Hong Kong - 8-17th November 2024
 |
| Dusky Warbler |
A family holiday combined with a birding trip, with the aim to get experience with some of the Eastern Palearctic specialities that occur as vagrants in Britain. This was my second time birding in Hong Kong, although my previous trip in 2018 was merely a precursor to ten days spent at Danum Valley in Borneo on the undergraduate Biology Field Course, so I wasn't birding intensively during the stopover - it was also in mid-summer so I didn't see a great deal. I tried to schedule this trip to get a mixture of the tail-end of autumn migration and also some of the winter visitors, as well as fitting it around the start of a new job as a postdoc.
I had arranged to meet up with a friend I knew from Oxford, Ton Yeh, who lives in Hong Kong and had offered to take me round a few sites, as well as let me know the latest bird news from the local WhatsApp chats - his help was greatly appreciated in seeing some of the key species.
Since I visited some of the locations multiple times I thought that rather than structure this blog post in chronological order in terms of what I did on a day-by-day basis, I would split it up into the different locations - the result is a sort of photo essay, rather than an exhaustive list of what I saw. Most of the focus is on two main sites, Long Valley and Mai Po, and I have only briefly gone over what I saw at Kam Tin, Tai Po Kau and Lion's Nature Park.
As always, please click on the photos to view them at full resolution - the Blogger website shows a compressed version in line with the text.
Long Valley
 |
| Black-winged Stilts were everywhere in the ponds - and unlike in Britain at point blank range |
Long Valley is an area of paddyfields and mixed agricultural land situated in the Northern Territories - it is the largest manmade freshwater wetland in Hong Kong. I had visited during my 2018 trip but saw very little other than Long-tailed Shrike. Since then, it has been closed for a couple of years to allow development into a nature reserve so I was very lucky that it reopened to birders literally on the weekend that I arrived in Hong Kong. It is situated only 15 minutes walk from my accommodation in Sheung Shui village so I visited almost every day - it became a sort of "patch" for the trip.
Long Valley is famous in autumn and winter for wader, pipit and bunting passage and the birding is quite easy - compared to Britain, the birds are very close and for this reason I concentrated most of my photographic efforts at this site. Resident birds include large numbers of egrets, herons, ducks and waterfowl, as well as passerines such as bulbuls and munias.
In Britain, I very much enjoy searching through pipits and wagtails and several gripping species in a Western Palearctic context showed very well here - including Red-throated Pipit, Olive-backed Pipit, Richard's Pipit, Eastern Yellow Wagtail and leucopsis White Wagtail.

A species that was high on my target list was Siberian Pipit, which would be a lifer for me. They are an uncommon passage migrant through Hong Kong in autumn, largely at wetland sites. Recently elevated to full species status from Buff-bellied Pipit, they look substantially different to the American Pipits that have occurred as vagrants in Britain.
A Siberian Pipit had been reported sporadically at Long Valley and I soon encountered a candidate bird wandering around with some White Wagtails. To be honest I didn't look at it too closely other than to verify that I wasn't one of the more commonly occurring pipit species, took a couple of photos and was largely satisfied that it was the Siberian Pipit after a quick look online for some comparison photos. I later included these photos when submitting my eBird checklist for that visit.
It was therefore rather shocking to receive a message from Ton a few hours later saying "People are asking if the Siberian Pipit picture is actually Water Pipit" on the local rarities WhatsApp group. I initially thought that I'd overlooked the status of Water Pipit in Hong Kong and that I'd suggested that a common species was something rarer. Upon checking that Water Pipit was actually something of a mega in Hong Kong (with only 6 previous records), I realised that my mistake was the other way round and slight panic set in - neither Ton nor of course I knew the local birders well enough to enquire as to whether they thought the identification was certain or the features that they were looking at to separate these species.
After madly trying to search for ID articles and pictures of both species online I realised that I actually knew very little about any of this and that I had better ask some people for help - therefore I sent the images to Ian Lewington and Ben Sheldon and awaited their response. By this point however, I could see that the suggestion of the HK birders was almost certainly correct, mostly because my bird had such dark legs, compared to the pinkish legs shown by most Siberian Pipits (why did I not think to check this feature before uploading the photos!!!). I was unsure however if any of the other features on my bird (reduced flank streaking for instance) were within the range of variation for Siberian Pipit.
Embedded here is an image of a Siberian Pipit taken at Long Valley in November from the Macaulay Library for comparison purposes - I had hoped to take some similar photos of this species myself!
The Asian subspecies of Water Pipit (Anthus spinoletta blakistoni) looks significantly different to the Water Pipits that we get in Britain, not that I regularly get a good look at them here anyway. It's therefore been a bit of a learning experience in their identification and I've summarised the main points below - thanks to Ben, Ian and also Per Alstrรถm for their comments.
Identification features for blakistoni Water Pipit versus Siberian Pipit:
1. Reduced flank streaking.
2. Paler brown mantle and rump.
3. Different face pattern - slightly less prominent moustachial stripe.
4. Heavier/different pattern of mantle streaking.
5. Dark legs.
6. Structural differences - slightly rangier, different head shape.
It is worth noting that this seems to be a particularly heavily marked Water Pipit (thanks to Grahame Walbridge for backing me up on this!), with a very dark, solid malar patch inviting confusion with Siberian Pipit. Lesson here though is that you should scrutinise everything completely, even in an unfamiliar context, and don't just assume!
Another group that I was particularly keen to see were the eastern buntings which occur as vagrants in Britain, and over the course of my visits was pleased to see Little Bunting, Chestnut-eared Bunting, Rustic Bunting (pleased to find three myself as it's a scarcity here), Black-faced Bunting and Yellow-breasted Bunting (a real speciality of the site). I also managed to twitch Common Reed Bunting, a Hong Kong rarity.

