Editor’s note: In recent weeks, Shanghai has had extraordinary visits by three species of crane. Since 12 Nov. 2016, 3 Siberian Crane, a Critically Endangered species, have been recorded regularly in a reclaimed area of Hengsha Island (photo above, left). On 10 Dec. 2016, Endangered Red-crowned Crane made the first recorded visit by that species to Cape Nanhui (top right). Also since 12 Nov. 2016, Vulnerable Hooded Crane has been recorded regularly at Cape Nanhui (bottom right). Before 12 Nov., Hooded Crane had never been recorded on the Shanghai Peninsula.

The appearance on 10 Dec. 2016 of 2 Red-crowned Crane at Pudong’s Cape Nanhui was more than just a historic, first-ever sighting. It was a message. The endangered cranes, as well as the Siberian Crane on Hengsha Island and Hooded Crane at Cape Nanhui, are telling us that habitat is steadily disappearing elsewhere along the Chinese coast, particularly in Jiangsu; that the habitats in Shanghai are some of the best that remain; and that those habitats require world-class protection. The most pressing need is the creation of a world-class, small to mid-sized wetland reserve at Cape Nanhui.
Errant cranes migrating along the Chinese coast may once have settled for a while somewhere in Jiangsu. Every year, however, cranes migrating along the coast of that densely populated province find fewer and fewer places suitable to them. My wife Elaine Du and I have surveyed the Jiangsu coastline from Qidong on the Yangtze River 250 km north to Yancheng National Nature Reserve. We have seen with our own eyes the dramatic transformation of the Jiangsu coast. Even areas in Jiangsu receiving considerable international attention, such as Yangkou and the coastal areas of Dongtai, are under threat.
Cape Nanhui may not seem like a first-rate natural area, but it is in better condition than almost any place I have seen between Qidong and Yancheng. I say, therefore, that the recent crane sightings in Shanghai have come about in large part because elsewhere so much has been lost. The cranes have nowhere else to go.
And that is why conserving Cape Nanhui is so important. Shanghai is facing a crisis, a “danger-opportunity” (危机). The 危 or danger is that amid the wholesale destruction of so much coastal habitat elsewhere, Shanghai will follow suit and destroy its remaining good habitat. The 机 or opportunity is for Shanghai to gather into its bosom the birds ejected from Jiangsu—to be not only the economic but also the conservationist leader on the Chinese coast. The creation at Cape Nanhui of an easily accessible, world-class, small to mid-sized wetland reserve along the lines of Sungei Buloh in Singapore would be a way of avoiding the 危 and seizing the 机.
The case for an easily accessible wetland reserve at Cape Nanhui could scarcely be more clear-cut:
(1) Cape Nanhui is of extraordinary environmental importance. The tip of the Shanghai Peninsula between the Yangtze River and Hangzhou Bay, Cape Nanhui is a stepping stone for birds migrating across those bodies of water. Cape Nanhui also holds large reed beds, habitat critical to Reed Parrotbill and other species at risk.
The 2 Red-crowned Crane this past Saturday were the latest in a parade of endangered birds that I and other birders have noted at the Cape over the years. Critically Endangered Spoon-billed Sandpiper uses Cape Nanhui, as does Endangered Nordmann’s Greenshank. Around 2 percent of the world’s Endangered Black-faced Spoonbill are dependent on Cape Nanhui for several months each year. Large reed beds remain at Cape Nanhui and are the final strongholds on the Shanghai Peninsula of Near Threatened Marsh Grassbird and Near Threatened Reed Parrotbill. The latter species, a candidate for Shanghai Provincial Bird, will virtually disappear from mainland Shanghai if the reed beds at Nanhui are destroyed.
(2) Shanghai is clearly under-performing on the conservationist front. More must be done, and a good place to begin is Cape Nanhui.
Nature reserves have been established only on the extreme fringes of the city-province (which is a third the size of Wales). There are no reserves in mainland Pudong, a giant coastal district nearly twice the size of Singapore. Nowhere in this megalopolis can residents without a car enjoy the natural side of Shanghai, a city with an extraordinarily rich natural heritage. There is no known plan to conserve any of the dozens of square kilometers of reclaimed land on Hengsha.
(3) Because it is in the back yard of Shanghai, a city-province of more than 25 million people, a well-run, easily accessible wetland reserve at Cape Nanhui could be the match to light the fire of conservation across all China.
Hundreds of thousands of children could visit the reserve with their parents using nothing more than the Metro and a quick taxi ride and be sleeping in their own bed that night, dreaming about the wild birds they had seen that day. For millions of parents and their kids, the weekend could be “Saturday, Disney; Sunday, Cape Nanhui Wetland.” A day at a Cape Nanhui Wetland would be an early introduction to the glories of natural Shanghai and would foster an appreciation of the natural world.
If Shanghai can be a world economic center and have world-class airports and a world-class skyline and world-class entertainment such as Disney, then it can and must have world-class preservation of its priceless coastline and migratory birds.
I repeat: The case for a world-class, easily accessible wetland reserve at Cape Nanhui is clear-cut.
111 SPECIES AT CORE SHANGHAI SITES
Elaine and I birded four of the eight days between 3 Dec. and 10 Dec. 2016, noting 111 species. We birded three days at Cape Nanhui, half a day on Hengsha Island, and half a day at Binjiang Forest Park in Pudong. On 10 Dec. Elaine and I led a group of members of the Shanghai Birding WeChat group on a tour of Nanhui. We birded the other days with Shanghai-based U.K. birder Michael Grunwell and U.S. birder Susan Lessner.
Major highlights were 2 Red-crowned Crane and Hooded Crane at Cape Nanhui and 3 Siberian Crane on Hengsha as well as Baikal Teal and Red-breasted Flycatcher at Nanhui and Ferruginous Duck on Hengsha.
Nanhui also gave us three-day counts of 20 Vulnerable Swan Goose, 14 Greater White-fronted Goose, 190 Tundra Swan (bewickii), 255 Common Shelduck, 11 Greater Scaup, 4 Black-necked Grebe, Brown Crake, Vulnerable Saunders’s Gull, 2 Mew Gull Larus canus, 2 Lesser Black-backed Gull (heuglini), late Eurasian Wryneck, uncommon winter visitor Dusky Warbler, 22 Near Threatened Reed Parrotbill, and 2 extralimital Common Starling.
We noted shorebird stragglers at Nanhui, among them Near Threatened Eurasian Curlew (2), Bar-tailed Godwit (1), and Red Knot (3). We recorded just 2 Endangered Black-faced Spoonbill, and we found 3 Black-collared Starling near Pudong Airport.
Hengsha gave us a rare Shanghai sighting of adult-male Hen Harrier as well as 3 Chinese Grey Shrike and impressive numbers of buntings. In a single stretch of scrub just 500 m long, we counted 14 Little Bunting, 18 Rustic Bunting, 17 Yellow-throated Bunting, 4 Black-faced Bunting, and 150 Pallas’s Reed Bunting.
Binjiang Forest Park once again proved to be one of the only places in urban Shanghai where Great Spotted Woodpecker is reliable. Thrushes were numerous, with Naumann’s Thrush leading the list.
