GUEST POST: An Introduction to the Three Widespread Herring-type Gulls in East Asia

Editor’s note: Dr. Nial Moores is director of Birds Korea and an authority on gulls. In this guest post, written especially for shanghaibirding.com, Moores describes the three widespread Herring-type gulls of East Asia. One of these is Taimyr Gull Larus (heuglini) taimyrensis. Moores points to the photos above to support the recognition, contested by some, of Taimyr Gull as a separate taxon. The panels show two Herring-type gulls, both adults, photographed on the Huangpu River in downtown Shanghai on 18 March 2017. The panels at left show Mongolian Gull Larus mongolicus. The right-hand panels show Taimyr Gull. The Mongolian is in full breeding plumage, as evidenced by its spotless white head. The Taimyr, by contrast, still shows streaking on its head, an indication that it has not yet attained full breeding plumage. The Taimyr shows as well upperparts darker grey than those of the Mongolian. These differences, Moores writes, show that the birds in question are two species.

Experts agree that Taimyr Gull is distinctive; what they disagree on is how to classify it. The IOC does not even recognize taimyrensis as a taxon, let alone a full species. Moores laments this state of affairs. The disagreements, Moores maintains, would melt away if more were known about these gulls. Moores wrote the post, and I am proudly publishing it, with a view toward fostering new knowledge. Birders, fear not the Herring-type gulls!

In his post “Loons Near Pudong Airport” (20 March 2017), Craig Brelsford posted an image of a Slaty-backed Gull and of a wing-tagged gull, referring to all the gulls in the background as Larus vegae vegae or Larus vegae mongolicus. In a public comment, I asked about Craig’s omission of Taimyr Gull Larus (heuglini) taimyrensis, leading to an exchange of e-mails between us and an invitation by Craig to post about this taxon. Below, therefore, are a few thoughts on Taimyr Gull, as depicted in Craig’s images taken 18 March 2017 on the Huangpu River in Shanghai, and a brief explanation of why many gullers no longer consider taimyrensis, vegae, and mongolicus to be the same species.

Taimyr, Mongolian, Slaty-backed. 18 March 2017. Craig Brelsford.
Three Larus gulls of East Asia. Moores calls the gull far L Taimyr Gull Larus (heuglini) taimyrensis. The middle gull Moores describes as Mongolian Gull L. mongolicus. The middle and left-hand gulls show clear differences, attributable, says Moores, not to individual variation within a single species but to the two gulls’ being members of two species. Note, for example, the differences in leg color (yellow in Taimyr, pink in Mongolian). Observe also that the Mongolian shows an all-white head because it is already in full breeding plumage; the Taimyr, by contrast, still shows streaking on the nape, because it is not yet in full breeding plumage. Mongolian assumes breeding plumage earlier than Taimyr because Mongolian breeds farther south and earlier in the year than Taimyr. Taimyr breeds on the Taimyr Peninsula in Siberia, 5,000 km (3,100 mi.) from Shanghai, and it does not arrive on its breeding grounds until after the summer thaw in mid-May. The preening gull far right is second-winter Slaty-backed Gull L. schistisagus. Binjiang Park (31.2356935, 121.4973863), Huangpu River, Shanghai, 18 March 2017. (Craig Brelsford)

Visit a local river mouth, coastal wetland, or beach in winter, and the chances are high that you will see gulls. Some of the species found in East Asia, such as the Black-headed Gull Chroicocephalus ridibundus and Mew (or Common) Gull Larus canus, have a very wide geographic range and should be as familiar to domestic birders as they are to visiting birders from Europe and parts of North America. There are also a few gulls which are much more likely to stand out as different in structure and plumage. These include Relict Gull Ichthyaetus relictus and Saunders’s Gull Chroicocephalus saundersi. Both are highly distinctive East Asian “specials”; both are dependent on tidal flats in winter; both are globally Vulnerable; and both are confined entirely to this region and lack any counterpart elsewhere in the world (compelling evidence of the importance of the East Asian tidal flats to biodiversity).

