Editor’s note: Hangzhou Botanical Gardens and the Tianmu Mountains are must-see destinations for Shanghai birders, especially those of us new to birding in southeast China. Hangzhou Botanical combines ease of access (it can be visited in a day on the bullet train) with the chance to see southeast China birds whose ranges do not reach Shanghai. Visiting the Tianmu Mountains or Tianmushan is more of a project than visiting Hangzhou Botanical, but the rewards are greater. No place so close to Shanghai offers as much high-quality mountain forest as Tianmu.
In this guest post, Shanghai birder Larry Chen tells us about his recent trip to Hangzhou Botanical and Tianmu. — Craig Brelsford
Komatsu Yasuhiko, Zeng Qiongyu, and I covered Tianmushan 6-8 July 2017. We hiked up to around 1500 meters above sea level and explored some beautiful top-quality mixed forest, including stands of the magnificent Japanese Cedar Cryptomeria japonica and Huangshan Pine Pinus hwangshanensis, as well as roadside mixed deciduous, conifer, and bamboo forest.
Some of the avian highlights from our three-day trip were the diminutive and bamboo-loving Short-tailed ParrotbillNeosuthora davidiana, Moustached LaughingthrushGarrulax cineraceus, and the regal Black EagleIctinaetus malaiensis.
The weather at Tianmu, unlike hot and humid Shanghai, was humid but relatively cool, and plenty of shade was provided by the extensive foliage.
Hiko and I visited Hangzhou Botanical on 5 July, managing to find, despite the heat, several species whose ranges do not quite reach Shanghai, among them Asian Barred OwletGlaucidium cuculoides, Grey TreepieDendrocitta formosae, and Red-billed Blue MagpieUrocissa erythroryncha.
I recommend Tianmu and Hangzhou Botanical to anyone seeking a few days’ trip out of Shanghai. Tianmushan has some beautiful habitat, comfortable but cheap accommodations, and a truly under-watched avian diversity.
We had 65 species at Hangzhou Botanical and Tianmu. Highlights:
Editor’s note: The image above shows three cuckoos of the Shanghai region. Clockwise from L: Rufous Hawk-Cuckoo, Chestnut-winged Cuckoo, and Large Hawk-Cuckoo. Join us as we study the rich array of cuckoos that passes through Earth’s greatest city.
It is spring, and one of the most thrilling moments of the bird migration in Shanghai is upon us–the passage of the Cuculinae, the Old World brood-parasitic cuckoos. Nowhere in the world is the diversity of this group greater than in eastern Eurasia, and here in Shanghai we get an enviable selection. Let us examine our Shanghai-area parasitic cuckoos and learn how to tell them apart.
We can divide the Shanghai-area brood-parasitic cuckoos into two categories: the mainly grey, slender-bodied Cuculus cuckoos and the non-Cuculus cuckoos. We will look at the non-Cuculus cuckoos first.
MASTER MIMICS: THE HAWK-CUCKOOS
The non-Cuculus parasitic cuckoo that one is most likely to see in Shanghai is Large Hawk-CuckooHierococcyx sparverioides. In the microforests at Cape Nanhui and once, to my surprise, in inner-city Zhongshan Park, I have heard the scream of “Brain fever!” The species breeds in nearby Jiangsu and Zhejiang.
The hawk-cuckoos mimic sparrowhawks, an amazing feat of evolution. The resemblance serves, scientists say, not to increase stealth but to decrease it. Passerines, mistaking the intruder for a sparrowhawk, mob it, thereby giving away the location of their nest. After the tumult dies down, the hawk-cuckoo quietly swoops in and lays her egg.
When it comes to the business of eating, however, the masquerade ends. The hooked bill of a sparrowhawk is a butcher’s tool, made for stripping the flesh of vertebrates from bone. The bill of a hawk-cuckoo is blunt, the utensil of a caterpillar-eater. Need a quick differentiator between “sprock” and hawk-cuckoo? Look to the bill.
Another separation we Shanghai birders need to make is that between Large Hawk-Cuckoo and Rufous Hawk-CuckooHierococcyx hyperythrus. If seen clearly, adult Large Hawk-Cuckoo and Rufous Hawk-Cuckoo are readily separable. Rufous Hawk-Cuckoo shows a belly washed rufous with faint streaks. Large Hawk-Cuckoo is heavily barred and streaked and has the rufous coloring confined to the upper breast.
