Scaring Effect of Face of Mannequin on the Rufous Turtle Dove Streptopelia orientalis

Abstract: Experiments were conducted in order to demonstrate that 1) the individual variation of responses to visual stimulus by Rufous Turtle Doves Streptopelia orientalis and 2) the differences between responses to stimulus presented to only one dove and two or more. Three doves were used in the experiment in which two mannequins were placed by the two feeding sites, respectively, in a large cage (58×20 m, height 12 m). The mannequins, one was covered the whole body with red cloth and another was the same as the former but exposed her face, were changed the setting places randomly. The responses to the stimulus were measured by foraging behavior of doves, e.g. the amount of food that bird consumed, and the time from feeding to the onset of foraging.1) The control experiment in which no mannequins were installed by the feeding sites shows that birds had no tendency to prefer to one feeding site.2) The responses to the stimulus differed among individuals. Dove A clearly avoided the mannequin that exposed the face, and Dove B avoided two mannequins irrespective of the face exposed or covered and did not come to feeding sites for 11 experimental days. Dove C also avoided the two mannequins for the first 6 days, and thereafter visited the feeding sites without any particular aversion to one type of mannequin.3) The experiment involved Doves B and C showed that the latter appeared to the feeder exclusively, while the former visited there once.4) In the experiment involved all three doves, Dove A became to visit two feeding sites and Dove B also appeared to two feeding sites. Interference by the feeding site was recorded between individuals in which Dove C was always dominant to other doves.5) The result of the experiment involved two or more doves appear to be strongly reflected the behavior of the individuals that responded to the stimulus rather weakly.6) I discussed the changes of the foraging behavior of doves, when they were used in single or plural individuals in experiment, from the view point of acclimation to the stimulus with the progress of experiment, individual interference, and the change of behavior of doves when they formed flocks.
