Brownish-flanked Bush-Warbler – my final Taiwan endemic! Mini tour of Taiwan, December 7th-10th.

Alpine Accentor, Hehuanshan summit car park, December 8th.

Alpine Accentor, Hehuanshan summit car park, December 8th.

My girlfriend Jenna and I had booked and paid for a short break in the Philippines. However, with Typhoon Hagupit bearing down on the islands, we were forced to abandon our plans at the last minute and stay in Taiwan. On the plus side, I now had time for a three-day birding trip focused on mopping up some of the few remaining Taiwan specialities I still needed to see. My route took me up the beautiful east coast, through Taroko Gorge, across the high mountains at Hehuanshan, then through Wushe and back to Kaohsiung via Sun Moon Lake and Yushan National Park.

A short summary of sites visited and birds seen during the trip:

December 7th: Orchards near Dulan in Taitung County, at approximately Km 140 along Highway 11.

A short walk around the Lehuo Shoudo Moli homestay grounds and surrounding farming roads produced an excellent range of lowland species, including abundant Taiwan Bulbuls. Plenty of wintering thrushes were mainly Brown-headed Thrushes, but with at least one Pale Thrush among them. A nice selection of raptors included three each of Oriental Honey Buzzard and Crested Serpent Eagle, as well as an Osprey heading north.

December 8th: Hehuan Mountain summit.

Finally, I got my chance to see Alpine Accentor in Taiwan. The subspecies here is endemic to Taiwan and is a tough bird to see, necessitating a visit to very high mountains which can be hard to access. One of the best sites to connect with this bird is at Hehuanshan summit car park in winter, when a handful of Alpine Accentors forsake the bitterly cold peaks and seek out an easier existence among the cars and tourists at the viewpoint.

I found just one Alpine Accentor here, feeding unobtrusively along the roadside. It was incredibly tame and allowed an approach to within two feet or so. Other birds in the general area (mainly around the Hehuanshan visitor center a little lower down) comprised two Taiwan Rosefinches, a few White-whiskered Laughingthrushes, a Yellowish-bellied Bush-Warbler and six Asian House Martins.

December 9th: Chunyang Farm, near Wushe.

My third visit to this site in search of Brownish-flanked Bush-Warbler. Today I left nothing to chance, arriving at the site at 6.00am when it was still pitch dark. It was a cold morning and the birds took a while to get going, but by 7.00am bird activity was high and I finally found my target species. About 1.5km along the main asphalt road through the farm, I heard Brownish-flanked Bush-Warbler’s distinctive song. The bird was a real skulker and it took some time to get a glimpse even though it was singing constantly. It was also heard to call, a dry trrt and trrrt-trrrt, similar to Dusky Warbler.

Although the verdict is not yet unanimous, Brownish-flanked Bush-Warbler is now considered to be a full endemic species by many authors – not just a subspecies of the Chinese mainland form. As such, it is something of a personal milestone, being the last remaining Taiwan endemic bird for my list after nearly two years on the island.

Other excellent sightings at Chunyang Farm this morning included a pair of Snowy-browed Flycatchers, one Black-necklaced Scimitar-Babbler seen well (and others heard calling), six Rusty Laughingthrushes, and two Dusky Fulvettas.

Driving from Puli to Huisun later, I made a lucky stop at the river bridge along Highway 21 (almost directly under the freeway), where a flock of 15 Vinous-throated Parrotbills in tall grass were a long overdue Taiwan tick.

Taiwan Blue Magpies at Huisun, December 9th.

Taiwan Blue Magpies at Huisun, December 9th.

December 9th: Huisun Forest Park.

An afternoon here in search of Varied Tit for the year list. Birding at Huisun is very pleasant, with lots of birds to see, especially around the lower level main car park and trailheads.

Taiwan Blue Magpies were easy to find today, in fruiting trees next to the car park and around nearby buildings. Huisun is also a reliable site for Swinhoe’s Pheasant, and today there was a fairly tame party of four including an adult male at the base of the Duhchuanling Trail.

