Mongolia is approximately the size of Western Europe. Yet due to a lack of funding, poor infrastructure hindering travel, and the small number of professional ornithologists, only a few short-term automobile surveys had investigated populations of the Great Bustard in Mongolia before our research began.

Though scientific capacity in Kazakhstan is better-developed, reports of Great Bustard observations have been few in number. This is probably due to the extreme rarity of this species in Kazakhstan, its wariness, and its preference for human-modified habitats which are less frequently targeted by biologists.

In order to detect remnant populations of this bird, our regional teams interview local people as to its historic and current distribution. In the field, we work with local experts, including biologists, members of the hunting community, or observant herders. Travel through the remote areas in which these remnant populations are found is painstakingly slow. The team carries out frequent observations through spotting scope (telescope), since Great Bustards in this region typically move away from humans before they can be spotted by the naked eye. When combing territories for previously unreported populations of Great Bustards, it is typical for us to locate new birds only once every two weeks.

Our team requests protection for areas of critical habitat, such as breeding sites and migration stopovers. We incorporate data concerning bustard locations into studies of bustard habitat use patterns and population genetics.

Bustards in Winter

Master's student U. Tovshin is embarking on an adventure to determine how many Great Bustards tough out the Mongolian winter - where average low temperatures are -30C (-22F), sometimes reaching -50C (-58F). Wishing him safe travels! February 2012

 

Two empty leks

Leks are traditional areas Great Bustards visit each spring to display, mate, and nest. This summer we were unable to locate lekking bustards at 2 of our 6 study locations. We are unsure whether bustards did not arrive to those sites this spring due to inclement weather, or whether those small populations have permanently disappeared. We have found high rates of mortality due to poaching among our tagged bustards. July 2011

 

Wet summer dampens nesting efforts

This summer was extremely wet in northern Mongolia - indeed, our team was unable to travel in mid-June as bridges collapsed and roads were wiped out by floodwaters. We believe that flooded fields may be one of the reasons we were able to locate only four nesting females this summer. June 2011

 

Bustard lek confirmed

On the road to our field site this summer, we were able to confirm the existence of a bustard lek (breeding site) we had long suspected to exist. We were elated to observe displaying males and three nesting females. However, two weeks later we were dismayed to hear that pesticides had been sprayed in the fields preferred by the bustards. Pesticides decrease the protein-rich insect food base essential to rapid growth of chicks, and trucks spraying pesticides sometimes crush eggs and flush mothers, making eggs and young vulerable to predators.

Fall Surveys Indicate Poor Nesting Success

Great Bustard chicks remain with their mothers for approximately a year. In the fall, they move with their mothers to spots where Great Bustards gather for migration. This autumn, as in previous autumns, our surveys revealed single adult females, but few females accompanied by large chicks. Reproductive rates for these Central Asian Great Bustard populations appear to be low. October 2010

 

New Mongolian Bustard Population Centers Identified

This fall the research team toured new areas of Northern Mongolia in search of new Great Bustard population centers. We identified previously uncatalogued Great Bustard migration gathering points. Detailed interviews with local residents lead us to believe that two of these are also "leks," or traditional bustard breeding display arenas. If this is confirmed in the spring, these sites will be listed with the Mongolian government for greater protection. September 2008