Adult Rufous Hawk-Cuckoo shows a white spot on the nape, white neck-sides, and white scapular crescents. These features may also be visible in sub-adult Rufous Hawk-Cuckoo. Large Hawk-Cuckoo shows none of these in any plumage.
Size differences may be appreciable. An average Large Hawk-Cuckoo is 15 percent larger than Rufous Hawk-Cuckoo. The tails differ, with the black subterminal band of Rufous Hawk-Cuckoo being bordered by a rufous line above and by the rufous tail-tip below. These rufous areas may be visible in immature cuckoos.
ASIAN KOEL AND CHESTNUT-WINGED CUCKOO
The other non-Cuculus parasitic cuckoos of the Shanghai region are Asian KoelEudynamys scolopaceus and Chestnut-winged CuckooClamator coromandus. Neither poses great ID challenges.
In China, Asian Koel ssp. chinensis breeds mainly south of the Yangtze River. With its familiar “koh-EL” song, Asian Koel is as easy to hear as it is hard to see in the dense forests where it is almost invariably found. It shows strong sexual dimorphism, with the male entirely glossy bluish-black and the female brown with whitish streaks, bars, and spots.
Five Cuculus cuckoos have been claimed for Shanghai: Lesser CuckooCuculus poliocephalus, Indian CuckooC. micropterus, Himalayan CuckooC. saturatus, Oriental CuckooC. optatus, and Common CuckooC. canorus.
The latter breeds in the area, parasitizing the nests of Oriental Reed Warbler in the reed beds at Cape Nanhui. Its famous song, perhaps the best-known bird sound in the world, is hard to miss at Nanhui in May.
Lesser Cuckoo and Indian Cuckoo breed in the region and are recorded on passage in Shanghai. Himalayan Cuckoo and Oriental Cuckoo may pass through Shanghai, but inasmuch as in size, plumage, and bare parts they are nearly identical to each other and very close to Common Cuckoo, and because they rarely (if ever) sing in our region, it is impossible to know how common they are.
Hear the song of any of these Cuculus, and you will have your ID; even the similar songs of Himalayan and Oriental are readily separable. If your cuckoo is silent, however, then you will need a closer look. Lesser Cuckoo and Indian Cuckoo have a brown iris, Common a bright-yellow iris. Lesser Cuckoo is the size of a thrush; Indian Cuckoo is a third larger; Common Cuckoo is larger still, approaching the size of a female Eurasian Sparrowhawk.
In autumn, juveniles pass through Shanghai. They are silent and nearly impossible to identify to species. If one gets a close look at juvenile Lesser Cuckoo, however, one may appreciate its thrush-like size. If you happen to be on the breeding grounds, then you can attempt an ID according to the species of the foster parent.
Lesser CoucalCentropus bengalensis is the good guy of the Shanghai cuckoo world. Unlike all the other cuckoos recorded in Shanghai, but like most of the cuckoos in the world, the coucals are not brood parasites. Lesser Coucal, resident in Shanghai, builds a dome nest on the ground.
Lesser Coucal may be the only non-Cuculinae cuckoo in Shanghai, but it shares at least one trait with the brood parasites: It is very unobtrusive. Look for Lesser Coucal in areas of thick vegetation near water, such as the strips of reed bed along the canals at Cape Nanhui. If you find one, count yourself lucky.
Greater CoucalCentropus sinensis occurs south of our region. It is nearly half again as large as Lesser Coucal and has a cleaner and glossier mantle, a thicker bill, and a redder iris.

The Sounds of Shanghai’s Cuckoos, by Craig Brelsford
All cuckoos from the Shanghai area are covered here. I make my recordings with my handy little Olympus DM-650.
In this post I used several of Kai Pflug’s bird images. Kai and I have worked together from the earliest days of shanghaibirding.com, and I have published dozens of Kai’s photographs on this site. Kai made a notable contribution to my October 2016 post “ID Workshop: Paradise Flycatchers.” In September 2016 I wrote about Kai’s work cleaning up the litter at Nanhui.
Kai is from Germany, lives in Shanghai, and is an active member of the Shanghai Birding WeChat group.
Thanks also to Shanghai Birding member Jonathan Martinez for his advice on Fork-tailed Drongo-Cuckoo and Plaintive Cuckoo.