And then there is a group that seems to fit neither of these categories: the so-called “Herring-type” gulls. There are three main Herring-type taxa found in this region, which the IOC Checklist effectively treats as one and the Birds Korea Checklist (Moores & Kim 2014) treats as three species: the Mongolian Gull Larus mongolicus, the Vega Gull Larus vegae and the Taimyr Gull Larus (heuglini) taimyrensis. All three of these gulls are widespread in this region in winter and can even be locally abundant. Importantly too, all three also have some kind of counterpart in other, better-researched regions. The Mongolian Gull in many ways looks most similar to the Caspian Gull Larus cachinnans of western Eurasia–most especially in that adults can look almost white-headed in mid-winter (at a time of year when more northern-breeding Herring-type gulls usually have densely spotted or streaked heads) and in their first-winter plumage. The Vega Gull looks more similar to the European Herring Gull Larus argentatus or the American Herring Gull Larus smithsonianus. As adults, all three have heavily streaked or mottled heads in non-breeding plumage, and all three are typically pink-legged at all ages (though with local exceptions–including in East Asia the paler-backed, yellow-legged individuals sometimes considered to be birulai, a subspecies of Vega Gull).

There are many similarities between Vega, European Herring, and American Herring Gulls in juvenile and immature plumages too, including, e.g., obvious notching on the tertials in the vast majority of juveniles and first-winters (first cycle), and in flight an obvious paler area on the inner primaries–often called a “window” by gullers–contrasting with a darker outer wing. The Taimyr Gull instead looks closest to the Lesser Black-backed Gull Larus fuscus of northern Europe in that adults are quite dark grey above and can have bright-yellow legs. The juvenile upper wing of both species also looks rather similar too, in that this pale area across the inner primaries is less obvious than in Vega or either of the Herring Gulls, while both Taimyr and Lesser Black-backed Gulls also have darker secondaries and a dark band across the greater coverts (though less striking in Taimyr than in Lesser Black-backed Gull).

NOTES ON TAIMYR GULL

Mongolian Gull (wing-tagged) and Taimyr Gull (directly behind Mongolian). Moores: 'The adult to the rear has extremely bright yellow legs and a vividly coloured bill, with the red on the gonys unusually bleeding up onto the upper mandible. The bird in the foreground, known by that wing tag to be from the breeding grounds of Mongolian Gull, has much weaker yellow-pink tones to the legs and the red confined to the lower mandible.'

(Craig Brelsford)

In Craig’s image above from the Huangpu River in Shanghai, it is easy to see that at more or less the same angle, the upperpart grey of the adult to the rear is darker and a little slatier-looking than that of the wing-tagged gull in the foreground. A few other differences should be easy to pick out. One is the colour of the bare parts. The adult to the rear has extremely bright yellow legs and a vividly coloured bill, with the red on the gonys unusually bleeding up onto the upper mandible. The bird in the foreground, known by that wing tag to be from the breeding grounds of Mongolian Gull, has much weaker yellow-pink tones to the legs and the red confined to the lower mandible.

Leg colour can change seasonally, and bill markings change with age and apparently season too, but structure is more constant. The rear bird has a thicker-based bill and thicker-looking legs and also longer-looking wings, with at rest a rather more obvious extension of the primaries beyond the tail than shown by the Mongolian Gull in the foreground. There is another obvious difference: the streaking on the nape of the bird to the rear. Extent and density of head streaking is also a feature that changes seasonally and individually in gulls. What is important here is that on the same date, two apparently similarly aged gulls show several marked differences from each other, including that one of them still has a lot of streaking on the hind-nape and some grey wash near the eye; while the other, the Mongolian Gull, is already unstreaked and white-headed.

