Tour Summary:

Bhutan has for many years been one of those countries that have captured the thoughts and imaginations of numerous world travellers. It’s a country that boasts some incredible wilderness areas including the most pristine remaining Himalayan forests, a very unique and interesting culture, is off the beaten track and, above all else, offers up a mouth-watering selection of quality birds that can be viewed in stunning surroundings. Spring is the ultimate time for a birding tour to this part of the world as birds prepare to breed and are vocally at their peak. This is also the time when visiting birders have the opportunity to view the region’s specialties as they move from their lower wintering areas up to their breeding grounds at higher elevation. Spring also brings about a splurge of colour to the surroundings with flowering Rhododendrons and Magnolias, which often create the perfect recipe for some memorable feeding flocks. Besides Bhutan, we also visited the superb reserves of Kaziranga and Nameri in North East India, and the combination of these sites produced an impressive trip total of 494 species (of which 476 were seen). Legendary birds included Satyr Tragopan, resplendent Himalayan Monal, Blood Pheasant, bizarre Ibisbill, monotypic Wallcreeper, all 7 Wren-Babblers including the extremely localized and rare Long-billed and Bar-winged Wren-Babblers, Sikkim Wedge-billed Babbler, 4 species of parrotbill (including the rare Pale-billed), seldom-seen White-hooded Babbler, impressive Rufous-necked, Great and Wreathed Hornbills, extremely rare White-bellied Heron, much- regarded Beautiful Nuthatch, Slaty-bellied Tesia, Himalayan Cutia, stunning Fire-tailed and Mrs Gould’s Sunbirds, Golden-naped Finch, endangered Greater Adjutant, Swamp Francolin and White- winged Duck, these being just some of the many exciting species that were sighted on this fabulous birding tour!

Our trip began in the capital city of Assam, namely Guwahati, and with everyone and their bags all arriving in good time we managed to get away quickly and strike out for our first birding site, the local dump on the outskirts of town. This is undoubtedly the world’s prime spot to see Greater Adjutant (and quite possibly the strangest way to start a tour), a huge stork, which is under serious threat of extinction. We found around 100 of these large birds, with another 10 or so of the smaller and more widespread Lesser Adjutant also putting in an Greater Adjutant by Markus Lilje appearance. Other birds in this area included Grey- headed Lapwing, Striated Grassbird, Bronze-winged Jacana, Black-breasted Weaver, Citrine Wagtail and Black-tailed Godwit, as well as Great and Pied Mynas and Eastern Cattle Egret sorting through the trash. Soon we were on the road again and heading towards our first destination, the world famous Kaziranga National Park. The park is most renowned for its huge population of Indian Rhinoceros; however, it is also home to an excellent variety birds and other wildlife. During our time at Kaziranga we explored the park by jeep, giving us access to a good diversity of habitat and subsequently some excellent findings on the birding front. Highlights at the numerous waterbodies that are dotted throughout the reserve included good numbers of ducks such as Bar- headed Goose, Common Shelduck, Gadwall and Eurasian Teal, the stately Black-necked and Woolly-necked Storks, Spot-billed Pelican, Pallas’s and Indian Rhinoceros by Markus Lilje Grey-headed Fish Eagles, Northern Lapwing, Pheasant-tailed Jacana and a

Trip Report - RBT Bhutan & Assam extension I 2014 3 single Eurasian Spoonbill. Our explorations of the rest of the reserve’s habitats produced the range- restricted Swamp Francolin, Himalayan and Griffon Vultures, Blossom-headed Parakeet, Green-billed Malkoha, handsome Blue-bearded and Chestnut-headed Bee- eaters, Scarlet Minivet, Ruby-cheeked and Crimson Sunbirds, impressive Great Hornbill, Streak-throated Woodpecker, skulking Chestnut-capped Babbler, Rufous-necked Laughingthrush, Scarlet-backed Flowerpecker and Rosy Pipit. We also enjoyed numerous sightings of the endangered Indian Rhinoceros and other wildlife including Swamp and Hog Deer, impressive Water Buffalo, Asian Elephant, Capped Langur, Bar-headed Goose by Markus Lilje and a small group of Smooth-coated Otter. A huge bonus was scoping a wonderful Tiger from one of the viewing towers! While this animal was very distant and some participants only ever saw the head, it is just with great luck that you ever get to see this magnificent cat in this park! An Elephant ride on the final morning is always an experience, and despite us not finding a Bengal Florican, there were a good few things to report, including Striated Babbler, Bengal Bush Lark, White-tailed Rubythroat and Barred Buttonquail, as well us more good views of the Indian Rhinos that the park is so well known for.

