The Cuckoos of Shanghai

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

Large Hawk-Cuckoo breeds near Shanghai. I found this fledgling 25 June 2009 at Nanjing Botanical Garden. It was being raised by Masked Laughingthrush Garrulax perspicillatus. (Craig Brelsford)

The non-Cuculus parasitic cuckoo that one is most likely to see in Shanghai is Large Hawk-Cuckoo Hierococcyx 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.

Hawk-cuckoos have bills quite unlike those of the sparrowhawks that they mimic. L: Japanese Sparrowhawk. R: Large Hawk-Cuckoo. (Craig Brelsford, Kai Pflug)

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-Cuckoo Hierococcyx 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.

L: Rufous Hawk-Cuckoo (Craig Brelsford). R: Large Hawk-Cuckoo (Kai Pflug)
Adult Rufous Hawk-Cuckoo (L) shows (1) white neck-sides and nape patch, (2) white scapular crescents, and (3) a rufous border to the black subterminal band on the tail. Large Hawk-Cuckoo (R) shows none of these. L: Original Magic Forest (32.567487, 120.996980), Yangkou (Rudong), Jiangsu, 15 Sept. 2012 (Craig Brelsford). R: Cape Nanhui, Shanghai, April 2017 (Kai Pflug).

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.

Rufous Hawk-Cuckoo Hierococcyx hyperythrus. The lack of rufous wash on the breast and belly suggests that this is a juvenile. The grey streaking of the adult plumage has appeared. Also visible are the white nape patch and scapular crescents as well as the rufous bands on the tail. Original Magic Forest (32.567487, 120.996980), Yangkou (Rudong), Jiangsu, 6 Oct. 2010. (Craig Brelsford)

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

L: Asian Koel, female, 2 June 2016, Nanhui, Shanghai (Kai Pflug). R: Asian Koel, male, 17 May 2015, Dongtai, Jiangsu (Craig Brelsford).

Eudynamys scolopaceus chinensis is the northernmost-breeding race among the koels, a small, mainly tropical group.

The other non-Cuculus parasitic cuckoos of the Shanghai region are Asian Koel Eudynamys scolopaceus and Chestnut-winged Cuckoo Clamator coromandus. Neither offers 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.

The parasitic cuckoos are secretive and most conspicuous by sound. A poor, fleeting glimpse is all that one is likely to get. That was the case in the Tianmu Mountains with this Chestnut-winged Cuckoo. (Craig Brelsford)
The parasitic cuckoos are secretive and most conspicuous by sound. In the Tianmu Mountains (30.344148, 119.440201) on 10 May 2015, this poor, fleeting glimpse was all I could manage of this Chestnut-winged Cuckoo. Its presence was more than made known, however, by its piercing whistle and harsh cries. (Craig Brelsford)

I have yet to see Chestnut-winged Cuckoo in Shanghai. It has been noted at Tongshan Forest Park (32.348637, 119.106915) in Yangzhou, Jiangsu, and I have noted it at Laoshan (32.071265, 118.560699) in Nanjing as well as in Zhejiang in the Tianmu Mountains (30.344148, 119.440201). With its glossy-black erectile crest, rufous wings, and long, black tail, the species is unmistakable–if you can manage to see it.

SHANGHAI-AREA CUCULUS CUCKOOS

Five Cuculus cuckoos have been claimed for Shanghai: Lesser Cuckoo Cuculus poliocephalus, Indian Cuckoo C. micropterus, Himalayan Cuckoo C. saturatus, Oriental Cuckoo C. optatus, and Common Cuckoo C. 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.

Common Cuckoo (L) is the size of a sparrowhawk and is appreciably larger than the thrush-sized Lesser Cuckoo (R). Himalayan Cuckoo is on average smaller than Common, but the size difference is more difficult to appreciate. L: Nanhui. M: Foping, Shaanxi. R: Old Erlang Road, Sichuan. (Craig Brelsford)

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.

