Mongolia - Khurkh Bird Ringing Station

The trip to Mongolia was a long drawn out affair. A trip to Worcester to share a car to London with an overnight stay at the Hilton Hotel near Heathrow. The next morning was an early 3.5hr flight to Moscow and then a couple of hrs later the connecting 7.5hr flight to Ulaanbaatar the capital of Mongolia. We arrived early morning (+7hrs difference to GMT) dropped off our luggage in the hotel and spent most of the day killing time. The next morning we thought we would start our final 400km taxi ride to the ringing station, but it didn't work out like that. We were asked to go to a meeting with the Director Nyambayar Batbayer of the Wildlife Science and Conservation Centre www.wscc.org.mn who was very interested in out visit and also gave us an overview of all the projects that were being carried out in Mongolia. As it turned out a valuable insight of the work being carried our by the  WSCC. We eventually got on our way and at midnight we arrived at the Khurkh Bird Ringing Station after a 9hr taxi journey.


The next morning after a lie in we got ourselves organised, familiarised our selves with the Yurt, ringing station and all the net rides. Later that day I took a couple of pictures of the area from the top of one of the surrounding hills. The picture above shows the Yurt and is looking north.


This picture is looking south and we were literally living with birds. It was so quiet, literally no noise other than bird sound. You can see from the pictures we were really remote and in the valley the river and scrub trees is where we had the net rides. I've never seen such blue skies.


The Yurt was our home for the length of our visit.

Because of the 3 days it took to get there and a similar number to get home we only had 10 days ringing. The highest number of birds caught in one day was 437 but an average of 165 birds a day was an unexpected good result. From the list there are 15 bird species I've seen or ringed before and 37 new birds. I have to say the Magpies and Rook looked bigger and weighed more than UK birds.


There is a High Flyer set up at KBRS which caught us some nice birds including this Eurasian Nightjar just as it was getting light. You will see from this and other photographs that holding the birds for the camera often involves wing opening.


Thick Billed Warblers are large unstreaked Reed Warblers. They are a migratory warbler which breed in East Asia and winter in South Asia. In the hand they feel very large indeed.


Pallas's Grasshopper Warbler look very similar to our UK Grasshopper Warbler. The supercilium of the Pallas's GW are more prominent and the ground colour is slightly more reddish than the Olive colour of the UK bird. One other i/d are the tips of the tail feathers which are pale creamy grey coloured.


The Lanceolated Warbler is very similar to the UK Grasshopper Warbler, the streaks of the neck and underparts are more heavily marked than both UK Grasshopper and Pallas's warblers and the underparts are sometimes slightly more grey coloured as well. Finally the size of the Lanceolated Warbler is much smaller than the other two.



Red-flanked Bluetail is a wide ranging bird. It is a migrant breeding in mixed coniferous forest in north Asia and northern Europe and winters in south eastern Asia. Occasionally there are sighting in the UK, Titchwell Marsh in Norfolk had a couple of sightings last year. The bird above is a female.


Dusky Warbler


Radde's Warbler

Apparently separating Radde's and Dusky Warblers in the field during Autumn and approaching Winter can be difficult and are the most misidentified species on the British list. There is so much information about this, I have this link to the Internet for those who would like to read more about it. http://home.clara.net/ammodytes/randdw.html We were lucky having Batmunkh around and tapping into his knowledge if we were not sure about something. But, when you read about it, should we have taken these bird i/d's for granted. I think so because birds in the hand for identification are very different than those in the bush because key features can be seen clearly and compared with each other. Also Batmunkh has handled lots of these birds before and is experienced in identifying birds that could be difficult.



Two-barred Warbler a medium sized leaf warbler having a very long yellowish white supercilium, only 29 caught in 2017. You can just make out the two bars on the wing, not the best picture showing you this.



The Brown Shrike was caught in large numbers before we arrived, most birds had migrated passing through the Ringing Station so we only managed 3 new and 2 recaptures. As with all Shrikes they are stunning birds with attitude.


Olive Backed Pipit up until 2013 was on the BBRC species list. In 2012 there was an influx of 50 birds which meant it met with the criteria for removal from the rarities list.


Siberian Rubythroat were the most common bird we ringed, 578 birds in total. They really are stunning, breeding in mixed forests of Siberia, wintering in Thailand, India, Indonesia and Bangladesh.


Siberian Stonechat female. They are brown above and on the head, they have an indistinct pale supercilium and have chestnut buff underparts. There are 6 recognised subspecies.

We had some great birds and in all I had 37 new species. However the most challenging birds for me were the Buntings, only ever ringing Little Buntings abroad before. When you get your eye in they become easier to identify but are they male, female or a juvenile bird. The first few days there was a great deal of referencing from books and help from the vast knowledge of Batmunkh the co-coordinator of the ringing station.


Chinese Bush Warbler is a wide ranging bird. It is found in China, India, Laos, Mongolia, Myanmar, Nepal, Russia, Thailand and Vietnam. Although relatively common just the one bird was caught and ringed.


Arctic warblers are rather strong-billed, slim but are a highly active Phylloscopus as in many small birds. It has a very large range breeding in north Eurasia, north Asia and Alaska and wintering in south east Asia The western birds flying anything up to 13,000km


This White's Thrush was a surprise. Batmunkh the coordinator of the Ringing Station thought the migrating thrushes would not pass through until the week after we left. It is a large powerful bird breeding to the west of the Ural mountains in Russia and wintering in south east Asia. It was sadly the only one we had. 3 were caught is 2017 and this was the first for this year.