Our second and final birding site on the Assam extension was the fabulous Nameri National Park, which oozed a far more remote feeling than Kaziranga. Here all activities are essentially done on foot, though we did take some time out to explore the bordering river by boat. Nameri is dominated by beautiful broadleaved forests that border the large Jia Bhoreli River and it is this habitat that forms the core of our birding in the reserve. Our afternoon boat trip yielded good views of Black Stork, Small Pratincole, Common Merganser, Great Cormorant, Little Ringed and Kentish Plovers, Great and Indian Stone-curlews and River Lapwing, while walks in the adjacent forests and along the banks of the river produced some fantastic birds. Highlights included the sought-after White-winged Duck, a huge flock of Wreathed Hornbill, Barred Cuckoo-Dove, Orange-breasted, Thick-billed Oriental Hobby by Markus Lilje and Wedge-tailed Green Pigeons, Lesser Coucal, Sand Lark, Dusky and Tickell’s Leaf Warblers, Pin-striped Tit-Babbler, Pale-chinned Blue Flycatcher, Small Niltava and Plain Flowerpecker. The area around our tented camp also produced a few good birds and we enjoyed some nice looks at Plaintive Cuckoo, Slaty-backed Flycatcher, Thick-billed Warbler, Abbott’s Babbler, Brown Hawk-Owl and Scaly Thrush. During a longer walk we found a fruiting tree that produced fantastic views of Orange-headed and Black-breasted Thrush, gorgeous male Siberian Rubythroat and close scope views of the tricky Oriental Common Merganser by Markus Lilje Hobby.

The lengthy drive from Nameri to the Bhutan border was largely unproductive from a birding point of view, besides a large flock of Lesser Whistling Duck as well as the usual roadside species of the area, including Lesser Adjutant, Asian Openbill, Little Cormorant and Indian Pond Heron, to name a few. We then enjoyed a scrumptious lunch and had the interesting borders to cross, including the Indian one, waiting on a big sofa for the passports to get stamped, and the Bhutan one, which effectively allows us to enter into what seemed like a different world. Our arrival at Samdrup Jongkhar was greeted by fair

Trip Report - RBT Bhutan & Assam extension I 2014 4 weather and a delicious tea on the veranda at our guest house for the night. This was a wonderful introduction to a country that immediately hits you in a hugely positive way and in total contrast to neighbouring India. Bhutan is like walking into a sanctuary compared to anything around it, with vast forested valleys leading up to the mighty Himalayan mountain range forming the border with China in the north of the country. We were excited for what lay ahead and what we were hoping to see, now having been joined by the rest of the group who joined those that had done the extension.

The low-lying area around Samdrup Jongkar, where we spent the first night in Bhutan as well as much of the following morning, provided the chance to find a few species that are very restricted in the generally high-lying habitats in the country. Some of the birds we only found in this area or mainly here included Rufescent Prinia, Dark-rumped Swift, White-browed Scimitar Babbler, Asian Fairy-bluebird, Black-backed and Slaty-backed Forktails, the amazing Sultan Tit, White-throated, Ashy and Black-crested Bulbuls and Streaked Spiderhunter. Slaty-backed Forktail by Markus Lilje