In Shanghai, the best birding occurs on the coast, 80 km from the city center. Getting there can be a chore. Birding Pudong’s Century Park, by contrast, only requires a ride on Metro Line 2. Your day list from Century will only be about a third as long as a list from Cape Nanhui, but good birding can occur there, and at little cost.
On Sat. 15 April 2017, my partners Larry Chen, Komatsu Yasuhiko (“Hiko”), Hiko’s biology teacher Zeng Qiongyu, and I had a bout of good birding at Century Park.
I had never heard Eastern Crowned Warbler sing in Shanghai. I am however very familiar with the song, because in my wife Elaine Du’s hometown of Boli, Heilongjiang, the song of Eastern Crowned Warbler is one of the most common sounds in the remnant Manchurian forest.
We were in the heavily wooded area near Gate 7 when I heard the wheezy song. It sounded like this recording I made in Heilongjiang:
It was just a snatch of song, and it occurred but once. I knew immediately that it was Eastern Crowned Warbler. The song was coming from the surprisingly high canopy of the wood.
The four of us strained to find the bird. The sun shone brightly through the canopy and into our eyes. Finally, Hiko saw movement. Through the glare we focused in and got a clear view of Eastern Crowned.
It was a shot of birding as good and satisfying as I get anywhere. And it just goes to show–good birding can occur anywhere, even in a busy city park.
On Sat. 8 April 2017 I birded Cape Nanhui with John MacKinnon. John is co-author of A Field Guide to the Birds of China, the most influential book ever written about China’s birds. On John’s first visit to the tip of the Shanghai Peninsula, we noted 84 species. John and I were joined by veteran birders Michael Grunwell and Russell Boyman and the outstanding high-school birder Larry Chen.
We gave John the Grand Nanhui Tour, starting at Luchao to the south and ending 30 km north at Binhai. Heading back to the city, we made a brief stop at the sod farm just south of Pudong Airport, where we found a single Oriental Plover.
Nanhui yielded 23 Marsh Grassbird performing the song flight at three locations, and we saw 10 EndangeredGreat Knot and 1 Near ThreatenedCurlew Sandpiper. We had a pair of Rufous-faced Warbler and a Common Starling.
Also: Garganey 57, Greater Scaup 1 (Dishui Lake), Little Curlew 31 (flock), Sharp-tailed Sandpiper 11 (first of season), Red-necked Stint 1 (first of season), Wood Sandpiper 1 (first of season), Peregrine Falcon 1, Dusky Warbler 1 at Magic Parking Lot (possibly wintered there), and Reed Parrotbill 18.
GETTING TO KNOW JOHN MACKINNON
Our partner, John MacKinnon, co-authored A Field Guide to the Birds of China. Published in 2000, the book has sold more than 50,000 copies and remains the only bird guide in English covering all China. John also wrote the first and second guest posts in the history of shanghaibirding.com.
John is witty and a fine storyteller. He had us roaring with tales drawn from his six decades as a researcher in Asia. The funniest story was about the doctor back home in Britain. Every time John straggled in, the doc would call in his students, so that they could study the strange new tropical disease John had contracted.
“I never cared about my health, because I never expected to live this long!” John said.
John also talked about his masterpiece, A Field Guide to the Birds of China.
It is difficult to overestimate the importance of the Field Guide. Had it merely been a window for Westerners to the birds of the world’s most populous country, then John’s work would have been important enough. The Field Guide, however, in translated form has introduced tens of thousands of Chinese to the birds of their own country. John’s Chinese name, Mǎjìngnéng (马敬能), is known by every birder in China.
John faced obstacles unknown to field-guide writers in North America and Western Europe, where birding has been practiced for 200 years. His sources were often thin, he said.
“For range maps, I had nearly nothing from Russia,” John said. “A Chinese book had ranges stopping at the Chinese border. Another book had no paintings, only descriptions.”
To critics who unfairly compare John’s Field Guide to field guides covering more developed parts of the world, John had this to say:
“You’ve got to finish something. We finished the book. We could have waited and said, ‘Oh, another species has been split, we must revise,’ but at a certain point you have to say, ‘We must go with what we’ve got.’”
To this day, no Westerner has repeated John’s feat. Others talked; John acted. One can imagine the feeling of accomplishment in John’s heart.
