Introduction

Northwest Vietnam is a mosaic of high mountains and deep valleys, geologically an extension of the southeastern Himalayas. Temperate and subtropical ecological communities converge, varying with altitude, topography and land use, in complex, interwoven patterns. The result is a stunning diversity of birds and other organisms occupying a comparatively small, remote area. Aside from occasional visits by sport-birding groups, very little ornithology has been done in the region since the French colonial days (for a general review, see Sterling, E. et. al. 2006. Vietnam A Natural History. Yale University Press, New Haven, USA. pp.157-209).

Cloud Forest, Triple B Road. @ 1,950m, Mu Cang Chai, Vietnam, 14 December 2022 Callyn Yorke

Glenn Morris, Marc Choisy and I, joined Le Quy Minh for a four-day excursion into the Mu Cang Chai mountains of northwest Vietnam. Minh, the co-author of Birds of Vietnam, 2018, Lynx Edicions, and who has extensive field experience throughout the region, was our tour leader. His knowledge of Vietnamese birds and natural history is second to none. Indeed, our final bird list for the trip was significantly enhanced as a result of Minh’s expertise and assistance in the field.

Our winged adventure began in HaNoi. Marc, Glenn and I were a little late arriving by air from Da Lat. For some reason, the initial touch-down at the HaNoi airport was aborted, alarmingly, when only about 30 m above the runway. The Airbus 321 suddenly accelerated and gained altitude, as we watched the airfield disappear below us. The cabin PA system went silent. Everyone remained secured in their seats, still prepared for a landing of some sort. We proceeded northward for about fifteen minutes, then circled back and made a second approach with a successful landing. That was certainly a relief, though quite a few passengers apparently hadn’t noticed the unusual event. I’m fairly certain that Vietnam Airlines intended for things to stay that way.

Quy Minh had been waiting inside the airport, watching our plane coming in. He said that there were no other planes or obstructions visible on the runway during the two landing approaches. When I subsequently inquired about the aborted initial landing, the flight crew insisted it was due to “an unusually high amount of air traffic.” However, that was not really the case, at least according to what Minh witnessed.

A more likely explanation would be mechanical malfunction, pilot error, or a combination of both. When there is a problem with traffic, or foul weather (current conditions in HaNoi were fair and warm) the usual procedure is to maintain a safe distance from of the airfield, fly around and wait for landing clearance from the tower. Whatever the actual reason was for the failed initial landing of VN 1572 on December 12, 2022, the airline kept a lid on it.

Whiskered Yuhina (Yuhina flavicollis) Mu Cang Chai, Vietnam 14 December 2022 Callyn Yorke

The seven-hour drive from Ha-Noi to Mu Cang Chai included a 30-minute lunch break at a highway rest-stop cafe, where we were served a tasty bowl of pho, the only hot meal option. Among the first birds recorded for our trip was a pair of White Wagtail in the parking lot, representing two migratory forms that are quite possibly separate species (Chinese and Black-backed). We continued westward on the ‘new’ freeway, then on a series of secondary roads through heavily farmed mountain communities, arriving at the Mu Cang Chai Homestay after dark.

Mu Cang Chai Homestay 14 December 2022 Callyn Yorke

The owners, Khanh and his wife Lan, greeted us warmly and we were shown to our rooms. Marc and I were assigned separate hillside bungalows; Glenn and Minh stayed in the main building just above street level. Dinner was served by the host family; a meal consisting mainly of rice, boiled vegetables and meat, prepared Vietnamese style.

Our birding trip into the local mountains would begin after breakfast at 0630 hrs. (sunrise) the following morning. The relatively short, cold winter days meant that we needed to be birding almost continuously during daylight hours. We would have a picnic-style lunch in the field and return after dark to the homestay for dinner. That would be our routine for the following three days. Predominately cool, dry weather allowed us to be in the field all day, every day.

The final day of our birding trip, Friday, December 16, began by briefly surveying the gardens and hillside around the homestay, followed by a lengthier visit to the adjacent Mu Cang Chai river valley and rice paddy fields. Since we had been leaving and returning to the homestay mostly in the dark, the local neighborhood, riverbed and paddy fields were largely ignored. The latter locations, at a comparatively low elevation (900 m) produced more than a dozen new species for our bird trip list. By 0900 hrs. we were on our way back to the HaNoi, which would be another long drive, this time in daylight and with splendid views of the famous mountain terraces of Mu Cang Chai.

Materials, Methods and Survey Locations

Theory of the Bend’ (CY-2022) – When birding a roadway, productive locations are often near a bend in the road, where there is usually a significant ecological change due to topographical and/or drainage features. Triple B Road, Mu Cang Chai, Vietnam, 14 December 2022 Callyn Yorke

We used binoculars (e.g. Zeiss 10 x 42) and hand-held digital cameras with telephoto lenses (Olympus and Nikon) for field work, supplemented with cell phone cameras for general photography. Quy Minh used a powerful green laser pointer to assist us with locating birds; he was careful to aim the beam low, directing us to look a certain distance above the beam for a bird.

In an earnest effort to bring birds into view, Quy Minh frequently used playback recordings and vocal imitations of Collared Owlet, which sometimes attracted small songbirds, especially when in mixed species flocks. Additionally, he often used playback recordings of other, rather secretive bird species, e.g. Scaly-bellied Tesia, though rarely with any visible response from the birds. Often the vocalizing bird, hidden somewhere in the forest, went silent. The playback method is commonly used by bird tour guides and, depending on multiple factors, e.g. breeding season and weather, may sometimes bring birds into close proximity of the observers. When that happens, no one is complaining. Indeed, A chance to see and photograph a rare and secretive forest species, is for many birders, a once-in-a-lifetime experience. Unfortunately, regular use of playback recordings and sound imitations at popular birding sites, usually results in habituation. Once familiar with the trick, birds become silent, secretive and move away from the sound source.