After some great morning’s birding we began to slowly make our way up to Morong, our camp for the next 2 nights, which was set at around 1750 m. Without a doubt Bhutan has some of the windiest roads in the world and we had our first taste of this here, driving at a slow pace, which in turn allows for birds to be found from the vehicle throughout the tour – on this section we had Collared Owlet and Long-tailed Sibia in this fashion. Our campsite for the next two nights had the most incredible views of the surrounding forest and it was a great place to start birding Beautiful Nuthatch by Markus Lilje right from our accommodations. During the time we had in this area, exploring the wonderful and extensive broadleaved forest, we picked up many specials including the biggest target: Beautiful Nuthatch, which didn’t even require hard work this time, as a pair of them fed and relaxed on a typically moss-covered branch just 25m away! On this section we also found the regional speciality Rufous-necked Hornbill, which showed a few times, as well as Spot-winged Grosbeak and a good-sized flock of Brown Bullfinch! A few of the many others we spotted in this area, where we got our real introduction into eastern Himalayan forest birding, included the fabulous and always sought-after Himalayan Cutia, Grey-chinned and Short-billed Minivets, Blyth’s Shrike-babbler, Striated Bulbul, Black-faced Warbler, a few different Phylloscopus and Seicercus warblers, including an invasion of Buff-barred Warbler, Golden Babbler, Rusty-fronted Himalayan Cutia by Markus Lilje Barwing, White-naped Yuhina, Red-headed Trogon, Blue-winged Minla, Grey-winged Blackbird, the uncommon Bay Woodpecker, Black-throated Prinia, Yellow- cheeked Tit, Rufous-winged Fulvetta, Silver-eared Mesia, very vocal but often hard to find Large Hawk-Cuckoo, Bhutan, Rufous-necked, Striated, White-crested and Blue-winged Laughingthrushes, the first of many Yellow-breasted Greenfinch and Scarlet Finch.

Our drive from Morong through to Trashigang was a fairly lengthy one, yet it passes through some incredible habitat and we only wished we had the time to get out and bird it all. Our short stops and spotting from the bus were however handsomely rewarded with the undoubted bird of the day – the bizarre Slender-billed Scimitar Babbler, which gave us incredibly close and extensive views. The area

Trip Report - RBT Bhutan & Assam extension I 2014 5 also rewarded our efforts with sightings of the scarce Golden-naped Finch, Dark-rumped Rosefinch, Bar-throated and Red-tailed Minlas and, later, the curious Yellow-rumped Honeyguide, which always seems to be in attendance of large Rock Bee hives. We were also keeping a look-out for the monotypic Wallcreeper, which is often seen scaling sheer rock walls at this altitude early in the spring – we were rewarded with a single bird that showed very well and allowed for some great views. Closer to Trashigang, the forests turn to Chir Pine with a grassy understory that is largely birdless, though we did add Himalayan Bulbul and Striated Prinia in this habitat. Dark-breasted Rosefinch Unfortunately our arrival in Trashigang was delayed by some by Markus Lilje unannounced roadworks, which denied us the chance of visiting the small Trashigang Dzong.

The following day we started early, heading towards the famous Lingmethang Road and Thrumsing La National Park. This spectacular national park starts at 700 m and rises to an amazing 3780 m on Thrumsing Pass. This area is renowned for holding a plethora of Bhutan’s and, indeed, Asia’s most prized species, including numerous rare wren-babblers, the incredible Satyr Tragopan and loads more. We were to spend the next five nights camping in this fabulous national park; three nights at the lower camp, Yonkola, and two nights at the higher camp, Sengor. Before Wallcreeper by Markus Lilje reaching the Lingmethang area we did do a bit of birding from a small bridge and on the fabulous Kori La; the bridge gave us our first views of Brown Dipper, with Kalij Pheasant, another great Wallcreeper and Eurasian Crag Martin nearby. Kori La is a fantastic and often very productive pass and provided us with a lot of entertainment as we added a number of good birds to the list. Some of the species were found here included Golden- naped Finch, Rufous-capped Babbler, a female White-throated Redstart, Dark-rumped and Dark-breasted Rosefinches, the very difficult Plain-backed Thrush just sitting on the roadside, and all three possible bullfinches of the area: Brown, Red- headed and the scarce Grey-headed! We also enjoyed a fabulous flock of Rufous-necked and numerous White-crested Grey-winged Blackbird by Markus Lilje Laughingthrushes, Mountain Bulbul, Nepal Fulvetta, as well as Black-tailed Crake, which showed really well, before we arrived in Yonkola.