Varied Tits were vocal in the same area, with one bird finally seen well although they were surprisingly hard to catch sight of in the tall trees. I also saw a pair of Snowy-browed Flycatchers, along the first fifty meters of the Sihwufong Trail – at this altitude probably wintering birds rather than residents.

During the trip I also birded the Blue Gate Trail near Wushe (very quiet with little of note apart from common birds), the Ci-En Pagoda near Sun Moon Lake (again no sign of any Large Cuckooshrikes, but I did see Plain Flowerpecker which seems reliable here), and a very quiet walk in Yushan National Park, on the trail just off Highway 18 at Km 99.

Lifer: Brownish-flanked Bush-Warbler (total 1,792). East Asia tick: Alpine Accentor (total 878). Taiwan tick: Vinous-throated Parrotbill (total 271). Year tick: Varied Tit (total 264).

Winter suddenly arrived in southern Taiwan last night – I awoke to gloomy, overcast skies and early morning temperatures of just 19C (66F) in Kaohsiung. I dressed in jeans, a T-shirt, a thermal long sleeved top, a long-sleeved shirt, a thick hooded sweatshirt and a North Face waterproof jacket. This will probably sound ridiculous to people living in cold climates, but even with all those clothes on I was STILL a little cold riding my motorcycle. Maybe I have been in Taiwan too long.

Not wanting to drive too far in the cold conditions, I headed 45 minutes up the road to Cheting Marshes, on the Kaohsiung/Tainan border. For a while now, I’d been intending to thoroughly check the area out, getting in among the marshland instead of just viewing from the observation tower. Today seemed like a perfect opportunity to see what this excellent wetland has to offer.

The site delivered all that I expected and more. In winter, the main area of marshes is absolutely teeming with birds – big flocks of ducks, waders, and legions of herons including easy-to-find Black-faced Spoonbills.

Notable birds seen from the observation tower today included 40 Common Pochard (an exceptionally high count), 2 Gadwall, and a Spotted Redshank. This was a very good start as all three species are very scarce in Taiwan.

I then crossed to the south side of the road and spent about an hour and a half wandering about in the marshes and scrubland. I was hoping for a Vinous-throated Parrotbill (I am baffled as to why I have not encountered this species in Taiwan yet, as it is supposedly common), but instead found an even better bird – a Short-eared Owl. I flushed it from right under my feet, it then flew several hundred meters away and landed on the ground among short vegetation. Approaching with camera at the ready, I unfortunately failed to find it on the ground but did at least get a few record shots in flight when it flushed again. This is a rare winter visitor to Taiwan, and my first sighting of this bird in the East Asia region.

I also flushed a Purple Heron – only my fourth in Taiwan – and had reasonable views of an Oriental Reed Warbler skulking around a damp patch of vegetation. Other birds seen while walking in the marshes and scrub here included Yellow-bellied Prinia, Zitting Cisticola, Oriental Skylark and Red-throated Pipit – all fairly common in Taiwan but not birds I actually see very often. It’s good to get off the trails once in a while.

Returning to the main area of marshes on the northern side of the road, I walked up the western edge on a seldom-used path. Bird activity was generally very high, and I added Garganey and Richard’s Pipit to the day list here, as well as seeing my second Purple Heron of the morning. A Red-billed Starling flew over, an unexpected sighting. However, the undoubted highlight was a Great Bittern, first seen in flight as it crossed a pool, flushing several other birds in the process. It then landed in full view in the open and remained there for just a few seconds, at about fifty meters range, before walking slowly into the reeds. The reedbeds at Cheting are quite extensive and no doubt harbor one or two of these rare and highly elusive birds each winter. In two years birding in Korea, I failed to connect with this species, despite my local patch – Junam Reservoir – being a regular wintering site for them, so I was lucky indeed to see one today.

