Not quite a nightjar, an Eastern Whip-Poor-Will

It wasn't just Saw-whet Owls which were caught: 22 Barred Owls, 5 Long-Eared Owls and a single Eastern Screech Owl were caught during my stay. The owl nets also caught a couple 

American Woodcock, half the size of the 
European Woodcock I'm used to ringing

of species I was really hoping to see, but wasn't sure I actually would. An Eastern Whip-poor-Will was caught

whilst showing a visiting owl bander from the US the setup one afternoon. It helped demonstrate how quickly the nets could be opened and closed. The second  species was an American Woodcock which graced the nets early one morning - a very unusual fall record.

Two tiny male Kinglet species, Golden Crowned Kinglet
 & Ruby Crowned Kinglet.

Migration monitoring also took place in the cedar woods each morning. This used a mixture of 38mm mist nets and larger 100mm hawk nets, along with a Jay Trap and 6 ground traps. These methods caught a wide variety of species during my stay, which ranged from the tiny Golden-crowned Kinglet to the somewhat larger Red-tailed Hawk!

Sparrow lineup: Lincoln's Sparrow, Slate coloured Junco,
Swamp Sparrow, juv White-Crowned Sparrow

With my very limited knowledge of North American birds it was a steep learning curve, but I soon got used to it and it wasn't long before I could identify and age the wide variety of fall warblers, flycatchers and sparrows which regularly appeared in the nets (they even seem to cause a lot of confusion to American birders). Other more obvious species were also caught such as the Blue Jay, a common and charismatic species that is caught in large numbers throughout the fall with 166 being caught in a single morning during peak migration.

Blue Beauty, adult male Sharp-Shinned Hawk

A surprising number of raptors were also caught during my stay, 6 species were caught during the fall. Sharp-Shinned Hawks were the commonest hawk caught, with both females and males banded allowing a range of ages and moult patterns to be seen. 5 Cooper's Hawk were also caught, with all the birds being young birds, a single Merlin, 2 Red-Shouldered Hawks and 4 Red-Tailed Hawks were also caught.

The standout highlight though had to be the juvenile female Northern Goshawk which was caught, a very smart if a little noisy bird to band. It was a brilliant experience, I learnt a lot, saw new ways of setting up nets and heard about some of the more unusual methods of lamping shorebirds and ducks (they use an airboat!). In total I banded and processed 73 species, with a surprising degree of similarity to the species I trained on in Britain. How amazing would it be if one of them ends up in the nets here in Mid-Wales...?

The Northern Goshawk and hairy bander, this is the only real way to show the size of the bird,
an amazingly long tail and this was only a SMALL female...

Colour-ringed Curlew Control

Just had the details of a colour-ringed Curlew I read in a field above Lledrod on 14th June 2016. Amazingly, given the time of year, it was a French-ringed bird!

Winter in Spain

Ever wondered where all the Kestrels are when you are trying to find one for your New Year's Day Bird list? Surprisingly a good number of our British breeding birds move south for winter. We have just been notified of a bird that I ringed as a chick in June 2015 in North Anglesey, that was recaught by ringers at Vitoria-Gasteiz, Aberasturi, Spain on 16th October 2016. Whilst there have been 181 British-ringed Kestrels found in France this is only the 21st to be recovered in Spain. There have even been 4 recovered in Morocco. If a sizeable proportion of our breeding birds are moving south into France and Spain for the winter then the wide scale use of rodenticide poison to control vole plagues in these countries could be one of the reasons we are seeing a decline in our breeding population.

Happily this bird was released alive and well - we will be keeping a keen eye open for it to see if it returns next spring.

Jackpot...

