BEHAVIOR OF JAPANESE-QUAIL IN MICROGRAVITY ON THE MIR ORBITAL STATION

Behaviour of newly hatched and adult Japanese quail was analyzed using videorecordings from two experiments conducted aboard the MIR orbital station. Weightlessness caused problems in motor behaviour of unrestr icted quail. Especially in newly hatched quail (their entire embryogen esis proceeded under microgravity conditions) bodily rotations and bou ncing against the walls of the rearing device ''Nest'' did not allow t hem to feed. The problems with movement and spontaneous feeding were n ot so serious in adult, unrestricted birds. Although some signs of ada ptation to microgravity could be seen, further data are necessary for estimating possibilities of behavioural adaptation to microgravity.