Next, I walked up the eastern edge of the main marsh, where a viewing platform allowed a good view of the flock of Common Pochard. A drake Mallard (scarce in Taiwan), plenty of Red-throated Pipits and Eastern Yellow Wagtails, and the majority of the Black-faced Spoonbill flock were also around here. My final stop at Cheting was the area of scrub near “Lovers Wharf”, a couple of kilometers to the south of the main marshes, which was very productive for starlings early in the year. Today just one White-shouldered Starling was seen, but two Yellow Bitterns and an Arctic Warbler made the ten-minute stop more than worthwhile.

I made three short stops on the drive back south to Kaohsiung. Yongan Wetland, a couple of kilometers west of Highway 17, had some common waders, a few Black-faced Spoonbills, and a flock of 75 Great Cormorants. Tardyhill Nature Park offers some woodland and scrub habitat and therefore slightly different species, and produced a Chestnut-tailed Starling on wires along the approach road, a Pale Thrush, four Black-naped Monarchs and a male Daurian Redstart. Finally, Yuanfugang Wetlands on the outskirts of Kaohsiung City is pretty overgrown and derelict these days but still produced four Pheasant-tailed Jacanas (a speciality of the site), at least 20 Indian Silverbills feeding on grass seeds, and a White-breasted Waterhen.

Back at home on the internet, I helped myself to a nice armchair tick – Northern Boobook, split from Brown Hawk Owl – which I consider to be a fair and just reward for getting stunning views of those two migrants at Qigu in the autumn.

East Asia ticks: Short-eared Owl, Great Bittern (total 876).

Black-necked Grebe, Budai and Aogu, November 25th

Highlights (74 species seen in total):

  • Black-necked Grebe 3 (2 Budai, 1 Aogu)
  • Purple Heron 1 (Aogu)
  • Gadwall 9 (Aogu)
  • Common Pochard 21 (Budai)
  • Garganey 3
  • Osprey 2
  • Black-shouldered Kite 2
  • Peregrine 1
  • Long-toed Stint c.50
  • Wood Sandpiper 4
  • Green Sandpiper 1
  • Avocet 10
  • Bar-tailed Godwit 2
  • Eurasian Curlew c.50
  • Yellow Bittern 1
  • Black-faced Spoonbill 100s
  • Brown Shrike 3
  • Long-tailed Shrike 4
  • Daurian Redstart 2
  • Black-faced Bunting 6

Black-necked Grebe is a rare winter visitor to Taiwan (Mark Brazil has it down as a one-star vagrant), so it was exceptional that I found them at two different sites today – perhaps evidence of a nationwide influx of this species.

First up was a pair at the far south end of Budai’s main lake, close to the electricity substation. They were fairly distant and dived constantly, but showed well enough to confirm the ID. Then, at Aogu a few hours later, I was astonished to find another in front of hide 6. This one showed at quite close range in excellent light, and I got some nice views – it’s been a while since I’ve seen a Black-necked Grebe, and I had forgotten how striking the glowing red eye can be.

Another good bird today was Gadwall – nine of them – loitering in front of hide 6 at Aogu. This is a very scarce wintering duck in Taiwan, but one which I was expecting to run into at some point among the huge numbers of common ducks I’ve been seeing these last few weeks.

Further quality Taiwan records today were an adult Purple Heron at Aogu, and still 21 Common Pochard at Budai.

Also noteworthy: a Peregrine, an Osprey and a Richard’s Pipit at Qigu, and a male Daurian Redstart and a good count of 6 Oriental Magpie-Robins in the coastal forest there. At Budai, I spent an hour getting lost on the farm tracks east of the main lakes, where there were at least 50 Long-toed Stints, 3 Wood Sandpipers, 9 Avocets and a Black-shouldered Kite among high numbers of commoner species – bird activity was very high in the general area today. At Aogu, the best of the rest were a Yellow Bittern, a Green Sandpiper, and at least six Black-faced Buntings along the roadside.