John is a handy photographer and got off some good shots, three of which are displayed in the Day List at the bottom of this post. Here are some photos I took of the pioneer birder and naturalist.
MARSH GRASSBIRD ON THE BRINK
Marsh Grassbird were singing in the large reed beds at Nanhui. They were most conspicuous at the reed bed south of the Holiday Inn (30.870711, 121.942976). The species, listed as Near Threatened by IUCN, was also noted in the pristine reed bed (30.931790, 121.949169) associated with the defunct wetland reserve.
The reed beds at Cape Nanhui may be the last stronghold of Locustella pryeri sinensis on the Shanghai Peninsula. The species is highly dependent on large reed beds. In areas where only strips of reeds remain, the song of Marsh Grassbird is never heard. Its partner species, Reed Parrotbill, a candidate for official bird of the city-province of Shanghai, is only slightly less dependent on large reed beds.
One of the areas where last year my partners and I noted Marsh Grassbird performing its song flight has been flattened. No song of Marsh Grassbird was heard there Saturday. A few Reed Parrotbill were calling in one of the strips of reeds left standing.
Much needs to be learned about Marsh Grassbird in Earth’s largest city. Birders, look for the fluttering song flight, and listen for this song:
Marsh Grassbird, 10 April 2016, large reed bed at 30.870711, 121.942976, Cape Nanhui, Shanghai (00:07; 1 MB)
The plight of Marsh Grassbird brings to mind the series of posts I wrote last year on the precarious environmental situation at Cape Nanhui.
Black-throated Loon and Red-throated Loon have been found at a little-birded recreational area in Pudong, and Slaty-backed Gull has appeared on the Huangpu River across from the Bund. All three species are rare in Earth’s Greatest City, with Black-throated Loon the scarcest. All three were brought to light by Shanghai birders using social media.
The loons had been sighted numerous times before my partner Michael Grunwell and I arrived on Sat. 18 March 2017 at Sanjiagang Seaside Park (31.217928, 121.768172). The dilapidated recreation area is on the coast of the East China Sea, near the mouth of the Yangtze River, 9 km north of Pudong Airport. Chinese birders discovered the loons, and birder Larry Chen, his partners Komatsu Yasuhiko and Archie Jiang, and bird photographer Kai Pflug followed up, reporting back to our chat group, Shanghai Birding.
On Sun. 19 March, the Red-throated Loon was discovered dead at the park by local birder Suōyǔ Hè (蓑羽鹤). It is not clear what killed the bird, but it may have slowly poisoned itself by ingesting oil that had collected on its feathers. Larry said that during his encounters with the individual “The loon was constantly attempting to preen itself” and that he clearly saw oil on one of its flanks. Can you detect anything amiss in the video below?
Red-throated Loon breeds at latitudes above 50 degrees in Eurasia and North America. Wintering Gavia stellata is more common in Shanghai than Black-throated Loon, being recorded annually here. Michael, my wife Elaine Du, and I found Red-throated Loon at Cape Nanhui in January 2016.
Black-throated Loon is also known as Black-throated Diver and Arctic Loon. Gavia arctica breeds across northern Eurasia and into Alaska. It is an uncommon winter visitor all along the coast of China and is very rarely noted in Shanghai, with the last previous record in 2012. Before the encounter Saturday, I had seen Black-throated Loon only once, on 18 Sept. 2013 at Laotieshan (38.730483, 121.134018) in the northeastern province of Liaoning.
Here is video of Black-throated Loon at Sanjiagang Seaside Park.
GULLING WITH BIRDERS IN MY POCKET
On Sat. 18 March at Binjiang Park (31.2356935, 121.4973863), with the Pudong skyline looming behind, Michael Grunwell and I scanned the gulls on the Huangpu River.
“I think we’ve found Slaty-backed!” Michael cried.
With my iPhone I took photos of the gull through my scope and uploaded the photos to Shanghai Birding, the chat group I manage on the instant-messaging application WeChat. Within minutes the experts in my pocket started weighing in. Shenzhen birder Jonathan Martinez and Larry Chen, both strong gullers, confirmed Michael’s ID. Michael and I had a life bird!
Slaty-backed Gull Larus schistisagus breeds on islands and cliffs on the coast of the Russian Far East (particularly the Kamchatka Peninsula) as well as Hokkaido. Wintering Slaty-backed are common in Japan, less common in northern coastal China, and rare in Shanghai.