Head and legs of Taimyr Gull (L) and Mongolian Gull. ‘The rear bird has a thicker-based bill and thicker-looking legs,’ Moores writes. ‘There is another obvious difference: the streaking on the nape of the bird to the rear. Extent and density of head streaking is also a feature that changes seasonally and individually in gulls. What is important here is that on the same date, two apparently similarly aged gulls show several marked differences from each other, including that one of them still has a lot of streaking on the hind-nape and some grey wash near the eye; while the other, the Mongolian Gull, is already unstreaked and white-headed. … The adult bird standing next to the Mongolian Gull is what an increasing number of birders now call Taimyr Gull.’ (Craig Brelsford)

The combination of these differences (in structure, plumage tone, coloration of the bare parts, and head streaking) gives me confidence that these are adults of two species. And to be sure, while the adult Mongolian Gull in the foreground could perhaps be overlooked as a dark-looking American Herring Gull if seen in North America (where leg colour is more variable than in much of Europe: see here) or a big Caspian Gull if seen in Europe, an adult like the one just behind, with such yellow legs and such grey upperparts, would never be identified by any serious birder in Europe or North America as a Herring Gull. This bird would much more likely be identified as a Lesser Black-backed Gull instead–even if an odd-looking one. Notably, although the Lesser Black-backed Gull is largely restricted to breeding and wintering in Europe (with small numbers occurring in North America), the kind of gull in the image is quite common in East Asia. Here in Korea, I have seen several “pure” flocks of 40 to 50 birds looking just like this in March and April, and I counted a single flock of several hundred in Rudong a couple of Septembers ago. And often adults like these are accompanied by immatures of different ages–almost all of which after years of observation similarly fit neatly into an expected pattern of structure and plumage. Yes: The adult bird standing next to the Mongolian Gull is what an increasing number of birders now call Taimyr Gull.

Another look at 'Taimyr Gull.' Craig Brelsford.
Another look at Taimyr Gull. Note grey back, long wings, and strong, yellow legs. (Craig Brelsford)

The Taimyr Gull is a far northern-breeding species (confined, as far as we know, to breeding only on the Taimyr Peninsula: see van Dijk et al. 2011). Most adults do not attain full breeding plumage with gleaming white heads and bright bare parts until the middle or end of April. The most direct route from the Yellow Sea to their breeding grounds entails a flight of about 4,500 km (2,800 mi.) across land and environments which are hostile to gulls all the way. These gulls should not reach their breeding grounds too early, of course, either, because much of the Taimyr Peninsula will still be under snow and ice until the middle of May–a cold and deadly place for a gull until the summer thaw begins. Therefore, many adult Taimyr Gulls remain in the Yellow Sea until late April and early May, acquiring their full breeding plumage late before migrating rapidly, perhaps more or less non-stop, up to the northwest.

Wing projection of mongolicus (top) is shorter than that of taimyrensis (bottom). Moores: ‘It is at least in part the huge distance that Taimyr Gulls need to fly over land between their breeding grounds and the rich fishing grounds of the Yellow Sea and south China coast that requires them to be so long-winged.’ (Craig Brelsford)

It is at least in part the huge distance that Taimyr Gulls need to fly over land between their breeding grounds and the rich fishing grounds of the Yellow Sea and south China coast that requires them to be so long-winged; and the brevity of the Arctic summer also determines when juveniles can start to moult into their next plumage and how much of their plumage they then need to moult. As in Lesser Black-backed Gull and Heuglin’s Gull Larus heuglini (the latter for now listed by the IOC as Larus fuscus heuglini, i.e., a subspecies of Lesser Black-backed), it appears that this moult is much more extensive in Taimyr Gull than in Vega, American Herring, or European Herring Gull.

Juvenile Taimyr Gull Larus (heuglini) taimyrensis, October 25th, Pohang, Republic of Korea. In October, all Taimyr Gulls (and Vega Gulls) are in a rather unremarkable, brown juvenile plumage making separation from Vega Gull L. vegae of the same age rather challenging. This is the plumage both species retain until December or January, several months later than Mongolian Gull L. mongolicus. Note however the rather confident, flat-backed structure of this individual; the rather dark greater coverts; the contrastingly dark centres to the scapulars (making the bird look scaly); and the contrast in the head, with the ear coverts obviously darkest - all features suggesting the otherwise slimmer, more attenuated-looking Lesser Black-backed Gull L.fuscus from Europe.