Juvenile <em>Cuculus</em> cuckoos are very difficult to ID to species. This is especially true in Shanghai, where almost all <em>Cuculus</em> cuckoos are passage migrants. If however you are on the breeding grounds and know a little about the host species, then you may be able to attempt an ID. In this photo, taken 22 July 2010 at Balangshan (<a href="https://www.google.com/maps/place/30%C2%B057'39.5%22N+102%C2%B052'42.2%22E/@30.960977,102.7383223,11z/data=!4m5!3m4!1s0x0:0x0!8m2!3d30.960977!4d102.878398" target="_blank">30.960977, 102.878398</a>) in <a href="https://www.google.com/maps/place/Sichuan,+China/@30.1028528,93.9726458,5z/data=!4m5!3m4!1s0x36e4e73368bdcdb3:0xde8f7ccf8f99feb9!8m2!3d30.651226!4d104.075881" target="_blank">Sichuan</a>, the juvenile cuckoo that the Rosy Pipit is feeding is most likely Common Cuckoo. The hugeness of the cuckoo is a clue, but the strongest indicator may be the foster parent. Common Cuckoo is known to parasitize the nests of pipits, while Himalayan Cuckoo and Lesser Cuckoo favor small warblers and Indian Cuckoo favors drongos and shrikes. (Craig Brelsford)

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.

NON-CUCULINAE CUCKOOS

Lesser Coucal Centropus 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 Coucal Centropus 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.

EASTERN CROWNED WARBLER SINGING IN SHANGHAI

Eastern Crowned Warbler, 30 Sept. 2014, Yangkou (Rudong), Jiangsu. One of the Big 5 Leaf Warblers of ShanghaiPhylloscopus coronatus is a common autumn and spring passage migrant in Shanghai. It is usually silent in Shanghai, but on 15 April 2017, I heard one sing in Century Park. Migrating birds often sing snatches of song far from their breeding grounds. On 7 April 2016, also at Century Park, I heard White’s Thrush sing. (Craig Brelsford)

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. Elaine and I have birded Boli on three occasions, most recently in May-June 2016.

We were in the heavily wooded area near Gate 7 when I heard the wheezy song. It sounded just like this recording I made in Heilongjiang:

Eastern Crowned Warbler Phylloscopus coronatus, 2 June 2016, Xidaquan National Forest (45.727751, 130.317316), Boli, Heilongjiang (00:03; 922 KB)

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.

All 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.

Studying Northeast China Woodland Birds in Elaine’s Hometown

From 26 May 2016 to last Sunday (12 June), Elaine Du and I were in her home village of Dawucun in Boli County, Heilongjiang. We birded 15 of those days, mainly around Xidaquan National Forest, and noted 84 species. Our bird of the trip was Band-bellied Crake, and we found breeding Eurasian Eagle-Owl. We noted in full breeding mode many birds that we had previously known only as passage migrants in Shanghai; we enjoyed for the first time the songs of Siberian Blue Robin, Blue-and-white Flycatcher, White-throated Rock Thrush, Siberian Thrush, and many other species.

In this post, you will get an introduction to Boli and eastern Heilongjiang, you will discover the birds we met up there at the height of the breeding season, you will learn about the birds we missed, and you will find out how Elaine and I combine birding with family. There are as well 31 of my sound-recordings of Boli birds and plenty of photos.

For the full report on our spring 2016 trip, including daily lists and a master list detailing where and when we encountered each species, click here. For the report on Elaine’s and my first two trips together to her hometown, click here.

Why Should Birders Care about Boli?

Boli County is a good place to study the woodland birds of the eastern Palearctic. Its forests, remnants of the ancient northern temperate forest that once stretched unbroken across the region, hold northern species absent further south in China. In springtime, Boli County is the breeding home of birds that in the more densely populated southern regions of China appear only as passage migrants or winter visitors.

Background

Boli County lies within the Amur Basin of Northeast China. It is part of Qitaihe Prefecture in eastern Heilongjiang, not far from the Sino-Russian border. Map courtesy Wikipedia.

In January 2015 Elaine and I were married in Dawucun, where Elaine was born. During breaks in the festivities, I explored the frozen country. Expecting to find only magpies and sparrows, I was pleasantly surprised to find forested hills near the village and good birds such as Rough-legged Buzzard. I vowed to return and bird the area thoroughly.

In August and September 2015, Elaine and I fulfilled that goal. During a 32-day visit to her hometown, Elaine and I discovered Xidaquan National Forest, a 9,400-hectare reserve in the Laoye Mountains. Xidaquan preserves a remnant of the northern temperate forest that once covered the region. We were thoroughly impressed and made plans to bird the area yet again, this time during breeding season. The trip described here is the realization of that plan.

