Introduction

Together with my wife Katja above Buyant river valley. The snow-capped peaks of the Mongolian Altai in the background are well over 3000 m above sea level. From these mountains it is c50 km to the Chinese border (Xinjiang Uygur Autonomous Region).

In October 2005 my wife Katja and I moved to Khovd in western Mongolia. I work here as adviser to the Altai-Sayan Field Office of WWF Mongolia (www.wwf.mn), and Katja teaches German at Khovd University. In my spare time I try to gather as much data on the avifauna of Khovd as possible. Some results from 2006 are presented here. Background Khovd (48˚00’N 91˚38’E) is a small town (c35,000 inhabitants) at the foot of the Mongolian Altai in western Mongolia. It is situated at c.1400 m a.s.l. in the valley of the Buyant gol (river) which has its source in the Altai. The Buyant is a tributary of the Khovd river which eventually flows into Khar Us Lake (part of the Central Asian Internal Drainage System, i.e. there is no connection to any ocean). The climate (see diagram next page) is strongly continental and arid, characterized by low temperatures and low and erratic rainfall (123 mm/year). Winters are long and cold with an average of five months with mean temperatures below 0°C; springs are dry and windy with frequent dust storms, and summers relatively "wet" and hot. The mean yearly temperature is minus 0.1°C, with monthly means ranging from minus 25.5°C in January to 19.1°C in July. The lowest recorded temperature is minus 48°C and the highest 35°C. Wide daily fluctuation is typical (up to 35°C), and the annual range is up to 90°C. Most of the precipitation falls in the warm season which continues from April until October with nearly 70 % falling between June and August.

Sites & Effort Khovd is situated in a region dominated by desert steppe. The river valley of the fast-flowing Buyant gol near Khovd consists mainly of gravel and heavily overgrazed flat areas (see photo on page 14). Especially along the river a “gazing lawn” developed through many decades of use by domestic livestock. Wetland birds are rather scarce due to lack of suitable habitats2. Gravel-extraction and a brick production resulted in the creation of small standing water bodies next to town. Additionally, some areas near the river are flooded in spring. I visited these habitats occasionally only. Most of my observations came form three sites:

“Airport Plantation”, c.20 ha, no. 1 in Fig. 1, overview Fig. 6. Dense sea buckthorn plantation, poplar coppice, and fallow land.

Stadium and surroundings (“City Plantation”), c. 20 ha, no. 2 in Fig. 1, Fig. 2, 3. Inside the stadium high poplars with plenty of leaf litter beneath. Otherwise mainly open poplar plantation and thorny bushes.

Otzon Chuluu c.26 ha, no. 3 in Fig. 1, Fig. 4, 5. The most productive site. Willow hedges (wind breaks), poplar coppice, elm thickets, dense sea buckthorn, grassland, small vegetable patches, potato field, and fallow land.

Thus the majority of my observations in 2006 came from an area of less than one square kilometre!

I went birdwatching in Khovd on 143 days in 2006, with the main effort during peak migration seasons (March-May, September and October).

Observation days (n=143) per monthly decades, Khovd 2006.

Observations I recorded 186 species in Khovd in 2006. Further four species were seen by others: Common Crane, Eurasian Curlew and Goldcrest by Valdemar Holmgren, and Laughing Dove by Anna Lenhard. All species were recorded through sight observations, except for Red-mantled Rosefinch, which was not discovered in the field, but mist-netted. Thus the total number of species

2 The Buyant gol is obviously not a migration corridor for waterbirds. However, tens of thousands of waterbirds can be seen in Khar Us Nuur National Park, with its several thousand square kilometers of wetlands, just 30 km (as the crow flies) east from Khovd.

recorded in 2006 from a stretch of c.10 km along the Buyant gol valley near Khovd is 190!

Over half (119) of the species recorded were encounter less than 10 times (including 57 species with just one or two observations).

Spring migration of Evermann’s Redstart in Khovd, 2006.

Despite the relatively low overall individual numbers, the different peaks for males and females are clearly visible.

Booted Eagles

Large numbers of Black-eared Kites roost in Khovd, mainly in the “City Plantation” (see photo on title page). Dark morph Booted Eagles (almost 90% of all individuals observed were dark morphs) can look superficially similar and can easily be overlooked among them, especially since they are resting mostly in deeper cover (see photo left) than the kites. This is probably to avoid the frequent attacks by crows (photo right) – which seem to ignore the kites, but get frantic when discovering a Booted Eagle! A list of all 190 species recorded, including the total number of observations per species, the single day maxima (individuals) for each species, and the total individuals per species is given in Appendix 1. Appendix 2 lists the 25 commonest species for 2006.

Special Records & Surprises The greatest surprise for me was the large number of species which can be seen here in Khovd (e.g. 20 species of birds of prey and 12 species of bunting in 2006). If I had spend some more time at the little standing wetlands (gravel ponds, “brick” ponds), the number of species for one year would certainly have topped 200!

During an early morning walk on 22 September with Martin Gilbert and colleagues from the Wildlife Conservation Society (who were passing through Khovd), Martin found Mongolia’s second European Pied Flycatcher (the first was seen and photographed not far from Khovd in May).

On 18 October, Valdemar Holmgren, a birdwatcher from Sweden working in Khovd called me to tell me that he just found an European Greenfinch at the “Airport Plantation”. I jumped into a taxi (there’s a taxi stand right in front of my house!) and Khovd saw its first twitch ever… When I joined Valdemar a few minutes later, we were able to relocate the greenfinch, and even found a second. This observation came almost exactly one year after I found Mongolia’s first European Greenfinch, less than two kilometres away (on 23 October 2005)!

My second try to twitch a rarity in Khovd wasn’t successful. On 29 November, Anna Lenhard, a Swiss teaching German at Khovd University discovered a Laughing Dove in her backyard in the Kazakh quarter of Khovd and took a few digital photographs of it. Over the next days I checked several times the backyard – but dipped.

Other rare species recorded in Khovd in 2006 were Wood Warbler and Corncrake. But also commoner species made interesting appearances, for example Bearded Tits resting in low coppice, far away from water; a Red-throated Pipit which sat on morning the fence of the WWF office in centre of town; the large numbers of Ortolan Buntings, which were resting preferably on gravel plains almost devoid of vegetation; the rather large numbers of Booted Eagles (see photo on page 8), or the very large flock of mainly juvenile Rose-coloured Starling resting in poplars behind the stadium in mid-July.

Flycatcher, Khovd, June 2006.

Acknowledgements Valdemar Holmgren contributed some sightings, called me when he found Mongolia’s second European Greenfinch and was a good companion on several bird walks in Khovd.

Anna Lenhard contributed the photograph of Otzen Chuluu and documented the Laughing Dove in her backyard.

Tom Noah was my connection to the “outside world”, sending me copies of papers, discussing observations by e-mail and on the phone, and exchanging bird news (among others) from back home with me. And he visited us.

My wife Katja joined me on many walks, found quite a few birds for me, and was always supportive in any possible way.

The owners/keepers of the plantations in Khovd granted me access to their property.

Thank you very much!