Their first great transformation–from brown juvenile into a grey, white, and black first-winter–starts quite late, however. Most Taimyr Gulls, like Vega Gulls, are in juvenile plumage through December. Sometime in January or February of their second calendar year, Taimyr Gulls begin a rapid moult, with many by the end of February starting to look white-headed, and some showing patches of dark adult-type grey plumage in the scapulars and mantle by March and especially by April. For one or two months (from mid-February to mid-April), these young Taimyr Gulls can then start to look quite similar to young Mongolian Gulls, a few of which also seem to start to show some adult grey in their upperparts. The upper wing still looks different, though (especially the pattern on the inner primaries), and among the other differences visible on birds on the ground is that the base grey on the scapulars is quite dark; and the anchors and barring that overlie this grey area are much coarser than in Mongolian Gull. Most Taimyr Gulls have very coarse streaking on the nape, too. And all this new plumage, being so new, looks really fresh. They therefore do not have worn-out looking tertials like most Mongolians, especially locally bred birds. Of interest perhaps to those who enjoy studying gulls, in my 25 years in this region, and although both second-calendar-year Taimyr (regularly) and second-calendar-year Mongolian (sometimes) can show adult-type grey, I have not yet seen a single second-calendar-year Vega Gull in March or April with obvious adult grey in the plumage.

MONGOLIAN GULL, A MORE SOUTHERLY BREEDER

Mongolian Gull, Binjiang Park (31.2356935, 121.4973863), 18 March. This gull was tagged on 27 May 2013 in Mongolia.
Mongolian Gull at Binjiang Park, Shanghai, 18 March 2017. This gull was wing-tagged at Telmen Lake, Mongolia, 2,820 km from Shanghai. Telmen Lake is a bit more than half the distance between Shanghai and the Taimyr Peninsula, where Taimyr Gull breeds. Moores says that because of the shorter distance between its breeding grounds and winter range, Mongolian Gull attains breeding plumage earlier than Taimyr Gull, and it is shorter-winged. (Craig Brelsford)

The Mongolian Gull (as far as we know) has a rather wider breeding distribution than Taimyr Gull and probably than Vega Gull. Mongolian is the species that breeds, or used to breed, north to Lake Khanka on the Sino-Russian border, northwest at least to Lake Baikal, and southeast to our region. This, after all, is the Herring-type gull that nests alongside Black-faced Spoonbills and Chinese Egrets on Yellow Sea islands in Korea and presumably very locally in China too. Breeding further south, their breeding grounds thaw earlier than those of the Taimyr Gull, which in turn means that Mongolian Gulls have to progress into breeding plumage much earlier than either Taimyr or Vega Gull.

By mid-February many adults are white-headed, and many are already prospecting nest sites. Here in Korea, by March many are paired up, giving their distinctive nasal braying courtship calls; birds can be sitting on eggs in April; and many of the young will have fledged by early June–this is before many Taimyr and Vega Gulls will have even started egg-laying! Mongolian Gulls (at least those born and raised in Korea) retain their dark brown juvenile plumage only until August or early September, before they start to moult rapidly into a quite pale-looking first-winter plumage. And by January, because this plumage is already several months old, young Mongolian Gulls already show a lot of wear, with extensive pale areas across the inner primaries contrasting with darker internal markings, which sometimes suggest black golf clubs.

First-winter Mongolian Gull Larus mongolicus, October 25th, Pohang, Republic of Korea. By October this bird, like probably all Mongolian Gulls, has moulted out of the brown juvenile plumage into a much more contrasting First-winter plumage. Note that the head is already almost white, and the bill is already developing a paler base. If you look closely at the tertials you can see that the edges are already very worn with ragged edges (i.e. they are already ol feathers). This fraying is not shown by Vega or Taimyr Gulls until March or April at the earliest, as they hatch much later than (locally-raised) Mongolian Gull. Nial Moores.

