Common Gulls at Jinzhou Bay, Dalian

One of the highlights of my recent trip to Liaoning Province was the opportunity to see so many gulls at Jinzhou Bay (we estimated over 4,000).  This number must make Jinzhou Bay one of the premier gull-watching sites in northern China (if you know of a comparable site, please let me know!).  The channel of running water alongside the landfill tip was a favoured haunt of Common Gulls (Larus canus) and, over the two days I spent at this site, I saw several young birds, presumably of both the subspecies found in this area – kamtschatschensis and heinei.  Here are a few images and personal comments.  Please let me know if you disagree with my identification or if you have more to add.

The kamtschatschensis bird, in particular, would certainly stand out if it turned up in the Western Europe!

First winter Common Gull of the subspecies kamtschatschensis, Jinzhou Bay, Dalian, Liaoning Province. Note the dark, well marked underparts and strongly barred undertail coverts.
First winter Common Gull subspecies heinei, Jinzhou Bay, Dalian, Liaoning Province, 25 January 2012. Note the very clean, white underparts.
First winter Common Gull ssp kamtschatschensis, Jinzhou Bay, Dalian, Liaoning Province, 25 January 2012. The upperparts are well-marked and the moult of juvenile feathers seems to be later than the heinei ssp below.
First winter Common Gull ssp heinei, Jinzhou Bay, Dalian, Liaoning Province. Much cleaner, especially the uppertail, and more advanced moult, notably on the scapulars.

It’s difficult to tell from these images but, in the field, the kamtschatschensis bird appeared to be stockier with a slightly longer bill.

Second winter Common Gull, Zhuanghe, Liaoning Province, 28 January 2012. I suspect this individual is of the subspecies kamtschatschensis. Aged as a second winter due to the presence of some adult-type wing feathers, the small white 'mirror' on the outer primary (P10) and the relatively clean tail. Note the brownish fringes to some of the coverts, a good feature of second winter kamtschatschensis.

Gulling

Gulls… They say that, as a birder, you either love them or hate them. Well, I am definitely in the ‘love’ category, even though I find the large white-headed gull complex an identification challenge.

Living in Beijing, a very dry and land-locked metropolis, sightings of any gulls near to home are few and far between. So the opportunity to visit Choshi, just east of Tokyo, was too good to miss.

This port, situated on the edge of the vast Pacific Ocean, is home to hundreds of fishing boats and I saw huge catches of yellow-fin tuna, mackerel, sardines and some larger species, including what looked like swordfish. The sheer quantity of fish, and its associated waste and by-catch, means that there is plenty of food for gulls and, during winter, they are attracted here in their thousands. The most common gull by far is the Black-tailed Gull, an east Asian endemic, closely followed by Vega (a Herring Gull lookalike) and Black-headed Gulls (ssp sibiricus). Among these are reasonable numbers of Slaty-backed Gulls with a few Glaucous-winged, Glaucous, Common (ssp kamtschatschensis) and the odd Mongolian Gull (Larus cachinnans mongolicus) mixed in. During my visit I also saw a Ring-billed Gull (the first Japanese record of this American species was as recent as 2002).

Access is easy and free – I had no problem at all walking around with binoculars and a camera and the great thing for photography is that you are generally looking north from the harbour towards the water, meaning that the winter sun is mostly with you.

If you are interested in gulls, this is as close to heaven as it gets. However, Choshi is not just about gulls – many more sought after species can be seen well here. The local Black Kites (ssp lineatus or ‘Black-eared Kite’) also enjoy the bounty provided by the fishing boats and there are good numbers of Temminck’s and Pelagic Cormorants plus Black-necked and Slavonian Grebes just offshore. A single Harlequin Duck near the lighthouse at Cape Inubo was a nice addition to my visit and Dusky Thrushes were common in suitable habitat. Around Cape Inubo there were also Blue Rock Thrushes, Japanese White-eyes, Bull-headed Shrikes and a single Brown Thrush.

I will follow this general post with some detailed posts about specific species but, in the meantime, I am posting a selection of images to give you a feel for the place.

Getting there: Choshi is within easy reach from Tokyo and Narita airport and a day-trip from either is very doable. Catch any train from Narita Airport to Narita and change for the hourly local service to Choshi, which takes around 90 minutes (cost cGBP10). The staff at the airport are incredibly helpful and will point you in the right direction and give you advice on purchasing a ticket. Once at Choshi, it is a 5-10 mins walk to the north to reach the river Tome, from where you can walk east along the whole length of the harbour for 3-4 km (the whole stretch is good for gulls). Further along the coast to the south-east lies a famous lighthouse at Cap Inubo. It would probably take 2-3 hours to walk to this point from the station, so a taxi is a good option if you want to explore this area (but beware, taxis in Japan are expensive – it cost me almost GBP 20 pounds for the 10-minute journey from Choshi town centre to the lighthouse). I found only one hotel in Choshi where the staff spoke any english – the Choshi Plaza (half way from the station to the river on the right hand side) – which, at GBP50 per night, is reasonable value in Japan.

Best areas: there are boats all along the harbour wall running from just east of the Tome bridge to the sea, with three fish markets interspersed. The best area for viewing gulls depends on the activity in the harbour and which boats are offloading their catch but, about half-way along, there are a couple of good areas of sea wall parallel to the road which are good places to scan – hundreds of gulls rest here and there are good numbers all day.