 |
| Yellow-breasted Bunting |
 |
| Common Reed Bunting, a different subspecies to the one we get in the UK (presumably pyrrhulina) - definitely looked a bit paler |
As well as the buntings, the low bushes and scrubby areas held large numbers of Dusky Warblers and Yellow-browed Warblers. Being Phylloscopus warblers they were a real pain to photograph, but a small pond full of lily pads allowed very close views, and I lucked out massively when a Dusky Warbler chose to briefly perch up only about 1.5m away from me (please click!).
 |
| Easily the best views I've ever had of this species |
 |
Despite this bird being partially obscured I quite like the composition of the photo
|
 |
| Sadly didn't manage to improve on this Yellow-browed Warbler image! |
Greater Painted Snipe is another Long Valley speciality and after some frustratingly brief flight views I wanted to get some shots on the deck - after a lot of searching I managed to locate the scrape which seemed to be their main roosting area.
 |
| Superb cryptic posture |
Some of the other waders present included
Common Snipe,
Avocet,
Black-winged Stilt,
Wood,
Green and
Common Sandpipers,
Greenshank,
Marsh Sandpiper,
Little Ringed Plover and an extremely confiding
Spotted Redshank.
 |
| Spotted Redshank - could literally get to within two metres of this bird |
 |
| Marsh Sandpiper |
I also had a few raptors drift overhead - Peregrine, Common Kestrel, Besra, Eastern Buzzard, Black-winged Kite and the omnipresent Black Kites.
 |
| Eastern Buzzard - very different jizz to Common Buzzard, reminded me more of Rough-legged Buzzard |
 |
| Male Besra |
I also managed to jam in on a twitch for Tundra Bean Goose - again less than ten records for Hong Kong. Extraordinary that this site had two megas and a whole host of rare/scarce species in under a week - does anywhere in the UK even come close?
 |
| A very confiding bird - there also seemed to be some initial confusion over its identity re. Tundra versus Taiga Bean Goose |

Other inhabitants of the paddyfields included Zitting Cisticola, Scaly-breasted and White-rumped Munias, Light-vented and Red-whiskered Bulbuls, Plain and Yellow-bellied Prinias, Oriental Magpie-Robin, Black-browed Reed Warbler, Oriental Reed Warbler, Stejneger's Stonechat and Long-tailed Shrike.
 |
| Zitting Cisticola |
 |
| Oriental Reed Warbler - very pleased to see this rather magnificent Acro as I thought it might be a bit too late in the season |
 |
| Plain Prinia - a very common species but always good value and relatively easy to photograph |
 |
Yellow-bellied Prinia - I found these to be a bit more skulking
|
 |
| Long-tailed Shrike - they clearly do a lot of ringing around here as the next photo also demonstrates |
 |
Stejneger's Stonechat
|
Overall this is just an absolutely fantastic site and I would no doubt be extremely satisfied patch working it, although avoiding all the toggers might get a bit challenging!

Mai Po
 |
| Olive-backed Pipit on a lovely bed of leaves along the entrance path |
Mai Po is a WWF-managed reserve on the Southern side of the Deep Bay that is internationally famous for its waders (especially as a site for Spoon-billed Sandpiper in spring). I was very keen to do some birding at this reserve despite a rather complicated application process for international visitors - I had to send in my BTO ringing permit as proof that I was interested enough in birds to warrant entry... The tickets were very expensive and the fact that I had to arrange my visit well in advance also meant that I would only be able to go there on one pre-booked day.
It was therefore sod's law that tropical cyclone Toraji ended up hitting exactly on the night before/morning of my visit - I had been anxiously watching the weather forecast during the week and a Typhoon 8 warning was put in place, which meant that all public transport was shut down and people were told to stay at home. Luckily, the warning was lifted at about 10:20am as the weather died down so I hurriedly got a taxi to the reserve - unfortunately I knew that this delay meant that I would have missed the optimal tide window for viewing the mudflats.
After hurriedly collecting my permit from the WWF centre I began birding from the three-floor hide overlooking the pools near the entrance, which were covered in ducks and egrets. Eurasian Teal, Wigeon, Shoveler, Pintail and Garganey were all present, although I was disappointed not to connect with Spot-billed Duck or the reported Baikal Teal. Both Black-faced and Eurasian Spoonbill were associated with the herons and egrets on the scrape, and I also got good views of Eurasian Bittern perched in the reeds.