For the last few months I've been working away in Yorkshire, which on one hand has been great for bird watching but also very frustrating that I am so far away from any of our ringing sites. So when there has been any opportunity to go back to Wales, I've gone. Last night was one of those opportunities, so when I had finished work I headed home stopping at some of our winter wader ringing sites en route. With the moon not up until 23:45 I knew I had plenty of time to search the fields. The main species I was searching for was Jack Snipe (so Silvia and myself can continue our study on them), although as usual I'm happy to see/catch most species. I was not disappointed, after searching four of our sites I must have seen at least 30 Jack Snipe quite evenly distributed between the sites. Many of the birds we mixed in with Snipe 'flocks' making them hard to get near, but I did manage to find 10 or so on their own of which I caught 6! All 6 birds were new, which I was a bit surprised by, given that over the past 3 winters we've probably ringed 150+ individuals between the 4 sites. Maybe it's a sign that it's going to be a bumper year for them, fingers crossed.

Several other birds were seen throughout the searching including 50 Golden Plover (3 were trapped), 10 Lapwing, 250 Snipe (2 were trapped), 2 Woodcock (1 was trapped), 6 Fieldfare (2 were trapped) and 2 Skylarks.

Interesting Dunlins?!

Anyone who has been on a big dazzling catch at Ynyslas with me will know that I can be just a bit disparaging about Dunlin (or Sea Dunnocks as I've been known to call them). The BTO have just emailed me a couple of recoveries that put me right on this matter and confirm that, far from being boring, these common and unassuming little waders do put themselves about a bit!

The Dunlin that we caught on 22nd July 2016 with a San Sebastian ring had been ringed on 13th August 2015 at Parque National Marismas del Odiel, Huelva, Spain (1,707 kms due S). Interestingly we have just had a colour-ringed Sandwich Tern recorded from the same place  that was originally ringed at Ynyslas.

Also, a Dunlin ringed at Ynyslas on 24th September 2014 was retrapped by Swedish ringers at Ottenby on 23rd July 2016, 1,387 kms ENE

The two recoveries are shown on the map below with some of our other recent Dunlin recoveries and controls. The green markers show the origin of foreign-ringed birds controlled at Ynyslas whereas the red markers show the recovery site of birds ringed at Ynyslas.

The map is starting to show the great importance of the Dyfi as a migratory stop-off point for birds moving between their northern breeding sites and southerly winter quarters. Our new colour-ringing project will hopefully increase the number of movements we can chart and make far more of the Dunlin we ring 'interesting'.

Nocturnal wader catchers

Last night was the first in the next good set of tides for ringing waders at Ynyslas so I headed down just before high tide. There were a good number of birds present, including at least two Dunlin colour-ringed on the last high tides over a week ago indicating that some birds will hang around a while to fatten-up before presumably moving on. Another colour-ringed bird has already been recorded further south in Cornwall and a Dunlin ringed earlier in the autumn before we started colour-ringing has just been controlled in North Wales.

Last night I managed to colour-ring another 59 Dunlin and had what is probably a record catch for the site of 17 Knot, including a juvenile bird ringed elsewhere. There was added interest in the shape of a Bar-tailed Godwit and a Grey Plover, neither of which are ringed in any number by the group.

I wasn't the only one out catching waders there last night though. Towards the end of the tide a shadowy figure floated low over my head and landed on the sand just in front of me. Two stealthy approaches later (it flew off on the first and landed again a bit further away) and I had yet another Short-eared Owl for the site safely under the net.

The bird was an adult female in wing moult, so almost certainly a local(ish) breeding bird rather than a migrant, but clearly from her weight she was at least as successful at catching waders as me!

A little bit of magic!

On Sunday, Jaques was keen to have one last ringing session before he heads off to Prince Edward Island, Canada on a 2 month ringing trip. We started with a little bit of dazzling just south of Aberystwyth where we managed to catch a Bar-tailed Godwit, an Oystercatcher and a single Dunlin which, apart from a few Ringed Plovers, was pretty much all we saw.

This time of the year is a good time to tape-lure Meadow Pipits as they commence their autumn migrations. The weather was perfect too with light winds and a little bit of hill fog so at first light we headed into the hills and set up a couple of mist-nets in a 'V' shape and placed the sound lure in the centre. Almost instantly pipits began responding and during the course of the morning a modest but steady 44 were ringed. Most were 1st year birds aged on the moult limit in the greater coverts although there were a couple of adults included, both showing the last traces of moult on their inner secondaries.