Like many Redstarts, Daurian Redstarts are strongly sexually dimorphic.We caught both males and females. The male in the picture is probably a non breeding bird which tend to have mostly a brownish-grey crown and upper mantle. 


Dark-sided Flycatchers have a large range from the northern India subcontinent, Siberia, western and north-eastern China, Korea to Japan with northern populations wintering in Southern China and southeast Asia. Males and females look alike but juveniles have white spots above, mottled breast and buff-tipped wing coverts.


Pallas's Leaf Warbler are very small warblers with a largish head and short tail. It has greenish upperparts and whitish underparts. It has a yellow rump which is not visible in this picture and yellow double wing bars, central crown stripe and distict supercilium.


Red-billed Chough or Chough a social member of the crow family were fairly common but difficult to catch. There are eight subspecies currently recognised. The UK subspecies is pyrrhocorax and the Mongolian is brachypus.

There a few birds that I have not blogged but the most exciting are here.


Just a couple of pictures from inside the Yurt


The two Mongolian students that came with us. Training was difficult their English was better than our Mongolian. Charlie Sargent front left Stu Brown standing, Colin McShane and finally on the right Paul Ashworth.

There is going to be a follow up blog to this and all birds will be Birds of Prey.

The Teifi Autumn - scarce migrants and re-encounters

Blackcaps show the greatest increase of all Warblers passing through the Teifi scrub in the Autumn.


This adult male may be a site faithful migrant using the Teifi as a stopover refuelling site?
Ringed on 13th September 2015 and re encountered 3 years to the day.
From 1st Sept we have caught 107 new Blackcaps though the weather has prevented several ringing sessions.

We don't see a large number of Willow Warblers pass through in Autumn but we do see an increase in Chiffchaffs, 42 so far this September.

We continue to catch both Reed and Sedge Warblers into the month, we hope to catch some late passage birds this week, some of the Reed Warblers may have fledged only recently.
15 Reed and 11 Sedge Warblers ringed so far this month.



We usually find our Sedge Warblers show the largest weight and fat gain of the Warblers, our highest fat so far though, a juvenile with a fat score of 6.

We will continue at our  Teifi Marsh ringing sites through the Autumn....

Wryneck, Bluethroat, Common Rosefinch, Siberian Chiffchaff, 3 Yellow-browed Warblers, Whinchat and 15 Firecrests have all been caught in Autumn on the Teifi Marsh since 2011

One of Charlie's Siskins ringed last July went to the Isle of Arran, controlled in May 2018


 The Arran Natural History Society report says;-


"The Siskin is a common and abundant breeding bird and passage migrant on Arran during the spring and summer months but it is mostly absent during the autumn and winter.
Returning birds start to reappear at feeders from the beginning of March onwards and local birds may start to breed from the middle of this month.
The majority of birds arrive during April although some may still continue to arrive as late as May. During this period Siskins which are migrating to breeding grounds further north add to the number of birds on Arran.
Birds start to move away from Arran during late summer once the breeding season has ended."



Although the RAS period is over for our Teifi Reed Buntings we intend to monitor the activity at our Mallard site where some birds may roost and we are trying to develop a feeding station to encourage them. We have colour-ringed c200 now.

We will try and increase our effort monitoring Pipits on the estuary too. We have ringed both passage and local Rock Pipits, this bird caught last December - we ringed in Oct 2010 !!


With a tail as below and other interesting differences to local birds, where are the migrants from..?
This was one of several birds showing "littorallis"  features.



Andrew and Alison (independently) are off to ring in Gibraltar in the coming weeks and Charlie having just returned from an amazing ringing trip to Mongolia is writing a post as I write.....

Recoveries - - Home and Away

Our 1st Grasshopper Warbler recovery, an adult ringed on 28th April 2018 at Charlie's Fygyn Common site near Brechfa Forest in Carmarthenshire was re-encountered on Squire's Down, Gillingham, in Dorset on the 30th August 2018


9 Grasshopper Warblers have been ringed on Fygyn Common this year compared to none across the Teifi Marsh sites and just 1 at Goodwick Moor.



Back in January / February 2012 we made a 3 week ringing trip to Uganda. We captured 3 species of Nightjar including just one Long-tailed Nightjar

Two days ago on the 9th September Malcolm Wilson posted..

 "Went out for a dazzle with the torch and net, only got one bird, but what a bird! Long-tailed Nightjar that we ringed in January 2012!!
Almost got a Water Thick-knee, but there was a hippo standing just behind it and my net wasn’t big enough..!"




We don't have a photo of the bird when it was originally ringed but this is a blog post about the day it was caught and location. Some Plain Nightjars were ringed that night too.
Uganda 2012, Long-tailed Nightjar

I am back ringing with Malcolm in Uganda in November....... what recaptures and new data awaits us.


Back to nearer home, Jenny one of our trainees joined Wendy and I on Skokholm for the weekend, a short 3 night trip with the ringing of young Manx Shearwaters the priority...


 Of course a bit of migrant ringing too, with this Wryneck being the highlight...


Andrew and Alison, two of our other trainees couldn't make the Skokholm trip due to participating in the joint BTO /  Gower Ringing Group training course - -some highlights soon. Looking forward to highlights from Charlie too, out ringing in Mongolia as I write.
We are introducing Alison to lamping on the Teifi tonight, this juvenile Bar-tailed Godwit the highlight amongst the Dunlin and Ringed Plover caught last night.