For Elaine and me, birding trips to Boli are special because they combine Northeast China birding with family. Elaine is never happier than when she is with her parents and two elder sisters, and I not only like her family but also appreciate the opportunity they give me to learn about Chinese culture.

Like many residents of the Northeast, Elaine is descended from migrants who chuǎng Guāndōng (闯关东)–“leapt” north, mainly from Hebei and Shandong, to farm areas of Guandong (Manchuria) formerly closed to Han Chinese settlement. In Elaine’s case, the settlers were her parents, who left Shandong in the 1970s.

The settlement of the Northeast by Han farmers is a major event in Chinese history, like the settling of the West is to Americans. The transformation the migration has wrought on the land has been profound. In eastern Heilongjiang, the toil of thousands of farmers has converted the land from an endless forest into a vast maize field. Where tigers once roared, magpies now caw.

Amid the sea of grain fields are islands of the old Manchurian forest. One of the best is Xidaquan National Forest, just 25 km from Boli Town. After our discovery of Xidaquan in the summer of 2015, we turned it into our laboratory in which to study the birds of the eastern Palearctic woodlands. We have now spent 20 days birding in the reserve–12 days in summer 2015 and eight days in spring 2016.

Key Birds

A birder led blindfolded through southwestern Boli County in spring would be able to tell the quality of the forest by the birds he heard. The pine plantations are nearly silent. In recently cut areas where the forest has just begun to regenerate, one may hear a few Eastern Crowned Warbler, Radde’s Warbler, and Black-faced Bunting. If a layer of undergrowth has formed, then one may hear in addition to those species Thick-billed Warbler, Siberian Blue Robin, and Siberian Rubythroat. In places where most of the trees are hardwoods and have reached about 10 m in height, the sound of birdsong is constant throughout the day. Pale Thrush sing powerfully from perches hidden in the canopy, Yellow-throated Bunting sing from treetops and defend territory, Willow Tit, Coal Tit, and Japanese Tit sing their lively Parid songs, and White-throated Rock Thrush whistle in a minor key. The best places at Xidaquan are yet another cut above, being able to support the species mentioned above as well as more habitat-sensitive species such as Mandarin Duck, Rufous Hawk-Cuckoo, Lanceolated Warbler, Gray’s Grasshopper Warbler, and White’s Thrush.

The following is a list of the key birds noted by Craig Brelsford and Elaine Du in spring 2016 in Boli County.

Eurasian Eagle-Owl Bubo bubo

We found a breeding pair with two owlets nesting at the high, inaccessible reaches of the big quarry at Jiulong Reservoir, where we also spotted the species in summer 2015. The giant owls are tolerant of the traffic from the road, and at a second, smaller quarry nearby, they tolerate noise from a busy poultry farm below. The owls perch conspicuously by day and are active in the villages at night. In summer 2015, eagle-owls would perch at night on the buildings of Elaine’s parents’ farm.

Mandarin Duck Aix galericulata

Mandarin Duck atop a shed, 28 May 2016.

Deep in the forests of Xidaquan, we found Mandarin Duck in ponds no larger than a kiddie pool. This shy species was also found on the large pond near the entrance to Xidaquan, in rice paddies in the villages, and in flocks in Jiulong Reservoir. In spring 2016 we recorded this species on eight of our 15 birding days and in summer 2015 on seven of our 27 birding days. Boli County is the heart of the Northeast China breeding range of this most beautiful of ducks.

Black Woodpecker Dryocopus martius

A graceful woodpecker and one of the stars of the Northeast Chinese forest, noted by us on three days in spring 2016 and on 11 days in summer 2015.

Rufous Hawk-Cuckoo Hierococcyx hyperythrus

Noted on nine of our birding days, exclusively in the better forests around Xidaquan. Has softer version of the “Brain fever!” call of Large Hawk-Cuckoo.

Rufous Hawk-Cuckoo, Xidaquan, 2 June 2016 (01:06; 3.4 MB)

Indian Cuckoo Cuculus micropterus

Noted on eight days in Boli County in spring 2016. None of our records came from the higher-quality, higher-elevation forest deep in Xidaquan park but from the lower-quality, newer forests closer to the villages.