The activity of the pipits attracted the curiosity of a couple of Stonechats, one of which was also caught and ringed.

After browsing the Ringers' Facebook page for a while on Jacques phone, and trying to decide if social media is really all that 'sociable', I glance up. "What's that in the net?" I ask whilst simultaneously bundling myself out the door as fast as I can manage.

This stunning adult male Merlin was obviously hunting pipits too (but luckily no pipits were hurt during the taking of this bird)! A classic example of how ringing is full of lovely little surprises!

A very unusual ringing site!!

On Wednesday evening Jacques and I were heading down to Borth to try for a few more Swallows and then kick start the Group's new Dunlin colour-ringing scheme at Ynyslas later on. Anticipating a long night we thought we better fuel-up beforehand so stopped off at the Acorn Fish and Chip shop in Borth where the great excitement amid the queuing customers was the presence of a small bird fluttering in the dark recesses of the wooden A frames high above the deep-fat fryer, periodically sprinkling the chips with dust and droppings. "We'll sort that for you" I said "we're bird catchers!" A blank expression confirmed that the Oriental women behind the counter had absolutely no idea what I was on about. "No, really we are" adds Jacques - but still no recognition! "Want us to catch it for you?" I try again. "I would" says one of the other waiting diners, so, quick as a flash I run to the car and come back in with an extending hand-net. One deft swipe at full stretch and the bird (which bizarrely for a sea-side town with no trees whatsoever turns out to be a Treecreeper) is safely under the net on the floor of the chippy to rousing applause from the open-mouthed onlookers (well almost)! It was perhaps one of the most pressured and therefore one of most satisfying catches ever, a bit like a scene from Ghostbusters (the old version, obviously!). "Thank you very much" says the Oriental women smiling broadly, "no problem" I say, "Worth free chips that?" I try but unfortunately the blank expression had already returned! Still it prevented said Treecreeper from becoming just another Scottish delicacy!

I wonder if this is the first bird ever caught and ringed in a serving chip shop?!

A record shot of one lucky Treecreeper just prior to being liberated on Borth Bog

In something of an anticlimax the Swallow roost behind Borth produced just 20 new birds, although it is getting on and they will possibly be the last 20 of the year.

In the early hours at Ynyslas though we were soon back on a roll with a catch of 30 Dunlin, 7 Ringed Plover and a Knot. Very respectable given that the tides are low at present and I wasn't really expecting to catch anything other than maybe one or two  Dunlin to try the new colour-rings on. The 30 Dunlin ringed took the total number caught at Ynyslas in 2016 so far to over 1,000! Hopefully a lot more colour-rings will be applied soon so please keep your eyes peeled for Dunlin with a Yellow engraved ring on the right tibia and a plain Orange one on the left. All birds will look identical unless the code is read so also keep a telescope or camera and long-lens handy!!

 The first Dunlin (juvenile) colour-ringed by the group in what is hoped

 will become a major new project over the next few years.

One good tern......

deserves another....

Last night David Tompkins and I had a netting session at Ynyslas to try and colour-ring a few more Sandwich Terns. This set of high tides has been a bit frustrating so far as the wind has ruled out the use of mist-nets and so we have been relying on dazzling, and terns don't dazzle!  Although there have been a few Sandwich Terns around they don't seem to be using the point as a roost and we failed to catch any on this set of tides. We did however catch two Common Terns and two Roseate Terns. These are only the fourth and fifth Roseates to be caught at Ynyslas. The previous three birds had all been ringed in the Republic of Ireland and it is almost certain that the juvenile we caught wearing a ring last night has been too. The adult it was with was unringed, and given the intensive ringing projects in operation in Ireland for this species I bet there aren't that many of them around.