The Lingmethang Road holds so many highlights that we gradually sought and found over the days we had here, where we first worked the lower and more open broadleaved forests before we moved on to higher coniferous areas and rhododendron thickets. Mixed flocks are usually a strong feature of the birding here and provided us with many top species, including Black- throated and White-breasted Parrotbills, Golden-breasted Rufous-throated Wren-Babbler by Markus Lilje and Yellow-throated Fulvettas, Hoary-throated Barwing,

Trip Report - RBT Bhutan & Assam extension I 2014 6

Rusty-flanked and Sikkim Treecreepers, Rufous-chinned, White-throated and Chestnut-crowned Laughingthrushes, Rusty-cheeked Scimitar Babbler, Black-eared Shrike-babbler and Yellow-cheeked Tit. During a nightdrive we also managed to find our major target – the incredibly bizarre Hodgson’s Giant Flying Squirrel, which we managed to see very well, while Mountain Scops Owl called but refused to show up in the forest. The road in this area is well- known for being possibly the best anywhere for a variety of Wren-Babblers, with which we were very successful, finding Long-billed, Rufous-throated, Pygmy and Spotted, as well as the Sikkim Wedge-billed Babbler. One very big, but difficult target here, is Ward’s Trogon, which has become very difficult over the last few years – our efforts here were finally rewarded when we got lovely scope views of a male bird in forest near the road, amazingly just after some participants managed to get a fleeting glimpse of a female Satyr Tragopan in the same area! Golden-breasted Fulvetta An area a little below the campsite was also worth exploring by Markus Lilje and we found the scarce and shy Rufous-throated Partridge, Himalayan Cuckoo and Black-chinned and Striated Yuhinas here, in addition to Rusty-cheeked Scimitar Babbler and Golden-throated Barbet.

The time had come for us to start making our way up to Sengor, the higher of the two camps on the Lingmethang Road, which gets one into a completely different habitat with an entire new suite of first- class birds around this 3000 m camp. On the drive here we already noticed the avifauna gradually changing as we found a number of birds for the first time and had our only Crimson-browed Finch, as well as a close roosting and then flying flock of Snow Pigeon, Green Shrike-babbler and Fire-tailed Myzornis, which we also enjoyed near our Sengor campsite. The top target in this area is the exquisite Satyr Tragopan, although we knew it would be harder to find it here than in previous years due to ongoing road-widening construction work. After getting a few brief views and female birds we eventually hit the jackpot at our final opportunity, when a spectacular male walked off the side of the road and decided to stand and call from this position for a while, giving us unbelievable views of this amazing species. Some of the many other birds we found in this area included numerous rhododendron specials like Fire-tailed and Mrs. Gould’s Sunbirds, Spotted Nutcracker, White-browed Fulvettas, Stripe-throated and Rufous-vented Yuhinas Fire-tailed Myzornis by Markus Lilje and Black-faced Laughingthrush. In the coniferous forests we enjoyed views of a variety tits, including many Coal, Rufous-vented and Grey Crested Tits, as well as Rufous-fronted Bushtit and Goldcrest, Hodgson’s Treecreeper, Black-throated Thrush, White-winged Grosbeak, gorgeous Blood Pheasant, White-collared Blackbird, Rufous- breasted and White-browed Bush Robins, as well as excellent scope views of the vagrant Naumann’s Thrush – possibly a first for Bhutan. All this within the beautiful surroundings of the national park with its gorgeous forests – what a great Himalayan spectacle … although the air near the top of the pass was rather crisp, to say the least! Blood Pheasant by Markus Lilje

Trip Report - RBT Bhutan & Assam extension I 2014 7

Plain Mountain Finch, Bar-winged Wren-Babbler, Oriental Skylark and Red-billed Chough were other good birds we found here.

Our drive over the pass and onwards to Bumtang was fairly uneventful, with a few exceptions. After a couple more Blood Pheasant, we were fortunate to find a field that had a great number of both White- throated and Hodgson’s Redstarts, both just here at their end of their time in the lowlands before they head high into the mountains for the summer. Collared Grosbeak, Hen Harrier, Alpine Accentor and Red Crossbill also showed well before we got to the town of Ura, where we quickly found the biggest target here – Himalayan Beautiful Rosefinch amongst the more numerous Rufous-breasted Accentor. Ibisbill by Markus Lilje The town of Bumthang itself then also provided us with opportunities to try to find Ibisbill and Brown Parrotbill, both of which turned out to be very cooperative as we were able to watch these special species for extended periods in their riverside and bamboo habitats respectively. The Ibisbill in particular is always a huge target, being the only member of its family and having a fairly restricted range in the Himalayas. Other noteworthy species on this day were a breeding plumage Brown-headed Gull, Tickell’s Leaf Warbler, numerous Hodgson’s Redstart and Brown Dipper. We then all retired to our hotel for a much appreciated hot shower and solid bed after a few cooler nights of camping.