Look carefully at the edges of the tertials, too: These often have uniquely frayed edges in mid-winter and early spring. These pale young Mongolian Gulls are the birds that look a lot like young Caspian Gulls, and are presumably much of the reason why Malling Olsen and Larsson (2004) treated Mongolian Gull as a subspecies of Caspian rather than lumping the taxon with Vega. They just look so different. In this region, we also get to see these young Mongolians accompanying adults on the tide-line and also often in freshwater habitats–along rivers and in lakes. This is an ecological niche they occupy which is largely avoided by both Taimyr and Vega Gulls. This is therefore the large gull of the Han River in Seoul and the Taedong in Pyongyang; and presumably of floodplain wetlands of the Yangtze River (and possibly of the Huangpu River in downtown Shanghai). As early as January, many of these young birds are already largely white-headed, with beautifully patterned scapulars (pale grey bases with dark rows of anchors), and often pale breasts and bellies: beautiful and strikingly different from either Taimyr or Vega Gulls at this time of year–both of which in January (as described above) are still mostly washed brown above and below, with heavily patterned heads and all-dark bills.

Structurally too, most Mongolian Gulls can be pretty obvious, being rather bulkier and more powerful-looking than Vega or Taimyr Gulls: a modest counterpart to the Great Black-backed Gull Larus marinus of the North Atlantic. And just like Great Black-backeds, Mongolians are often aggressive too. They sit in wait near to eagles on the Han River, and on multiple occasions I have seen them try to rob fish from Common Mergansers and harass groups of dabbling ducks. Here in Korea, they are often found patrolling rivers near flocks of roosting Baikal Teal, and at least a half-dozen times I have watched one swoop down to whack a hapless duck on the back of the head. I have seen this kind of aggressive behaviour only by birds that show multiple features of Mongolian Gull and never by birds showing multiple features of Vega or Taimyr Gull. And if you live and bird in eastern China, you have probably seen similar behaviour too, right?

VEGA GULL: NORTHEAST ASIAN BREEDER

Adult Vega Gull Larus vegae, March 6th 2017, Kosong County, DPR Korea. Even in March, this individual is far from acquiring breeding plumage. Note the heavily marked head, with this dense brown-grey hood extending down to the breast; the pale-based bill; and the tiny white tips to some of the primaries, suggesting that this individual is still undergoing primary moult.

Caption and photo by Nial Moores.

The third of these Herring-type gulls is Vega Gull. From experience in Korea and southwestern Japan, I would be surprised if birders could find many Vega in a muddy river-mouth in Shanghai–especially on a date as late as mid-March. For at least on this side of the Yellow Sea, the Vega Gull is much more a species of fishing harbours, mariculture platforms, and sandy beaches. They do occasionally show up on rivers, but they are primarily a coastal species, strongly associated with, and perhaps now even dependent on, human fisheries when away from the breeding grounds. Much of their breeding range lies to the far northeast of Asia, not to the west or northwest. As a result, their migration and moult appear to be more staggered than that of Taimyr or Mongolian Gulls. After all, they have the option of remaining close to the coast and to fishing harbours along most of their migration route, with the potential to stop off en route to feed when they need to. This is presumably one reason why there are not so many Vega left in the Yellow Sea by mid-March. Many have already migrated out of the Yellow Sea and through the Korean Strait past Busan in early March, with much of the return migration back into the Yellow Sea in November (when thousands can be seen around fishing boats) and in December.

It is not only habitat and behaviour that helps in the identification of Vega Gull. Most adults are easy to pick out from Taimyr and Mongolian in mid-winter: sloping-backed and rather weaker looking than Mongolian; pink-legged and with pale yellow bill bases; dirty grey upperparts lacking slate tones; often heavily streaked and mottled on the head and down the breast sides. The ones easiest to ID also have a nice and distinctive primary pattern–showing a weak string of pearls and a more jagged edge of grey, black, and white than in Slaty-backed Gull. If you find a juvenile or immature gull in this region that looks pretty much like an American or European Herring Gull, then the chances are very high that it is a Vega.

Much is still to be learned, of course. But from what we can see in this region Taimyr, Mongolian, and Vega Gulls have their own preferred ecological niches; their own migration phenology and moult timing; and their own plumage characters and distinctive bare-part coloration. It also seems very likely that they have their own distinctive vocalisations, too. They also have distinct, separate breeding areas. And yet despite this, all three remain stuck in taxonomic controversy. The IOC does not list taimyrensis, for example, and UK-based BirdLife International (2017) recently even went the extra step and lumped Mongolian, Taimyr, Vega, and American Herring Gull into a single species, which they then named Arctic Herring Gull Larus smithsonianus (this seems worth repeating: a species that nests as far south as the Yellow Sea is now called Arctic Herring Gull by the world’s premier bird-conservation organisation).

