Himalayan Swiftlets on Yonaguni

I made my first trip to the Yaeyama Islands six years ago and my initial impression still holds true: Yonaguni is a rarity hotspot and not really worth considering if looking for Yaeyama specialties, Ishigaki's saving grace is Banna Park which has a fantastic network of quiet footpaths allowing easy access to the forest but on the whole it's not worth spending much time there as Iriomote is a far better for both native birds and a far superior away-from-it-all experience. That said, Ishigaki now has breeding Black-shouldered Kites... but they can be seen without actually leaving the airport.


After about three months of zero birding my schedule suddenly opened-up allowing me nine days of uninterrupted birding. Heaven. With just a couple of days notice I didn't think I'd be able to make reservations for a repeat of my previous trip covering all three main islands. So it proved, but with flights and Yonaguni car rental confirmed it didn't matter too much as I was quite happy to spend the whole time on Yonaguni. I'd day dreamt about finding Himalayan Swiftlet for ages, and now I'd have the chance to give it a good go. Though car rental on the island was no problem, the only accommodation I could find was for the first two and last three nights. So I was facing three nights in the car but as luck would have it my Ryokan had a cancellation resulting in only one uncomfortable night. One uncomfortable night, good grief I must be getting soft in my old age!


The ryokan only provided breakfast, no dinner, which was a bit of a concern because on my previous stay the shops weren't that well stocked and according to the ryokan owner the few local places to eat required pre-booking. However things have changed and it's quite easy to get a wide range of food in the shops now, there was even fresh fruit daily throughout my time there.


There are only two ferry sailings per week to the island so to get around all the last minute planning problems I chose to give sea-birding a miss and fly this time. I arrived on Ishigaki in the morning and had booked on the last flight to Yonaguni to give me time to look for the Black-shouldered Kites. It took 35 minutes to locate a rather distantly perched bird from the airport car park but after a few further minutes another bird gave excellent fly-by views. I'd actually allocated the final night of the trip to on Ishigaki just in case the Kites had been harder to see than I imagined. At least this would give me the opportunity to get a photo tick and visit Banna Park for owls.


The additional time I'd budgeted between outward flights meant I arrived on Yonaguni in the late afternoon and by the time I'd sorted out the car and found my accommodation there was no light for birding. Well, just enough to make out Common Mynas coming to roost on the cell tower outside my room. Day one and already the second Japan tick of the trip, I'd only managed two in the whole of 2018!


The weather was overcast next morning, indeed that was true of almost the whole time on the island, overcast with plenty of light rain. This was great, great for bringing in birds and keeping temperatures down. I spent the morning as much refamiliarising myself with the island as doing any serious birding. The first place I stopped and took a walk was at the eastern headland. On returning to the car I found the car lock didn't work. Really! The key may as well have been for a different vehicle, and of course my phone was inside the car. I once locked myself out of a rental car in the freezing pre-dawn of the eastern Turkish mountains, I was able to take out the windscreen on that occasion but cars are far more difficult to break into for a non-professional nowadays. There was nothing for it but to walk back to town, I was now even more pleased the weather was overcast. My car rental man wasn't a professional car thief either. Despite picking up the necessary tools to do the job at another garage he finally had to resort to a trusty hammer that he'd brought along from his own garage. Hammer and glass, only one winner there.


Not the greatest start to my time on the island I'd have to say, but unbeknown to me it wasn't all the doom, gloom and exasperation it seemed at the time... a Himalayan Swiftlet was on its way.


At some point in the afternoon I was at the opposite end of the island, not far from the island's, large pond. The number of hirundines was amazing, mainly Barn Swallows but also Red-rumped (c30), as well as Asian House (1) and Sand Martins (c10). There were also House (c12) and Pacific Swifts (2) zooming around too. This was what I wanted, this was surely my chance to find a Himalayan Swiftlet! Thinking something is so and it actually being so are more often than not two entirely different things but on this occasion... BOOM! There it was! At once obvious even to the naked eye, a bit like a martin with House Swift wings. It was fairly high and would often disappear for a few minutes but always came back. After the shock had worn off I set about getting the photographic evidence. This wasn't quite as straight forward as it might sound, now because it was quite high it wasn't too difficult to follow with the camera but the downside was the resulting images would never show any detail. The following two images is the most compelling of the evidence as gathered on that first afternoon...

It would sometimes fly below the line of hills in the centre of the island allowing a better appreciation of how remarkably nondescript the plumage was. Basically greyish-brown with a slightly paler rump but I could never get an in focus shot.


At some point I must have lost the bird and picked up a head-on House Swift by mistake because when I later checked the shots on the back of the camera, there was a good shot of a black-looking swift with a bold white rump. Cue self-doubt. It didn't matter how well I'd seen the bird in life, immaterial how plain the plumage had been; I was worried. How could I possibly have photographed a House Swift if this Swiftlet had been half as as eye-catching as I'd felt?


Needless to say I was back in the same area promptly next day, the weather was showery, drizzly, wet and grey. Terrific. There weren't any hirundines sailing round higher up, everything was close to ground level and in no time I'd found my Swiftlet again. Just as obvious as it had been yesterday though the small size was even more apparent. How could I have doubted this? With the bird dashing around so low my lack of photographic skills were about to face a much tougher challenge. Thankfully I was able to get a small number of shots which proved to myself it wasn't a House Swift and is in fact basically a martin with House Swift wings just as I'd first thought.