The following day we were off to Trongsa, but not before a quick stop at a wetland on the outskirts of Bumthang where we found a single Pin-tailed and Common Snipe, numerous Rosy Pipit and Little Bunting. On the day’s agenda was another stunning pass, this time Yothung La, which held more chances for some great species. The birds had clearly gathered in large numbers because of the excellent feeding conditions and flowering rhododendrons. Many of the same species we had previously encountered were found again, like Streak-breasted Scimitar Babbler and Yellow- billed Blue Magpie, as well as a variety of warblers, sunbirds and babblers, although it was great to get closer and better looks at some of them! In the afternoon we explored the Trongsa Dzong fairly intensively, a forbidding structure towering over the Mangde Chu Valley. In this area we were treated to amazing White-browed Piculet by Markus Lilje views of a hovering and diving Rufous-bellied Hawk-Eagle that ended up flying very close to all of us below. The latter part of the afternoon was then spent birding some forest nearby where we worked hard on a number of skulking species and managed to find Sapphire and Pygmy Flycatchers as well as a very vocal Spotted Wren-Babbler.

Trip Report - RBT Bhutan & Assam extension I 2014 8

As we headed back into the lowlands of central Bhutan for 2 nights we had to make our way past a lot of construction work being completed for a huge new hydroelectric plant near Trongsa. The very open grassland/woodland between Trongsa and Tingtibi then provided us with views of Blue-capped Rock Thrush, a distant but well scoped Little Forktail, White-browed Piculet, Common Rosefinch and Crested Bunting. We struck out along the Mangde Chu Valley on a fairly new road that hugs the precipitous drop down to the river, before we got to the small village of Tingtibi and our campsite nearby. This part of Bhutan is extremely wild and the stronghold for Golden Langur, which can be common in the area bordering the Royal Manas National Park in India. The birding on the whole was good here although the afternoons can be very slow, yet we certainly enjoyed the warmer weather. The much lower altitude means there are a variety of different species and these are what we were mainly after, managing to get views of Lesser Necklaced Laughingthrush, Golden Langur many Blue-bearded Bee-eaters, by Markus Lilje Pin-tailed Green Pigeon and one of the trickiest birds for the entire route, namely Pale-billed Parrotbill, which we found with a few White-hooded Babbler that they often associate with. Other species around these parts included Crested Honey Buzzard, flying Barred Cuckoo- Dove, Lesser Racket-tailed Drongo, Asian Emerald Cuckoo, Sultan Tit by Markus Lilje the bamboo loving Yellow-bellied and localized Rufous-faced Warblers, Chestnut-bellied Nuthatch, White-bellied Erpornis and Grey-throated Babbler. There were also a few mammals around beside the Golden Langur and we enjoyed good views of Indian Muntjac and Black Giant Squirrel as well as one of the biggest surprises of the tour – an Asian Black Bear, which we saw well during one of our late afternoon walks. We then drove back to Trongsa via the town of Zhemgang, where we found a few nice flocks with the more widespread birds like Rufous-necked Hornbill, Mountain Imperial Pigeon, Besra, Small Niltava, Fire- breasted Flowerpecker and Common Green Magpie showing well.

From Trongsa we made an early start for the high pass of Pele La, at 3400 m. The lower parts of the pass had a good amount of action going on and we were able to enjoy some views of scarce Tibetan Serin just feeding on the roadside and Fire-capped Tit. We enjoyed a good number of fly-by views of Himalayan Vulture near our rhododendron surrounded tea break. Black Kite and Common Kestrel also showed up as did a flock of Snow Pigeon, Streak-breasted Scimitar Babbler, calling Common Cuckoo and numerous other flock species of different altitudes including tits at the highest point and the widespread broadleaved species lower down. We also made a quick stop to look at a nesting group of Fire-capped Tit by Markus Lilje Asian House Martins at close range, where their distinctive all- white bellies and vents were extremely obvious and they can easily be differentiated from the more common Nepal House Martin.