A PAUCITY OF RESEARCH

The lack of understanding of these Asian gulls in Europe and North America is in large part owing to a paucity of research. Most of these gulls migrate huge distances between areas that are very hard to travel to for logistical and geopolitical reasons, and most of the research that has been done on them is not published in English or in peer-reviewed journals. Some of the problem also likely comes from gull experts based in Europe and North America then trying to make what little evidence they can access on these taxa to conform neatly to perceived counterpart European and North American species– taxa that are now pretty well-known after decades of study. This to me seems to be a major reason for the IOC’s inconsistency as well as BirdLife’s peculiar decision. By this I mean, this is why the IOC currently recognises the European Herring Gull, the American Herring Gull, and the Caspian Gull as three separate species, while not recognizing Taimyr Gull at all, and while also treating heuglini as a subspecies of Lesser Black-backed Gull and mongolicus as a subspecies of Vega. A more consistent approach might perhaps be instead to lump all Herring-types together; or to split all of the Herring-types apart when there is evidence to support it. All Birds Korea materials depend on the excellent recommendations of Gill and Donsker (2017) and the IOC Checklist–but not in the case of these gulls. To do so would require ignoring what appear to be consistent differences shown by these three taxa which are easily observable within this region.

Much still does need to be learned about these gulls, of course, whatever list you decide to follow and however you choose to organise your observations. Without doubt though, Mongolian, Vega, and Taimyr Gulls are a major part of the coastal birding experience in East Asia, and they offer great potential for pushing the frontiers of ID. It would therefore be very helpful for more birders to spend time on these and other gulls–looking for wing tags and bands, documenting moult progression with photographs, and generating ever-better information on this group of fascinating and under-appreciated birds.

Your Handy-Dandy Nordmann’s Greenshank ID Primer!

Distinguishing non-breeding Nordmann’s Greenshank from Common Greenshank is a tricky task, but one that reaps rewards. With practice you too can feel the rush that comes when you realize that the greenshank you are viewing is not one of the most common shorebirds in Eurasia, but one of the rarest. On Sat. 17 Sept. 2016 at Nanhui, our team experienced that thrill, picking out a Nordmann’s in a roost holding a few hundred shorebirds.

We noted the following:

— Tibiae of Nordmann’s Greenshank are noticeably shorter than those of Common Greenshank.

Nordmann's Greenshank (L) has an appreciably higher 'knee' than the longer- and thinner-legged Common Greenshank (R). Both photos taken by Craig Brelsford in Yangkou, Rudong, Jiangsu in October 2014 (Nordmann's) and May 2011 (Common).

The picture above makes it clear. The biggest reason Nordmann’s is known as the stockier bird, the rugby player compared to the ballerina that is Common Greenshank, is tibia and leg length.

— Nordmann’s has a thicker neck that it often holds closer to its body and has a pronounced ventral angle (protruding belly), giving Nordmann’s a more hunched appearance than Common.

The larger head and thicker neck of Nordmann's (top) give it a more hunched appearance than the more graceful Common (bottom).

As with many of the characters of these species, the hunched stance of Nordmann’s is not always obvious, especially when the bird is active. Likewise, even a Common sometimes can appear stout. But as one’s observation time grows, the classic features of both species will emerge.

Nordmann’s has a thicker, more obviously bi-colored bill than Common.

As is the case with the legs, the bill of Nordmann's (top) is thicker than the bill of Common (bottom). The more obviously bi-colored bill of Nordmann's is yellow at the base.

Because the Nordmann’s at our Nanhui roost did not fly, we missed the following key characteristics:

The toes of Nordmann’s project just beyond the tail-tip; the toes of Common project farther.

With its shorter legs, Nordmann's Greenshank (top) shows just a bit of toe projection. The longer-legged Common Greenshank (bottom) shows more.
With its shorter legs, Nordmann’s (top) shows just a bit of toe projection. The longer-legged Common (bottom) shows more. Both photos taken by Craig Brelsford at Yangkou. Photo of Nordmann’s taken October 2014; photo of Common Greenshank May 2010.

