Comparing Blyth’s Pipit & Richard’s Pipit

With more and more birders operating in Shanghai, more and more vagrant birds are bound to be discovered. One possibility is Blyth’s Pipit Anthus godlewskii (photo above, L), a species similar to our familiar Richard’s Pipit A. richardi (R). Blyth’s breeds mainly in Mongolia, occurs on passage in central China, and winters mainly in India, so any records here would be of extralimitals. Let’s examine here how to separate the two pipits.

Comparison of pipits
Comparison of adult-type Richard’s Pipit Anthus richardisinensis‘ (1) and adult Blyth’s Pipit A. godlewskii (4). The population group A. r. ‘sinensis’ occurs in southeast China south of the Yangtze River. Structurally, ‘sinensis‘ is the smallest group in Richard’s, with proportions recalling Blyth’s. Note however the blackish centers to the median coverts (2, 3). In adult-type Richard’s (2), the centers are triangular and tinged rufous at the edges. In adult Blyth’s (3), the centers are squarish, less rufous-tinged, and more clear-cut. 1, 2: Cape Nanhui, December. 3, 4: Hulunbeier, Inner Mongolia, July. (Craig Brelsford)

The key to getting a Blyth’s in Shanghai is paying attention to the many Richard’s Pipit that we see in the area. Anthus richardi is more or less a passage migrant in the Shanghai area and is recorded here regularly in spring and autumn. Some are present in winter; Elaine Du and I had a “sinensis” last week, the ID’ing of which led to this post.

flight song
More views of Blyth’s Pipit performing flight song, Inner Mongolia, July. In Pipits and Wagtails, Shanghai Birding member Per Alström et al. write that in flight, Blyth’s Pipit ‘often recalls one of the smaller pipits rather than Richard’s’ (237). Note however that Anthus richardi ‘sinensis,’ a population group within Richard’s Pipit often found in Shanghai, is structurally similar to Blyth’s. (Craig Brelsford)

Richard’s “sinensis” is very similar to Blyth’s, being best told by song, which is rarely heard in the Shanghai area. According to Per Alström et al., whose book Pipits and Wagtails is the authority on Palearctic and Nearctic pipits, the song of Blyth’s is “very characteristic and completely different from [that] of Richard’s” (242). During a trip in July 2015 to the Inner Mongolian prefecture of Hulunbeier, one of the few places in China where Blyth’s breeds, I recorded the song.

Blyth’s Pipit, flight song, recorded 22 July 2015 at a point (48.767866, 116.834183) near Hulun Lake, Inner Mongolia (2.1 MB; 00:32)

The calls of the two species also differ, but less markedly. The flight call of Richard’s is a common bird sound in Shanghai during migration season. The call of Blyth’s is similar enough to “cause problems even for some veteran observers” (Alström et al. 244). For Shanghai birders, even those unfamiliar with Blyth’s, a “Richard’s” with a strange flight call is worth your attention. Listen for what Alström et al. describe as a call “less harsh, softer and more nasal” than Richard’s (244). For reference, review the flight call of Richard’s:

Regarding plumage, the most reliable differentiator of Richard’s and Blyth’s is the pattern of the median coverts. In Blyth’s, a typical adult-type median covert will show well-defined, squarish black centers. In Richard’s, the adult-type median coverts are less clear-cut, rufous-tinged, and triangular. Note that the fresher the plumage, the more reliable this differentiator is.

Another less reliable criterion is structure. Shanghai birders will agree that the first impression a non-“sinensis” Richard’s usually gives is “large pipit.” Other pipits, such as Buff-bellied Pipit, Red-throated Pipit, and Olive-backed Pipit, give a “small pipit” impression.

Richard's Pipit
Richard’s Pipit, Jiangsu, September. Alström et al. urge care in ID’ing Blyth’s and Richard’s. Here, the median coverts of this Richard’s appear squarish, like Blyth’s (bottom R, inset). But note the date of the photo: September, a time of year when most Richard’s show worn plumage. ‘In worn plumage,’ the authors write, ‘the shape of the dark centres to the secondary coverts is generally less obviously different, and the pale tips can be much the same colour in both species’ (237). The ID of this Richard’s was derived from its call, a more constant characteristic, and not from the appearance of its median coverts, a more variable characteristic. (Craig Brelsford)

Alström et al. say, and I having seen Blyth’s can concur, that a birder viewing Blyth’s will get a “small pipit” impression: “The smaller size, lighter build and shorter tail,” the authors write, “are often most apparent in flight, when [Blyth’s] often recalls one of the smaller pipits rather than Richard’s.” Note also that the smaller size and shorter bill, tail, and hind claw of Blyth’s give that species a “better proportioned” look than the larger and heavier Richard’s (237).