A first for me was the capture of an adult Knot. It is not unusual to catch Knot in small numbers at Ynyslas at this time of year but they are invariably juvenile birds freshly arrived from their breeding grounds.

Over the set of tides we managed to ring a total of 247 Dunlin, 9 Ringed Plover, 6 Knot, 4 Oystercatcher, 2 Turnstone, 1 Greenshank, 1 Redshank, 1 Sanderling, 1 Curlew Sandpiper, 2 Common Terns and 1 Roseate Tern (plus the control juvenile). Many thanks to David, Mark Cutts and Jane for their invaluable assistance.

The nights are drawing out

For the past two and a half months I have been pretty much nocturnal, or crepuscular at least. I am extremely fortunate that much of my paid fieldwork these days is directed towards one of my favourite birds, the Nightjar. These are truly fascinating birds. A friend once called them a bird designed by the Japanese because of all the special features! Massive mirror lens eyes (the Tapetum lucidum), a set of well-developed rictal bristle to direct moths into the extremely large gape, and even a comb on their toe to comb these bristles. Their main feature however is their amazing camouflage and an ability to nest almost completely undetected!! Despite lots of fieldwork, radio-tags, GPS geolocators and thermal imaging cameras I have managed to find a grand total of just 6 nests this year. The poor weather has been a major hinderance with activity levels well below normal but amazingly all 6 nests produced 2 chicks each. So far this year we have ringed a total of 49 Nightjars, including 12 chicks and retrapped at least a dozen birds ringed in previous years.

A Nightjar chick, capable of flight but still being fed by the adults.

At several of the breeding territories the first real proof that the birds were even attempting to nest was the appearance of fledged young, although, to be fair, these could have moved in from outside the study area. GPS tags have been fitted to 6 males this year and three of these have already been recovered. Each tag has shown a great amount of movement around the forest with the birds visiting a great range of clear-fells over the course of a few nights. One tag recorded over 1,200 GPS quality locations showing that the bird was covering most of the forest, far from the rigid territoriality that would be expected and helpful! A great example of the fact that the more information we gather the more questions it poses.

A juvenile Nightjar

Along with the tagging and nest recording, this year we have been collaborating in a large study looking at the genetics of Nightjars being conducted by a Hasselt University in Belgium. Birds caught for ringing and chicks in the nest have been buccal swabbed under licence from the BTO and these will be compared with birds caught elsewhere in this country and in Europe.

Buccal swabs air-drying before being sent off for DNA analysis at Hasselt University, Belgium

Much of the monitoring work being undertaken aims to investigate any possible effects of onshore wind farm development on Nightjar populations including the avoidance of active nests during the construction phase

The past fortnight or so has seen some lovely warm nights, great weather for Nightjarring, and it has allowed us to trap and ring a few juveniles and target a few of the birds still wearing GPS tags in the hope that we may still get the odd one back. Thankfully though, the Nightjar season (and the massive amount of driving it entails) is drawing to an end and there is a brief chance to get some quality sleep before the Golden Plovers and Woodcock return.

Messing about on the river

This time of year is always full of different ringing opportunities with so little time to do everything you'd like (sleep!) and even less time therefore to blog. As a result, and because I couldn't do a better job myself anyway, please find a link to one prepared earlier by my old mate Steve Parr following a recent weekend visit.

Goosander and Common Sandpiper ringing

A Chicken Sandwich?

Last night saw the first successful Sandwich Tern catch of the year with 4 new birds colour-ringed - 2 adults and 2 juveniles. The second bird of the night was a great sponsorship opportunity missed, especially given the trade myself, Jacques and David Tompkins have given the Oswestry branch on our way to and from Nightjarring this summer!!

Also caught were 20 Dunlin, 3 Sanderling and 2 Ringed Plover. Bigger things to come on the next few sets of high tides hopefully but a great start to the autumn. On the previous set of tides  Jane and I had an unsuccessful attempt to catch Sandwich Terns but did manage a modest catch of 10 Dunlin, greatly improved by the fact that the first one out of the net was wearing a San Sebastian ring!! Had me going for a while as I thought that might have been in South America!!