This difference can be subtle, and a good camera is sometimes needed to appreciate it. But it is consistent.

Nordmann’s has a cleaner tail and underwing than Common.

The tail and underwing of Nordmann's Greenshank are clean white (panels 1, 2). The tail and underwing of Common Greenshank are streakier (3, 4). All photos in this section taken by Craig Brelsford in <a href="http://www.shanghaibirding.com/sites/yangkou/" target="_blank">Yangkou</a>, Rudong, Jiangsu in May 2011, May 2014, and October 2014.
The tail and underwing of Nordmann’s are clean white (panels 1, 2). The tail and underwing of Common are browner (3, 4). Photo info same as preceding.

Even if your Nordmann’s is roosting, you can sometimes note the white underwing. Wait for the bird to stretch out its wing.

Other differences

The calls of Nordmann’s Greenshank and Common Greenshank are markedly different. The well-known “chew-chew-chew” call of Common is never made by Nordmann’s.

In breeding plumage the species are more readily distinguishable. Nordmann’s Greenshank is also known as Spotted Greenshank for good reason. The heavily spotted underparts of breeding Nordmann’s are diagnostic. Unfortunately for birders in Shanghai, however, Nordmann’s in full breeding plumage is rarely seen.

Nordmann’s Greenshank Tringa guttifer is an endangered species. Only 500 to 1,000 of these birds are thought to remain. Development along the East Asian coast is the main reason for its decline. Nordmann’s breeds in Russia, passes through China, and winters in Southeast Asia. It is present in the Shanghai area for several months each year.

OTHER GOOD STUFF

The Nordmann’s took top billing on a day that saw veteran British birder Michael Grunwell, my wife Elaine Du, and me note 71 species at Nanhui, Lesser Yangshan, and the sod farm south of Pudong Airport (31.112586, 121.824742). We were joined at the roost and Nanhui microforests by the crack high-school birding team of Larry Chen, Komatsu Yasuhiko, Chi Shu, and Andy Lee.

Our Non-Nordmann highlights:

White-winged Tern

We noted 2500 at Nanhui, by far the highest number of White-winged Tern that I have seen. They made quite a spectacle, fluttering like snowflakes over the reed beds.

Common Tern

Three at the roost. Michael and I discussed whether Aleutian Tern, similar to Common Tern in winter plumage, passes through Shanghai and has been overlooked. Check for the red legs of Common; if the legs appear black, then keep investigating; you may have an Aleutian.

Ruddy Shelduck

Ruddy Shelduck is uncommon in Shanghai; I have recorded flocks at Chongming but had never seen the species at Nanhui. We saw a single Ruddy in the marshy agricultural land north of Lúcháo (芦潮; 30.851111, 121.848528).

Black-tailed Godwit, Bar-tailed Godwit, Great Knot, Red Knot, Grey-tailed Tattler

The godwits, knots, and tattlers were in the dry roost with the Nordmann’s. Every one of these species is at least near-threatened; Great Knot is endangered.

Black-winged Cuckooshrike

After the excitement with the Nordmann’s at the roost, the seven of us covered the microforests. Our teamwork paid off with a view of Black-winged Cuckooshrike, an uncommon passage migrant in Shanghai.

Japanese Paradise Flycatcher

Japanese Paradise Flycatcher Terpsiphone atrocaudata is the most numerous member of its genus to pass through the Shanghai region. Amur Paradise Flycatcher Terpsiphone incei also passes through, but in smaller numbers.
Japanese Paradise Flycatcher Terpsiphone atrocaudata is the most numerous member of its genus to pass through Shanghai. Amur Paradise Flycatcher T. incei also passes through, but in smaller numbers. I found this individual, a male, in Microforest 2 (30.926138, 121.970795). Like most male paradise flycatchers on passage in Shanghai, it was missing its spectacular elongated tail feathers.