| Probably the nicest hide I have ever been in |

The height of the hide meant that I could see most of the reserve from the top floor, and I was pleased to pick out two Eastern Marsh Harriers associating over the reedbed. They offered some fantastic photo opportunities against the distant skyscrapers of Shenzhen across the bay. Ospreys and Black Kites were also present.

The walk to the mudflats passed along a path lined with trees - a few winter passerines were present, including a couple of Daurian Redstarts and four Black-faced Buntings.

I completely failed to get any usable photographs of Black-faced Bunting on this trip so a sound recording will have to suffice - a really distinctive call, much like a Song Thrush.
Viewing the mudflats involved accessing the floating hides by walking along an intricate system of floating boardwalks leading through the mangroves - really amazing.
Upon entering the hide I was dismayed to find that, as expected, everything was miles away - a real challenge just to identify lots of the waders, let alone attempt to photograph them. I set up the scope and began squinting at the shoreline. Kentish Plover, Whimbrel, Curlew, Dunlin, Black-tailed Godwit and Grey Plover were all new for the trip, and I was very pleased to pick out a couple of Greater Sand Plover, which were a lifer for me. A single Caspian Tern was present with Black-headed Gulls but I sadly failed to see any other wintering gulls or terns.

 |
| The mudskippers provided quite a lot of entertainment, but tricky to time the shot to get them with their fin extended |
In the hide with me was a photographer who was quite intently waiting for something - actually the only other birder I saw all day! I assumed that he wasn't here just to photograph fiddler crabs and Chinese Pond Herons and sure enough, after a while the target bird appeared - a stunning Black-capped Kingfisher, which was territorial towards a nearby White-throated Kingfisher and later caught a couple of fiddler crabs.
 |
| Really demonstrating the autofocus tracking capabilities of the OM1 to be able to follow this speedy bird over a cluttered background! |
I had to rush back after only a couple of hours in the hide in order to make it out of the reserve by the 5pm closure time. Overall a pleasant if disrupted experience - it was also bizarre to see so few birders at Hong Kong's flagship reserve, compared to the huge numbers at Long Valley.
Kam Tin
 |
| Not the most scenic location |
A quick visit to Kam Tin mainly to see the wintering flock of Grey-headed Lapwing and other common waders on the river. The trees along the path also yielded the only Taiga Flycatcher of the trip.

Tai Po Kau
We spent one morning in Tai Po Kau for a bit of forest birding but it was hard going and even worse from a photographic perspective. Managed to see three of the skulkers - Pygmy Cupwing, Lesser Shortwing and Rufous-tailed Robin, as well as some common forest species but didn't encounter any large bird waves nor the hoped-for wintering thrushes. Also got bitten by ants which was a first for me!
 |
| Chestnut Bulbul - a really attractive and vocal species |
 |
| Lesser Shortwing - totally messed up the exposure of this photo in the gloom of the forest understory and realistically no amount of AI denoising was going to save it, but included here for completeness |
 |
| This giant centipede (Scolopendra) spent a while slowly descending a tree trunk and was fantastic to see |
Lion's Nature Park
An afternoon visit to Lion's Nature Park on quite a rainy day yielded a Two-barred Warbler and a Verditer Flycatcher but again no wintering thrushes. It was great to see the Two-barred alongside Yellow-browed Warblers and to hear it call - surprisingly different to the Greenish Warblers I've heard in Lithuania. A Black-winged Cuckooshrike was also new for the trip.
 |
Two-barred Warbler - very much a record shot of this bird, but shows the massive pale bill quite well
|
Summary
To be honest I was slightly blown away by the experience of birding in Hong Kong - I never expected to go to another country and immediately be involved in finding rare and scarce birds. The quantity of migrants passing through some of these sites is absolutely unbelievable compared to Britain, and it must be incredible to live here and be able to patch them regularly. The small size of Hong Kong also means that transport is easy and quick and it's possible to actually go around twitching everything if you were so inclined. Overall can't recommend it enough - I'm tempted to go back in April/May for peak wader passage.