Reports have been trickling in recently of colour-ringed Sandwich Terns caught at Ynyslas in previous seasons including KDB back from Namibia (seen and photographed at Dawlish Warren along with 3 other Ynyslas-ringed birds KAL, KAH and a BTO only by Lee Collins), KBB at Rhos Point, Caernarfon (seen and photographed by Rob Sandham) and KBC at Ainsdale on the Mersey (seen and photographed by Peter Kinsella). Many thanks to all for taking the time to report their sightings. All good evidence, if any should be needed, of the benefits of colour-rings over ordinary metal ones.

The grass isn't always greener

Spent the morning catching up on a bit of much-needed paperwork today but was being constantly distracted by a family party of at least six Green Woodpeckers in the field behind the house. Not able to resist the temptation for long I quickly set a net in the garden and played the Green Woodpecker tape. Within a few minutes I had caught three of the 4+ juveniles and an adult had got out of the net too. Not bad in this part of the world where Green Woodpeckers are a bit thin on the ground.

Desperately need to upgrade my iPhone, the camera on this one isn't the best!! Any special offers Apple? A juvenile Green Woodpecker, one of three caught in the garden this morning!

It's a trap......!!!

Last night after struggling with weeks of far from ideal Nightjarring weather the heat was finally turned up and what a difference it made. Lucky mascot Dan Carrington (who has not yet been on an unsuccessful Nightjar session) and I caught an amazing SEVEN different adult birds comprising 6 males and a female.  We also checked on a nest with a point of fledge chick that will hopefully get ringed later today by Mike Shewring. Five of the birds were fitted with radio-tags for subsequent tracking and they were also mouth-swabbed as part of a BTO investigation into Nightjar DNA. As you can see there's not much difficulty in persuading a Nightjar to open its mouth for swabbing.

The only downside to the whole evening was that I somehow managed to let go of  the  first male we caught just after taking him out of the net so he didn't get ringed!  That  is  the  first and last time that's going to happen and a bloody good job it wasn't a trainee that did it.......!!

Wandering Whimbrel

I recently received an email with the photos below attached of Whimbrel D74 feeding in pasture fields at Dokkedal in Denmark on 11th July 2016. This is a great sighting and according to the BTO's online ringing reports it is only the fourth record of a BTO ringed Whimbrel in Denmark. It was originally ringed on spring passage on 30th April 2016 at Llanon, Ceredigion

Additionally, Dolly, one of the two Curlews we satellite-tagged at Dolydd Hafren, that was confirmed nesting on the Forest of Bowland in Lancashire (map shown in the last blog post), has now crossed the Irish Sea and is hanging around the Barrow Estuary near Waterford in Southern Ireland. Sadly Fran, the other bird, has not been heard of since Mid April and I'm afraid the tag has either failed or she is no longer with us.

Curlew catastrophe

During the spring Amanda Perkins, David Tompkins and I have been out talking to farmers and scouring the hills and fields of the Shropshire/Powys border looking for breeding Curlews as part of a 3 year HLF funded project run by the Stiperstones and Corndon Hill Landscape Partnership Scheme. 

Stiperstones and Corndon Hill Curlew recovery project

Building on last year and assisted by an army of volunteer Curlew surveyors from the local Community Wildlife Groups, co-ordinated by Leo Smith, we managed to locate approximately 40 pairs of territorial Curlews. This information then helped guide us to find a total of 21 nests, almost twice as many as in 2015.

Most nests were located in hay or silage fields

 but some were in the more expected semi-improved or rough grassland

Most of these nests had surveillance cameras installed in an attempt to find out what was causing the nests to fail. Of the 21 nests located just three hatched a total of seven chicks and all seven chicks were known (or assumed) to be dead after less than a week. All seven chicks were fitted with small radio-tags whilst still in the nest. Two tags were recovered from under obvious perches indicating avian predation, one was recovered from under a hedge along with the metal leg-ring suggesting mammalian predation and one was the unfortunate victim of agricultural activity. Of the 18 failures at egg stage at least eight were due to foxes and at least three were due to badgers. One nest was trampled by sheep, another was trampled by cows and one nest was deserted, possible due to low and prolonged helicopter activity. The cause of failure at the remaining nests was not ascertained.