The directions above should be seen as guidelines; individual Richard’s and Blyth’s may defy easy categorization, “sinensis” Richard’s even more so. Alström et al. caution against jumping the gun with your ID: “It is crucial to realise that in both species (especially Richard’s) appearance can vary considerably in one and the same individual depending on mood, weather, etc.,” they write. “Also, some Richard’s are structurally very like Blyth’s; this is especially true of southern Chinese Richard’s (‘sinensis’)” (237).

A record of Blyth’s Pipit in Shanghai would shoot to the top of the “Year’s Best” list. The stakes are high, so look diligently, and use caution. Good luck!

Cape Nanhui on Foot

Elaine Du and I birded Cape Nanhui on foot, noting 43 species. I had my first-ever visual record of Brown-cheeked Rail in Shanghai, and at Dishui Lake we noted Common Goldeneye, 6 Greater Scaup, and 4 Black-necked Grebe. We had an unusual winter record of Eastern Yellow Wagtail (ssp. tschutschensis).

The Brown-cheeked Rail was at 30.907690, 121.972372. Our discovery of the shy species came about because we were walking, not driving. On a sunny and unusually quiet day along Shijitang Road (the sea-wall road), Elaine and I were walking slowly, noting every sound and movement. Had we been driving, we might have missed the brief, piercing call of the rail.

The sound was coming from the reeds at the landward base of the sea wall. As it was time for lunch, and knowing how long rail vigils can take, Elaine and I sat down and ate our sandwiches in the warm sun, watching for movement in the reeds below and recording the calls the rail was intermittently making. Finally, the rail appeared atop the thin drainage canal connecting the wall to the marsh. I got a good enough look at the brownish flanks to affirm that the bird was not the extralimital Water Rail Rallus aquaticus but Brown-cheeked Rail R. indicus.

The valuable record was icing on the cake for us, because Elaine’s and my main goal today was not to acquire lifers but to get outside and exercise. If good birds appeared, we said, then fine, but nothing was more important to us than casting away the cooped-up feeling we get living in our apartment in the center city. We wanted sunshine, broad horizons, and the relatively clean air of Nanhui, and this time, for the first time, we wanted to bird Nanhui on foot.

We were able to do Nanhui without a car because of the recent opening of Metro Line 16, whose south terminus is at Dishui Lake. We needed only 90 minutes to go from our apartment near Zhongshan Park to Dishui Lake, taking Line 2 to Longyang Road and transferring to Line 16. After a quick taxi ride, by 08:15 we were at our favorite Dishui Lake viewpoint (30.908702, 121.945124). Having noted in addition to the aforementioned birds 350 Falcated Duck, 4 Tufted Duck, 1 of today’s 2 Richard’s Pipit, and surprisingly 0 Common Pochard, Elaine and I walked toward the coast. I had no camera with me, only my spotting scope and binoculars.

At the sea wall, we turned north, finding many Buff-bellied Pipit, White Wagtail, and the misplaced Eastern Yellow Wagtail. We ID’d our 2 Pied Harrier on the basis of the combination of brown back, greyish secondaries, and white rump of both birds, which were together. We heard two more rails but in even thicker cover than the first; we did not wait around for a visual to nail the ID, but we presume that they too were Brown-cheeked. Walking on an unpaved road into the reeds, we startled Common Snipe and Eurasian Teal. We watched Reed Parrotbill pry open the reed stems, making a crunchy sound.

One snipe, a loner, made only a quick, low flight before dropping stonelike and silently into the reeds. There was no “sneeze” at takeoff, unlike Common Snipe, and I saw no white trailing edge to the wing (which is not to say it was not there). The snipe appeared smaller than Common. Because of the angle of the snipe’s head as it dropped, I could not see the bill. Was it Jack Snipe? I do not know, but I urge local birders not to chalk up every snipe they see to Common but to take a good, hard look.

We u-turned and walked south, reaching the bus stop behind the Magic Parking Lot at the Holiday Inn. It was 15:20 and we had walked 17 km. We took the bus back to the Dishui Lake Metro Station. The subway ride back to Zhongshan Park was just as smooth as the ride out.