Oriental Cuckoo Cuculus optatus

In contrast to Indian Cuckoo, in spring 2016 most of our records of Oriental Cuckoo, spanning 13 days, came from the deep forests of Xidaquan.

Common Cuckoo Cuculus canorus

We heard the famous call of Common Cuckoo on 13 days. Most records came from open areas or from forested places near open areas.

Grey Nightjar Caprimulgus jotaka

We enjoyed pre-dawn views of this species roosting on County Road Z002 and heard its clattering call both at dawn and dusk.

Eurasian Jay Garrulus glandarius brandtii

Cinnamon-headed ssp. brandtii is a treat for birders in Northeast China (also occurs in Xinjiang). Resident and conspicuous in all seasons.

Coal Tit Periparus ater ater

If this bird looks familiar to European birders, it's because it's the same nominate race of Coal Tit found in Continental Europe. Photo taken in hills S of Boli Town on 7 June 2016.

Radde’s Warbler is a powerful singer and among the most conspicuous birds at Xidaquan National Forest.

Second only to Eastern Crowned Warbler as the most conspicuous leaf warbler, with a powerful song that belies its small size. Noted regularly in summer 2015 (10 days) and spring 2016 (12 days), mostly in the better forest and forest-edge habitat at Xidaquan.

Radde’s Warbler, Xidaquan, 30 May 2016 (02:51; 7.6 MB)

Dusky Warbler Phylloscopus fuscatus

Noted on 10 days in spring 2016 and nine in summer 2015. Has less powerful song than Radde’s, lacking trills, and unlike Radde’s avoids deep forest. Often sings from conspicuous perch in high tree.

Pale-legged Leaf Warbler Phylloscopus tenellipes

Recorded on nine days in spring 2016. Heard singing and seen defending territory. Usually found in the high canopy or middle canopy in the better sections of forest at Xidaquan. Elaine and I did not note this species in Boli in summer 2015.

Oriental Reed Warbler Acrocephalus orientalis

Oriental Reed Warbler is known to be able to use marshy habitat with woody plants rather than reeds. As reeds are rare in the areas we bird in Boli County, our Oriental Reed Warbler were found among woody plants. Found on four days in spring 2016, mainly on the shore of Jiulong Reservoir.

Oriental Reed Warbler, Jiulong Reservoir, 10 June 2016 (00:06; 1.8 MB)

Below is a recording of Siberian Thrush on a typical morning at Xidaquan. In the background you can hear Oriental Cuckoo, Common Cuckoo, Radde’s Warbler, Eastern Crowned Warbler, and Gray’s Grasshopper Warbler.

Siberian Thrush, Xidaquan, 3 June 2016 (00:51; 2.8 MB)

White’s Thrush Zoothera aurea

One of the rewards for waking early was hearing the monotonous, ventriloquial song of White’s Thrush. It normally calls unseen from deep within the forest and goes silent about an hour after sunrise. One morning Elaine and I saw this most secretive bird climb a tall tree and utter its mysterious call. The first, lower note was apparently hummed through its closed or barely open mouth, while for the high note the thrush gaped wide. At a location nearby I witnessed the ventriloquy. The low note seemed to be coming from a place to my right, while the high note seemed to be coming from a place in front of me. Only after a few minutes did I realize that a single unseen White’s Thrush was uttering both notes.

Pale Thrush Turdus pallidus

Noted on eight days in spring 2016 and five days in summer 2015. Shy. Sings powerfully from unseen perches deep in the forest. At dawn and dusk sometimes seen foraging on the roadside.

Blue-and-white Flycatcher Cyanoptila cyanomelana

We found Mark Brazil’s description of the breeding habitat to be apt: “ … in forested mountains, generally in mature mixed broadleaf forest with dense undergrowth, often near streams … ” (Birds of East Asia). Noted on eight days in spring 2016 and on two days in summer 2015.

Siberian Blue Robin Larvivora cyane

Noted on 12 days in spring 2016, with a high of 21 individuals on 2 June. Its song, delivered from deep cover, consists of a burst of sound followed by a pause and buildup then another burst, each burst distinct from the other.