It is telling that at all three of the nests that hatched chicks we had installed electric fences, one from early on and two in the second half of incubation. It is our intention to fence far more nests next year in an attempt to increase the number of nests that progress to hatching. 

Three nests were protected by three-strand electric fences 

covering an area no less than 22m x 22m centred on the nest

It was a real ray of light in an otherwise frustrating and gloomy season that the farmers involved were so willing to engage with us in our attempts to monitor nests and to do what they could to help the Curlews succeed and our sincere thanks go to all of them.

Thanks to the agreement of the farmer the small area of un-cut grass in the middle of the field below the tractors held a Curlew nest that successfully hatched two chicks, although unfortunately both were subsequently predated.

To end on a slightly more positive note. During the spring another 40 odd Curlews were colour-ringed at the Montgomeryshire Wildlife Trust's Dolydd Hafren reserve. This brings the total ringed there in the last two years to 62. No fewer than eight of these birds were identified at local breeding sites, a brilliant result and something we hope to improve on in coming years. Two other Curlews, satellite tagged at Dolydd Hafren in March, were also tracked to breeding sites, one near Hay-on-Wye and the other on the Forest of Bowland!

The above map helped local RSPB Conservation advisor Gavin Thomas locate

 the nest of this satellite-tagged female from Dolydd Hafren

It is very pleasing that we still have a Curlew population locally, albeit very reduced, but if these breeding results are widespread, and there is absolutely no reason to suggest otherwise, then we may not have them for much longer. Curlews, being so long-lived, naturally have a low reproductive rate but they still need to get some young away each year!!

An Ospreye!

Well we have just seen the end of Flaming June, or flaming June as I'd prefer to call it! Generally the weather has been dire and not very helpful at all. None-the-less a great deal of ringing has been going on over the past two months and when we get a minute we will update you with a few blog posts. In the meantime here is one that has been expertly crafted by Emyr at the Dyfi Osprey Project to show one of our last ringing events of June, no similar hanging around by those guys!

Dun-in!

May is a good month to catch migrating waders. Most of the Whimbrel we colour-ring are caught in either the last week of April or the first two weeks of May so recently all attention has been on the coast, mostly south of Aberystwyth. On Sunday night however, Paul and Silvia went to Ynyslas on the first of a very good set of tides and managed to ring 49 Dunlin. With Paul reporting over 600 Dunlin present Jacques, Jane and I paid a visit the following night when the tide was slightly later (and therefore it was also a bit darker) and caught an amazing 110 Dunlin, 1 Whimbrel and a Short-eared Owl that was also cashing-in on the wader bonanza.

Interrupted eating an unfortunate Dunlin.

 This bird was aged and sexed as a 5F (i.e. hatched in 2015) based on tail pattern and the colour of the inner web of the outer secondaries and thick streaking on the underside.

By rights this should be a photo of a Dunlin but to be honest I've seen

 quite enough of them for a while!!

The total of 112 birds is the highest number of birds dazzled in a single evening by anyone within the group. With catching that good Jacques and I couldn't resist returning the following evening and managed to boost that record catch even higher to 156 with another 149 Dunlin (plus a couple of retraps), 2 Whimbrel, 1 Sanderling and a Turnstone. In the 30 years I have been ringing at Ynyslas I have never seen anything quite like it, there were  literally thousands of birds present and a good number were actually picked off the sand by hand! It was like walking through a blizzard.  Catching was limited solely by the time it took to bag birds up and the number of bird-bags I had with me. 

With so many birds to ring and process it was a late finish and a real struggle driving home - not good really for getting up early and driving 300 miles to ring Choughs in Cornwall the following day!