Trip Report - RBT Bhutan & Assam extension I 2014 9

We finally arrived in the Punakha area in the late afternoon, unaware of the amazing number of scarce and special Bhutan birds that were awaiting us here. We ended up not only chasing the usual local specials, but also tried to find anything unusual in the area, as it quickly became evident that a number of good birds were using the valley as a resting point during their migration. During our time here were lucky with waterbirds in particular, finding Ruddy Shelduck, Northern Pintail, Gadwall, Eurasian Teal, Common Merganser, Greylag and Bar-headed Geese, Ferruginous and Mandarin Ducks and Great Crested Grebe – the last 5 of which are seldom seen in White-bellied Heron by Markus Lilje the country! Other birds along the Mo Chu and Po Chu were Ibisbill, River Lapwing, Temminck’s Stint, Green Sandpiper, Western Osprey and Pallas’s Fish Eagle, among others. The big target along the river though was of course the huge and critically endangered White-bellied Heron, which we hit the jackpot with as we found it soon after arriving in its range on the Po Chu, where it proceeded to give us some great views and even caught a fish in front of us! This is a brilliant bird to see and by no means ever a guarantee to find.

The other part of our birding time in the area around Punakha is spent in the Jigme Dorji National Park, which hosted us for a morning. This park has a lot of potential, but is best for just a short amount of time in the early morning, before activity drops off quickly within the excellent forest on the banks of the Mo Chu. Grey Treepies are common here, but we were more interested in other species, such as the very relaxed Speckled Piculet we got very close to, as well as Scarlet Finch and the very shy and skulking Slaty-bellied Tesia, of which many more were heard than seen. Crested Goshawk, a large flock of Speckled Wood Pigeon, Chestnut- Punakha Dzong by Markus Lilje crowned Warbler, Rusty-fronted Barwing, Slaty-backed Forktail, Orange-bellied Leafbird, Black- throated Sunbird, Rufous-capped and Golden Babblers, Great Barbet and Small Niltava were some of the other highlights here. The river itself was great for Brown Dipper, some of which allowed us to get extended views and showed off their skills in fast- flowing water, and also Tufted Duck in similarly rough water. After our fantastically prepared field lunch we then headed back to Punakha where we got to experience the remarkable Punakha Dzong, an amazing structure that is a serious focus point of Punakha and indeed the entire valley and possibly the cultural highlight of our trip. In addition to enjoying the Dzong’s architecture and atmosphere as well as the huge temple area, we were fortunate to witness a large number of monks that were in the Dzong, going through their chants and other rituals Golden Bush Robin by Markus Lilje that were very interesting to see and hear!

Trip Report - RBT Bhutan & Assam extension I 2014 10

Next we headed off for the last stretch of the tour, beginning with the drive to the Royal Botanical Gardens and then further to the capital of Thimpu. During our first part of the drive we found Brahminy Starling – virtually unknown in Bhutan, Citrine and White-browed Wagtails, 2 Slender-billed Oriole, Rufous Woodpecker and Black- winged Cuckooshrike. A walk through a section of forest here got us a bit of exercise as well as Snowy-browed Flycatcher, Great Barbet, great views of Yellow-billed Blue Magpie, Rufous-bellied and Darjeeling Woodpeckers, Grey-winged Blackbird, Hume’s Bush Warbler, Maroon Oriole, Speckled Wood Pigeon, Green- Tiger’s Nest Monastery by Markus Lilje crowned and Chestnut-crowned Warblers, Rufous-winged Fulvetta, wonderful views of Golden Bush Robin and Chestnut-crowned Laughingthrush. The drive to the top of Duchu La was quite uneventful, although we did find the scarce Chestnut-crowned Bush Warbler near the 108 stupas. We arrived in Thimpu in good time and decided to spend half an hour at the Golden Takin Sanctuary which displays Bhutan’s bizarre national mammal, before heading into town for a festive evening and a wonderful Bhutanese feast with some of our local assistants.