Field notes and GPS data were recorded in real time, using eBird with Guru Maps Pro (MC) and a pocket notebook (CY). Elevation readings (+/- 15 m) were taken periodically with a Casio Pathfinder watch (CY), and recalibrated with GPS (MC). I recopied my field notes into a loose-leaf binder format later the same evening. Birds of uncertain identity were briefly described in writing and, if photographed, compared with reliable Internet reference images, e.g. Birds of the World, Cornell University, USA. Subsequently, I contacted a regional bird expert, Dave Sargeant, for his opinion regarding images of unidentified birds. Remaining species of undetermined identity are listed with a ? in the Annotated Bird List.

Triple B Road (TBR) @ the 21 km marker; Elevation 2,000 m, Mu Cang Chai, Vietnam 15 December 2022 Callyn Yorke

Multiple stops were made along an unnamed paved road (dubbed, “Triple B Road” — TBR — reflecting the nearly ubiquitous presence of Brown-breasted Bulbul during our surveys) from the river crossing in central Mu Cang Chai (Elev. 900 m), 22 km to the summit (Elev. 2,100 m), separating the districts of Lao Chai and Che Tao (see following map).

Viewing southwest from the summit on Triple B Road (Elev. 2,100 m), Mu Cang Chai, Vietnam 15 December 2022 Callyn Yorke

We walked along Triple B Road (TBR) and occasionally a short distance, i.e. < 200 m, on side tracks, observing and photographing birds. Highland habitats surveyed along TBR, varied from extensively terraced agricultural hillsides with patchy shrubland at the lower elevations, to mature cloud forest above about 1,700 m. Deep ravines and canyon drainages occurred throughout the area. Traffic (mostly motorbike) on TBR seemed to correlate with the ambient air temperature (8C to 15C) and cloud cover; the busiest times being during fair weather, i.e. Thursday, December 15, our final day birding TBR. Driving this narrow mountain road was occasionally hazardous, particularly on blind curves at dawn and dusk. Aside from small-scale wood harvesting in the forest, the surveyed areas were mostly quiet and undisturbed by human activities during our visits (December 13, 14, 15: 0645-1730 hrs).

The Mu Cang Chai river valley and paddy fields (MCRV), viewing south from the MCC Homestay hillside bungalows, 15 December 2022 Callyn Yorke

One bird survey was made in the Mu Cang Chai river valley (MCRV), which had been largely converted to farmland. A mosaic of flooded and relatively dry, fallow paddy fields, separated by small berms and homesteads, bordered a rocky riverbed. We walked along the main roadway and berms between the paddy fields in this area, visually covering an area of about 20 ha. The riverbed was only partially visible from our position in the paddy fields and may well have contained additional bird species that we did not observe (December 16, 0700-0900 hrs.).

Guru Maps image showing our survey routes in the Mu Cang Chai area: TBR – the main road survey route (22 km) between the river bridge in central Mu Cang Chai and the summit at 2,100 m elevation (the purple area is government protected forest). Dark circles show locations where we stopped and walked on or near the roadway. Dashed lines (MCRV) represent our approximate survey locations at low elevation (900 m) in the river valley and paddy fields (see text for further details).

Abundance: Numbers following each species entry are the maximum count for a single survey, when multiple surveys of an area were made; Age, sex and molt (when known): ad = adult; imm = immature; m = male; f = female; bsc plmg = basic (non-breeding plumage; alt plmg = alternate (breeding) plumage.

Frequency: C = Common, i.e. found during all or 2/3 of the surveys in appropriate habitats; UC = found only once (1/3 of the surveys) in appropriate habitat. Note: the Mu Cang Chai river valley and paddy fields (MCRV) were surveyed only once and thus the above nonparametric categories do not apply in that case. The MCC Homestay property and adjacent neighborhood was surveyed mainly aurally, then visually on the morning of December 16, 2022.

Observers: Marc Choisy (MC); Glenn Morris (GM); Le Quy Minh (QM); Callyn Yorke (CY). The observer’s initials are used when one or more of them reported a new bird species for the trip list that was not observed by others in our group.

Localities & Distribution: Triple B Road (TBR) in the Mu Cang Chai highlands, covering by car about 22 km from the river bridge in central Mu Cang Chai @ 900 m to 2,100 m in elevation at the summit; Mu Cang Chai river valley and paddy fields (MCRV); In transit observations from the car (mostly by QM, who was driving), between the HaNoi airport and Mu Cang Chai (IT: December 12 & 16); ubiquitous in the appropriate habitat (ubiq).

Ecology and Behavior: aerial insect hawking (ah); taking fruit, berries or parts of flowers (fr); gleaning insects from foliage (ig); probing into surface (pr); estimated height (m) above ground (agl); gregarious (greg); mixed-species flock (msf).

  • Large Hawk Cuckoo Hierococcyx sparverioides 1 (ad) in the late afternoon, this bird flew low over open field and roadway, alighting on a utility wire; it was initially mistaken for an accipiter. We discussed the possible adaptive significance of a hawk-like form, (Batesian mimicry) that is possibly related to its effectiveness as a brood parasite, e.g. of Streaked Spiderhunter (Arachnothera magna) and White-browed Laughingthrush (Garrulax sannio). If host birds are frightened off their nest by the sight of a hawk-like bird, then a female hawk cuckoo may gain a selective advantage when hunting for nests in which to deposit an egg; 1,000 m elev.
