Chukh Bird Research Station in northeast Mongolia
If you interested in about this project, please contact us!
Mongolia is located on the inland route for migratory shorebirds between non-breeding grounds in Australia, southern Asia and breeding areas in Asian tundra. However, knowledge of the shorebird populations that use this route is still deficient. The Chukh Bird Research Station /CBRS/ is located on the northern shore of Chukh lake in northeastern Mongolia. It is approximately 20km east of Dashbalbar soum of Dornod province along the Ulz river which is 750km from the capital city of Mongolia. CBRS is coordinated by the Mongolian Bird Conservation Center of Mongolia (MBCC) and the main aim of the CBRS is to carry out long-term and sustainable monitoring of breeding and migratory shorebirds population of Chukh lake, and to conduct ecological and biological studies of the lake and its biodiversity, to define model management. This lake is the most suitable for monitoring, because of the studies on similar lakes in the Mongol Daguur region which have shown that Chukh lake has kept its water level consistent.
Our monitoring activities include biometric measurements, ringing and tracking activities. There are 58 species of shorebirds have been recorded in Mongolia. Of them 36 species have been observed and 32 species trapped in Chukh lake. The leg flag at the protocol for Mongolia is blue over green and we used metal ring on the left leg as well. During the monitoring, a joint team trapped and ringed total 409 individuals from 32 species of shorebirds. We also tracked 10 percent of the total trapped birds including Black-tailed Godwits, Asian Dowitcher, Eurasian Curlews and Black-winged Stilts.
In 2019, we observed, in total, 32,610 individuals of 151 species during our field work. In addition, we have recorded 9 new species of birds in the region. The most commonly recorded species were the Common Pochard, Eurasian Coot, Ruddy Shelduck, Common Goldeneye, Whooper Swan, Swan Goose, Common Shelduck, White-winged Tern, Sand Martin, Black-tailed Godwit and Northern Lapwing in both seasons.
We would like to investigate diet composition and foraging ecology of shorebirds, so we divided the lake into 4 main biotopes for collected a total of 3201 invertebrate samples and identified 14 families of 10 order of invertebrates from Chukh lake. The largest number of invertebrates occurred in muddy biotopes.
Although, Chukh lake is a small-sized lake, it is not only important for migratory birds, but also for breeding White-naped Crane and Common Crane who use it for their nesting site.
Training students was one of our target activities and 6 young ornithologists and students were involved the training activities during the monitoring. We organized also shore bird event for local people and kids near the lake during the period. Hope that we will have another effective and busy season next year.
If you find the bird with blue over green flags (right leg), please let us know and also If you have any questions relating to our activities feel free contact us in following email address: firstname.lastname@example.org; email@example.com;