Taiwan ticks: Black-necked Grebe, Gadwall (total 266).

Heuglin’s Gull, West Coast Wetlands, November 18th

Adult Heuglin's Gull ("taimyrensis" form), seen from Highway 17 on the estuary at approximately Km 120.

Presumed adult Heuglin’s Gull (“taimyrensis” form), seen from Highway 17 on the estuary at approximately Km 121.

Living and birding in England for many years until 2005, I saw most of the gulls on the British list at one point or another. I used to enjoy scanning the vast gull flocks at Dungeness looking for a stray Caspian Gull, Yellow-legged Gull, or a winter Glaucous Gull. However, the identification and taxonomy of large gulls is not a subject that one has a lot of opportunity to get involved with in southern Taiwan, where they are generally very scarce winter visitors.

Driving south on Highway 17 on Tuesday afternoon, I was crossing a big river bridge at about Km 121 when my eye was caught by an adult gull on the estuary below. Even before I even stopped the scooter, my immediate reaction was that it was very dark on the mantle. The bird was wary, and I wasn’t too far away from it, but it was reluctant to leave the dead fish it had found. The mantle was a slaty-grey in color, several shades darker than on the Mongolian Gulls I had seen earlier in the day. Its legs were very bright yellow-orange, again quite unlike the dull pinkish legs of Mongolian Gull. The wings appeared especially long, another feature good for Heuglin’s Gull. Scanning identification papers and photos on the internet when I got home, the only feature that was perhaps abnormal for taimyrensis Heuglin’s Gull was the very white head (Heuglin’s Gull typically shows a lot of head flecking in winter), but there is much variation between individuals; this bird could have just been very late moulting out of breeding plumage.

According to the literature, the taimyrensis form of Heuglin’s Gull is a regular but uncommon winter visitor to Taiwan. The science of large gulls is very much a work in progress, but I am happy for now to be able to add it to my life list. It’s my first lifer since Slaty-legged Crake back in August.

In other news, visits to Cheting, Qigu, Budai and Aogu today produced a respectable total of 70 bird species. Perhaps noteworthy were a Black-faced Bunting and two Daurian Redstarts in the coastal forest at Qigu, two Ospreys on the estuary there, and a couple of Greater Painted-Snipes flushed from marshes along the Qigu embankment. At Budai, two adult Mongolian Gulls, 12 Common Pochard, a Garganey and a Richard’s Pipit, plus a huge flock of at least 800 Whiskered Terns resting on the marshes near Highway 17 at Km 134.5. At Aogu, no sign of the reported Hooded Crane, but plenty of wintering birds including Avocet and Black-headed Gull.

Of interest to birders visiting from overseas, Black-faced Spoonbills are currently common and easily found at all the sites mentioned.

Lifer: Heuglin’s Gull (total 1,790).

A lovely clear, cool morning up at Tengjhih. Kaohsiung’s smog could be seen creeping closer and closer during my visit, but it never seems to get all the way up to Tengjhih. I made sure to fill my lungs with plenty of clean air before driving back down the mountain.

I walked the main blue trail, starting at the village at Km 15 and proceeding clockwise. At birding pace, the walk takes 2.5-3 hours. Bird activity was high today, with plenty of thrushes seen and heard – however, only a few of them were positively identified, as they were very flighty and elusive in the abundant dense cover.

I heard both Taiwan Hill Partridge and Black-necklaced Scimitar-Babbler, and other notable Tengjhih records included Fire-breasted Flowerpecker, Black-faced Bunting, two splendid Black Eagles (reliable here), and the return of wintering Olive-backed Pipts and a Daurian Redstart.

Year tick: Eyebrowed Thrush (total 255).

A few hours on the west coast, from Cheting to Budai, showed that autumn migration is all but over, and winter birds are back in good numbers.

Ducks were much in evidence from the viewing tower at Cheting, including most notably seven Common Pochard on the right hand lake. This is a scarce winter visitor to Taiwan. Also here, 54 Black-faced Spoonbills, two Garganey, and high numbers of Sacred Ibis.