Siberian Rubythroat, Xidaquan, 28 May 2016 (02:20; 6.4 MB)

Yellow-rumped Flycatcher Ficedula zanthopygia

Sings a long, slow, deliberate, and loud song somewhat like that of Blue-and-white Flycatcher. Noted on 12 days in spring 2016.

Yellow-rumped Flycatcher, hills S of Dawucun, 5 June 2016 (00:58; 3.1 MB)

White-throated Rock Thrush Monticola gularis

I learned the call of this East Asian specialty by doggedly following a bird that was singing and moving unseen in the canopy above me. Finally the secretive singer allowed me to glimpse him, and only then could I confirm that he was White-throated Rock Thrush. Noted on three days in spring 2016 and once in summer 2015.

White-throated Rock Thrush, Hongwei Linchang, 7 June 2016 (01:04; 4.1 MB)

Birds We Missed

The deep forest at Xidaquan. This seemingly stable environment shows a very different set of birds according to the season. In the area where this photo was taken, in August and September 2015 Elaine and I found Eurasian Treecreeper, Goldcrest, and Yellow-browed Warbler. We saw none of those species in May and June 2016. Pale-legged Leaf Warbler, White's Thrush, and Lanceolated Warbler were in the same area in spring 2016.

Pale-legged Leaf Warbler, White’s Thrush, and Lanceolated Warbler were in the same area in spring 2016.

The forests of Boli County change markedly from season to season. On our brief initial trip in January 2015, winter visitors such as Common Redpoll, Eurasian Bullfinch, and Pallas’s Rosefinch were scraping out a living in the snowy, barren forests. In late summer bird waves are common, in springtime virtually non-existent. Late summer shows few birds in breeding mode but offers passage migrants. In springtime the songs of breeding birds resound.

Birds seen in one season may not be seen in another. In some cases, as with Hazel Grouse, it is easy to understand why. In other cases, the reason is less clear. Other birds, such as Red-flanked Bluetail, that one would expect in the region have yet to appear on any of our lists. Here are some of the birds we missed on our spring 2016 trip.

Hazel Grouse: On our summer 2015 expedition, Elaine and I noted this species on 10 days, both in the excellent habitat of Xidaquan and in the lower-quality forest in the hills south of Dawucun. We noted no Hazel Grouse in spring 2016. The grouse were breeding and had retired to the quiet recesses of the forest with their young.

Great Spotted Woodpecker: Common in much of China, noted just once by Elaine and me in summer 2015 and not at all in spring 2016. Its congener White-backed Woodpecker is common in the area.

Eurasian Three-toed Woodpecker: Scarce species noted by us once at Xidaquan in summer 2015. Missed in spring 2016.

Rufous-bellied Woodpecker, Japanese Pygmy Woodpecker: Rufous-bellied Woodpecker ssp. subrufinus is reported in eastern Heilongjiang, as is Japanese Pygmy Woodpecker. Neither has been found by us around Boli.

Black-naped Oriole: A species yet to be noted by us in Boli.

Azure Tit: This unmistakable tit has been reported around Lake Khanka, on the Sino-Russian border east of Boli County. We have yet to see the species in Boli.

Marsh Tit: Race brevirostris noted by us on 13 days in summer 2015, zero times in spring 2016.

Manchurian Bush Warbler, Baikal Bush Warbler, Chinese Bush Warbler: Yet to be noted by us in Boli.

Asian Stubtail: Noted on four days in summer 2015, zero times in spring 2016.

Manchurian Reed Warbler: We made a point to look for this bird, paying careful attention to the Black-browed Reed Warbler we were finding. No luck.

Yellow-browed Warbler: In spring 2016 we were expecting big counts of this species, having noted it on nine days in summer 2015. We noted it not once in spring 2016. It most likely does not breed in the area and was passing through the region in August and September 2015.

Arctic Warbler: Also apparently a passage migrant at Xidaquan. In spring 2016 we had but one record of a singing individual at Xidaquan. In summer 2015 we had two records.

Two-barred Warbler: Yet another apparent passage migrant. Noted on four days in summer 2015, zero times in spring 2016.

Red-flanked Bluetail: Surprise! We have yet to record this species in Boli County.

Eurasian Treecreeper: Noted by us four times in summer 2015, zero times in spring 2016.