Yet another near-threatened species, Terpsiphone atrocaudata is common on migration in Shanghai. We noted 10 on Saturday. Care must be taken to separate this species from Amur Paradise Flycatcher T. incei, which passes through Shanghai in smaller numbers. Male and female Japanese have a more extensive dark hood, extending almost to the belly, whereas that of Amur extends only to the upper breast. Consult your field guide for more differences.

On Lesser Yangshan we found Oriental Dollarbird. Our final stop was the sod farm south of Pudong International Airport, where we found 4 Pacific Golden Plover and 200 Oriental Pratincole.

Meet Kai Pflug, Nanhui’s Mr. Clean

Let’s hear it for Kai Pflug! The Shanghai-based German birder has taken it upon himself to clean up Nanhui, Shanghai’s best-known birding area. On Sun. 11 Sept. 2016, Kai hauled out two bagfuls of trash from Nanhui’s Microforest 2 (30.926138, 121.970795), and I’m proud to say my wife Elaine Du helped Kai out on Microforest 1. Kai has long been cleaning the microforests, and his work has had a big effect on those precious migrant traps.

In his car, Kai keeps six pairs of tongs as well as a roll of plastic bags. Kai told me he uses tongs “to show others that it’s possible to clean up trash without getting your hands dirty!” He keeps six pairs so that others can join him in his quest to keep the microforests clean.

Photographers await Fairy Pitta on Sunday in Microforest 2.

As if his work on the trash weren’t enough, Kai further burnished his eco-credentials Sunday morning at Microforest 2. There, about 30 photographers have set up camp to photograph Fairy Pitta, a species that has been present in the tiny wood since early September. Someone had speared mealworms onto a metal hook. The hook could rip the mouth of a hungry pitta. Kai spied the hook, marched into the setup, and tore it down. In his good Chinese, the product of 12 years living in this country, Kai explained to the surprised photographers, “This isn’t good! It can kill birds.”

Kai’s actions Sunday were the backdrop to an eventful birding day. Partnering yet again with veteran British birder Michael Grunwell, Elaine and I noted 75 species. We birded the well-known coastal sites at Nanhui as well as the sod farm south of Pudong Airport. We had our first migrant bunting of the season, endangered Yellow-breasted Bunting; Himalayan Swiftlet in the skies above the Magic Parking Lot (30.882784, 121.972782); and Pechora Pipit in the wet agricultural land north of Lúcháo (芦潮; 30.851111, 121.848528).

Other goodies were Lesser Coucal catching a frog, Asian Stubtail joining Fairy Pitta at the photography setup, and season’s first Yellow-browed Warbler, Siberian Thrush, and Blue-and-white Flycatcher. We had Green Sandpiper, Grey-tailed Tattler, and a migrating flock of Red Turtle Dove near the Pechoras and Eurasian Wryneck in the recently planted trees on the inner base of the sea wall. The microforests yielded a second Fairy Pitta, 8 Black-naped Oriole, 7 Japanese Paradise Flycatcher, and a good count of 12 Siberian Blue Robin.

This Black-naped Oriole, one of eight we found Sunday at Nanhui, was in full migration mode and very hungry. A forest dweller, Black-naped Oriole is usually among the shyest of birds, but this juvenile was foraging in the open and allowed us to approach while it searched frantically for food. It even sampled a flower petal!

It even sampled a flower petal!

Our trip to the sod farm was cut short by rain. Before the shower we noted ca. 800 Oriental Pratincole. Obviously this grassy area is important to the species, which breeds in the Shanghai region and which with the development of Pudong has seen a dramatic shrinkage of its territory.

On Mon. 5 Sept. Elaine and I did our first urban birding of the season at Shanghai’s Century Park. Among the 24 species we noted were passage migrants Oriental Dollarbird, Asian Brown Flycatcher, and Grey-streaked Flycatcher.

Siberian Blue Robin, among the 12 we found Sunday in the microforests of Nanhui. In Nanhui one usually views these secretive birds from a distance and obscured by branches and leaves, as shown in the two left-hand panels. On their breeding grounds in Heilongjiang, <a href="http://www.shanghaibirding.com/explorations/boli-may-june-2016/" target="_blank">where this past spring Elaine and I studied Siberian Blue Robin and other northeast China breeders</a>, one is lucky to get even this good a view.