Qigu coastal forest was deserted by birds and birders, with no migrants seen there at all. Resident birds in evidence today included Oriental Magpie-Robin, Grey-capped Woodpecker, and a beautiful Peregrine soaring overhead. On the nearby Qigu reserve, thousands of waders on the mud were mostly too far away to identify, but Dunlins made up the overwhelming majority of the closer birds. Distant Eurasian Curlews and five Bar-tailed Godwits were seen. At least 300 Black-faced Spoonbills huddled together, with 150 resting Caspian Terns nearby. A Black-shouldered Kite drifted through, and there was a lone Richard’s Pipit on the embankment.

The Budai area was teeming with birds, with the best place being the complex of pools to the south of the road at Km 134.5 on Highway 17. Thousands of ducks included a further 20 Common Pochard – evidence of an unusual influx so far this winter? I added another Taiwan tick here – an adult Mongolian Gull – and a Black-headed Gull also flew through the area.

Taiwan ticks: Common Pochard, Mongolian Gull (total 263).

Mugimaki Flycatcher, Red-flanked Bluetail and Goldcrest, Qigu, November 4th

Highlights:

  • Goldcrest 1
  • Mugimaki Flycatcher 2 (1 male)
  • Red-flanked Bluetail 1 female
  • Daurian Redstart 6 (3 males)
  • Yellow-browed Warbler 2
  • Arctic Warbler 1

A significant change in the weather on Monday, with much cooler air across southern Taiwan, raised hopes that something good might finally have arrived at Qigu.

Nonetheless – being well used to disappointment at Qigu over the last few weeks – I reined in my enthusiasm, slept a little later than usual, had a leisurely breakfast, and finally arrived at the coastal forest at 9.30am. Initially it didn’t look promising, with no birder’s cars parked at the site – which is usually an indication that nothing much is around.

The first part of the forest seemed quiet, with the only bird of note a female Daurian Redstart. Then, near the pond, a lone Taiwanese photographer (English name Gordon) got me onto a bird he had just found. After something of a team effort, we managed to get reasonable views of a beautiful adult male Mugimaki Flycatcher. It was very mobile and stayed high in the trees, often obscured by branches, making photography difficult even for Gordon’s long lens.

Already the trip was worthwhile, and I wandered off along the eastern shore of the pond, where two male Daurian Redstarts were chasing each other around, and then an ever better bird appeared – a female Red-flanked Bluetail giving great views perched on a fallen log. I went to find Gordon, who managed some excellent shots of the bird.

My favorite area of Qigu coastal forest is also the area that is hardest to access, because it’s the part that’s covered with the most driftwood and damp gullies. It’s about two-thirds of the way through the forest, on the landward side, and today it seemed especially sheltered from the breeze and rich in insects here. In one small area, I quickly found two Yellow-browed Warblers, a second Mugimaki Flycatcher (this one a female), an Arctic Warbler, and outstandingly a Goldcrest, which was calling frequently and keeping to the tops of the pines. I went to fetch Gordon again, who spent an hour or so at the spot and eventually came away with some very satisfactory photos of this difficult-to-photograph species. Goldcrest is a rare migrant in Taiwan, especially so in the south of the country.

Leaving the forest, a drive along the length of the Qigu embankment produced a couple of Richard’s Pipits, another Daurian Redstart, and plenty of extremely distant Black-faced Spoonbills and Caspian Terns on the mud.

At Cheting Marshes, halfway back to Kaohsiung, I spent an enjoyable twenty minutes in the viewing tower, from which large numbers of herons, ducks and other water birds can be easily seen. Perhaps notable were three Garganey, an Avocet, two Whiskered Terns, plenty of Sacred Ibis, a Eurasian Kestrel, and a beautiful Long-tailed Shrike.

Taiwan ticks: Mugimaki Flycatcher, Goldcrest (total 261).
