Résumé :	In 1999 three female Great Bustards were fitted with satellite transmitters within the German-Russian project "Protection of Great Bustards in the Saratov region". One female was located only in the breeding area for 5 months. At this time it used a home-range of some 40 km2. The other bustards left the breeding grounds in the second decade of October or in the second decade of November, respectively. They wintered in the south of Ukraine in the area between the cities Cherson and Melitopol' and the Crimea peninsula. They left the wintering ground in the end of march. Since the beginning of April they were in the breeding area again. The female Great Bustards needed 5 to 8 days for the 1000 km long way (mean speed: 125-200 km/day, maximum 275 km/day). They interrupted the migration for 3 to 4 days. Potential threats for great bustards in the wintering grounds are discussed, especially hunting.