The following day we made our way straight for the Tiger’s Nest Monastery (after just a brief stop at the Paro sewage works, where we had very close Eurasian Hoopoe, Little Bunting, a vagrant Bay- backed Shrike and a large group of Rosy Pipit). The monastery is easily the most famous in all of Bhutan and it appears to perch precariously on a tiny rock ledge with seemingly no access point. It is quite remarkable to consider what an undertaking it must have been to get the materials up there to construct such an incredible structure. The weather was certainly on our side today and we enjoyed the fantastic scenery and walk up to the top of the Monastery. This was a wonderful day despite us only seeing a handful of different bird species, which included Rufous-fronted Bushtit, White- browed Fulvetta, the incredible Spotted, Chestnut-crowned, Black-faced and White-throated Laughingthrushes and Yellow-billed Blue Magpie. With lunch at the tea house, this was a great way to enjoy a change of pace towards the end of the tour, with Paro also allowing us the opportunity Little Bunting by Markus Lilje to have a look around the streets and shops.

The next day was to be our last full day in Bhutan as we climbed out of the Paro Valley and began our memorable time up Chele La, where the road tops out at 3988 m. This pass is undoubtedly the best place to try and find the resplendent Himalayan Monal, of which we managed to get some phenomenal views as, in particular, one male decided to walk and feed just meters below the bus on the road for an extended period of time. (We found a total of 8 monals near the top of this pass!) The morning certainly belonged to these incredible pheasants, but we also managed to rack up around 14 Blood Pheasant and 11 Kalij Pheasant during our time along this winding road. From a birding point of view other highlights for the day included a large flock of Himalayan Monal by Markus Lilje Altai Accentor, Spotted Nutcracker, Rufous-breasted Bush

Trip Report - RBT Bhutan & Assam extension I 2014 11

Robin, Black-faced Laughingthrush, Hodgson’s Treecreeper, Himalayan Bluetail, Himalayan White- browed Rosefinch and White-winged Grosbeak. We then returned to our hotel for our last night in Bhutan after a great final dinner. Near our hotel we also found more Pin-tailed Snipe, Black-throated Thrush and were surprised by possibly the first ever Rustic Bunting in Bhutan.

The Land of the Thunder Dragon certainly lived up to its reputation as one of the best birding tour destinations on the planet, and we all had a phenomenal time travelling and birding our way across this fabulous country. We can only hope that this amazing land can keep its charm through the ever- changing global environment, so that many more birders and nature enthusiasts alike can experience it in all its beauty.

ANNOTATED LIST OF BIRDS RECORDED

E = Endemic, NE = Near-endemic.

Pheasants and Partridges Phasianidae Swamp Francolin (NE) Francolinus gularis A total of three of these localized francolins were seen during our time in Kaziranga NP. Hill Partridge Arborophila torqueola Unfortunately this forest-floor species was only heard (frequently) during our time in Bhutan. Rufous-throated Partridge Arborophila rufogularis Another tricky species, 4 birds were seen briefly in forest edge below our Yongkala campsite. Chestnut-breasted Partridge Arborophila mandellii This seldom-seen species was heard in the Morong area of eastern Bhutan. Blood Pheasant Ithaginis cruentus One of the birds of the Bhutan tour and totally unforgettable! Seen on numerous occasions and very well on Thrumsing La and again on Chele La. Voted as the number 2 bird of the tour! Satyr Tragopan Tragopan satyra Certainly one of Bhutan’s most sought-after specialties and one of the great birds of the world. Of the five Tragopans, Satyr is certainly the easiest to target as Bhutan’s road system offers excellent chances for this outrageous species. We were not to be disappointed and in total we encountered five birds that included a male calling just meters from us on the grassy bank near Sengor! Himalayan Monal Lophophorus impejanus A spectacularly vivid species, of which we encountered an amazing 8 birds during our time up Chele La, including some unusually relaxed birds that allowed for extended viewings. The combination of colour, size and surroundings meant that nobody was surprised to have this voted as the top bird of the

Trip Report - RBT Bhutan & Assam extension I 2014 12 trip! Red Junglefowl Gallus We had numerous intimate encounters with this gaudy pheasant in Kaziranga NP in India, it was only heard in Bhutan. Kalij Pheasant Lophura leucomelanos The fourth of the pheasants to make it onto our top ten list for the trip. We had numerous excellent encounters with this species during the trip, including views near Thrashigang, Thrumshing La and Chele La; we were also able to see both the silver-bellied and silver-rumped races on the tour. NOTE: Clements splits this species into two separate species; Kalij Pheasant L. leucomelanos and Imperial Pheasant L. imperialis whereas IOC only recognizes one species, Kalij Pheasant L. leucomelanos. Grey Peacock-Pheasant Polyplectron bicalcaratum This elusive pheasant was heard calling in the Tingtibi valley near our campsite.