The question I now asked myself was whether I'd seen one Swiftlet or Two. It was clear on the second day that many birds had moved on. Barn Swallows were still present in huge numbers, as they were on all but the penultimate day of the trip, but lower numbers of Red-rumped Swallows and martins fluctuating daily throughout the trip were easy to keep tabs on and suggested there was a continuous passage of birds through Yonaguni. Barn Swallows were common throughout the island, in the lee of any shelter, but there were no other massive build ups elsewhere, no other locations regularly held Red-rumped Swallows or martins and this was the only site I ever saw either of the two Swift species. The penultimate day of the trip (April 16) was the first hot sunny day and Barn Swallow numbers dropped very noticeably, as if there were few lingering birds and onward movement was continuous. The final day (April 17) was again overcast with showers and either a huge new build up of birds suggesting passage had stalled once more. Not only were Barn Swallow numbers back up but Red-rumped and both martins had their respective highest totals of the eight-day visit.


No sooner had I realised the need to check through the flocks again than another Swiftlet flew past, below eye-level over a marshy overgrown cane field! Unfortunately this one didn't even pause let alone linger. At least I didn't need to embarrass myself with the camera. So definitely two and possibly even three Himalayan Swiftlets in the space of a week. That with just one pair of eyes looking for them.

Two dense wind-break hedges provided shelter for flying insects and immense numbers of Barn Swallows flew back and forth in the lee of each, testament to their aerial maneuverability. There were usually birds resting on the roughly ploughed field between the two hedges and in wetter conditions the field was carpeted with Swallows. I was surprised to see how many of them appeared to be in moult judging by what appear to be feather gaps creating white patches on the upperparts.

Crested Ibis and Oriental White Stork

After the good Hegura trip of the previous post, I woke early and mostly freewheeled back to the base of the headland. Basically the area is going to get the same birds as Hegura but they'll be able to disperse further more quickly and many will be harder to find. As there wasn't a large number of migrants on the island yesterday, I wasn't expecting the trees and bushes to be dripping with them here. How right I was.

By 8:30 I'd covered a fair amount of ground and the only migrants to show for tramping up and down the hills under the already hot sun was a small group of turdus thrushes clucking as they melted away. One at least was Japanese. And down in the village there was a large flock of mainly Red-rumped Swallows but with a few Barn, at least one Sand Martin and three Pacific Swifts.

It was then my phone pinged and a text on Sunday can only be for a bird. Sure enough someone I emailed while waiting for dawn got back to say a Crested Ibis was watched just 16km away at Suzu yesterday. He didn't have more details, where exactly other than in fields, or how long it might have been there. But only 16km for a Crested Ibis was too good to miss.

To be honest I thought the Ibis was nailed-on. Coastal villages have squeezed into every fingernail of flat space the hills neglected and their small associated areas of paddies cling to the slopes or shoehorn into narrow valley bottoms - this Ibis is going to be easy. Just a 16km dash. I'd never been to the western side of the peninsular, or southern which would be more appropriate up here at the crook, so eagerly cut across the peninsular with the bird already half ticked, totally oblivious to the awaiting reality.

Suzu is a moderately-sized rural city set on a coastal plain, around it an ocean of paddies with an archipelago of low hills creating inlets, straits and any number of secluded coves. My heart sank. There were Intermediate Egrets and grey Herons dotted singly or in small groups but no Ibis. Even on the extensive open areas there were so many ditches to lurk in and overgrown bunds to hide behind this wasn't going to be as straight forward as I'd imagined and ultimately ended in failure.

This is the second Crested Ibis I've chased in Ishikawa which seemed and I suppose still seems an easier bet than going to Sado Island. If the birds are successful on Sado, it must only be a matter of time before they re-colonise this former stronghold.

Because there hadn't been many migrants at the point and the weather certainly wasn't conducive to new arrivals I decided to drift homewards and with my mind already shifted to introductions it was only natural that the Oriental White Storks in Shiga presented themselves as an acceptable alternative. I'd never been to look for these birds but had pretty good directions and knew the general area quite well.

After trawling round the fields and seeing big numbers of egrets and Grey herons I was getting a familiar sinking feeling and stopped to gather my thoughts. No sooner had I switched off the engine when a Stork came gliding over the village through the nearside window. Then another, and another. Success! These birds come with no ethical listing ambiguity, I'd seen two in Japan before the re-introduction programme began, I could just enjoy them for the spectacular birds they are.

And yes, that egret is Great White.

hirundines to Long-tailed Tit

Four hirundines can be seen in Kyoto depending on the season and three of them breed in Kansai. Barn Swallow is a common and widespread breeder in urban as well as rural areas. It's not unknown for the race tytleri to occur in northern Shiga in mid-winter, I've seen a flock of about 30 in late December one year and a single in January in a subsequent winter. The flock were moulting primaries so presumably unlikely to travel far. It's strange to see Swallows flying low over a snow covered landscape as though it were a summer meadow.
Red-rumped Swallow only breeds at a couple of locations in Kyoto city and compared to Barn is also more localised as a breeder throughout the region. It's a common migrant over the city rivers, passing through later than Barn in autumn, there can be large numbers well into October.
Asian House Martin is a common breeder usually in association with rivers in forested areas and frequently nests under road bridges. The only urban colony I know of near Kyoto is under an elevated stretch of railway between here and Osaka. Sometimes parties can appear in in the city in mid-winter but they never linger long.
Sand Martin is purely a migrant and in autumn it can pass through over quite a protracted period. Again it can be seen along all the rivers and often over the fields at Ogura.

These Sand Martins were photographed on their breeding grounds in Hokkaido in August 2012.

This was another of the birds I photographed near Ashyu. I was puzzled by the dark patch on its breast side and when I cropped the image I was amazed to find another wing.  A heavily cropped version showing more detail is repeated below. As looks perfectly healthy and was gathering mud the supernumerary limb mustn't impare it in any way. Not having noticed this in the field, I'm left wondering whether it has a matching pair.

Long-tailed Tits are very common in and around the city as well as throughout Kansai in general. They can be found in woodland, in riverside scrub and city parks.