Ducks, Geese & Swans Anatidae Lesser Whistling Duck Dendrocygna bicolour Around 30 were encountered in Nameri NP, a huge flock later on the way to Bhutan. Greylag Goose Anser anser 2 birds were seen in Kaziranga NP, before a single bird showed up later below Punakha in Bhutan. Bar-headed Goose Anser indicus This species was pleasantly common at wetlands in Kaziranga, we also had a few in Nameri NP and even near Punakha in Bhutan later. A good species during the early tour in Bhutan. Common Shelduck Tadorna tadorna 3 birds were scoped well in Kaziranga NP, 2 further birds were seen later near Punakha. Ruddy Shelduck Tadorna ferruginea Commonly seen in Kaziranga and Nameri National Parks with several more sightings in Bhutan around the Punakha waterways. Mandarin Duck Aix galericulata A scarce vagrant in Bhutan, where we had a single stunning male in the Punakha area on 2 occasions.

White-throated Laughingthrush Garrulax albogularis One of the most commonly recorded laughingthrushes on the tour. We encountered massive flocks on many occasions with the highest numbers being along the lower Lingmethang Road. Lesser Necklaced Laughingthrush Garrulax monileger We had very good looks at some of the roughly 8 birds we had in two flocks near Tingtibi. Rufous-necked Laughingthrush Garrulax caerulatus A great-looking bird! We were surprised by a fast-moving flock on the outskirts of Kaziranga NP, before we located a numbers of good flocks at scattered locations in Bhutan. Grey-sided Laughingthrush Garrulax caerulatus An extremely shy species that was only heard on one occasion near Namling. Striated Laughingthrush Garrulax striatus This ubiquitous laughingthrush showed well on most days in Bhutan. Bhutan (Streaked) Laughingthrush Garrulax imbricatus This species was commonly encountered in shrubby habitat throughout much of Bhutan. NOTE: Clements lumps this species with Streaked Laughingthrush G. lineatus as Streaked Laughingthrush.

Chestnut-crowned Laughingthrush Garrulax erythrocephalus Fairly regular sightings were had throughout Bhutan. We saw this species on 7 separate days! Himalayan Cutia Cutia nipalensis Another extremely desirable bird that is probably easiest seen in Bhutan and Burma. Although Bhutan remains one of the best places on earth to see Himalayan Cutia it is always an elusive, unpredictable and nomadic species and is never guaranteed on any tour. We were very fortunate to find this species on 4 days, including some great views, including the first sighting near Morong. Blue-winged Minla Minla cyanouroptera Unusually scarce this year! Although we still enjoyed some great views on 4 days in Bhutan. Bar-throated (Chestnut-tailed) Minla Minla strigula Seen on 5 days in Bhutan, including a number of very good views on the lower Lingmethang road. Red-tailed Minla Minla ignotincta Less common than the above two species, its nuthatch-like behaviour is very distinctive and we found them on two days, although we never managed great views. Rusty-fronted Barwing Actinodura egerton This large and striking flock species was recorded on 5 days in Bhutan, first near Morong.

[Pale-billed] (Lesser Rufous-headed) Parrotbill Cleuasicus atrosuperciliaris One of the best birds in the Tingtibi area! This extremely scarce parrotbill was found together with the equally rare White-hooded Babbler when 2 birds were found at a fair distance. [White-breasted](Rufous-headed) Parrotbill Psittiparus ruficeps We had great close-up and extended views of this bird in a mixed flock on the lower Lingmethang road. What a great sighting!

White-eyes Zosteropidae Striated Yuhina Yuhina castaniceps This rather scarce, low elevation yuhina was seen on three consecutive days in the Zhemgang and Tingtibi areas while our initial views were on the road below Yongkala. White-naped Yuhina Yuhina bakeri This can be quite an uncommon species! We found them on 4 days in Bhutan, with first very good views in the Morong area. Whiskered Yuhina Yuhina flavicollis The most commonly encountered yuhina in Bhutan and a conspicuous member of mixed flocks. Stripe-throated Yuhina Yuhina gularis This large yuhina with its erect crest was commonly encountered at higher elevations in Bhutan. All passes that had good flowering groves of rhododendron held excellent numbers of this and the next species.
