Abstract

THE ACTIVATION OF AN INSTINCT CAUSED BY A "TRANSITIONAL ACTION" by HANS LIND1) (Naturfredningsraadets Reservatudvalg, Denmark. Communication no. 58) (With 3 Figures). (Rec.I-III-1958) During behaviour studies on different birds in the last three years I often noticed that a bird might change from one action to another at a time when one would not expect any change in behaviour. In many cases the bird was not in any thwarted situation or in a conflict for which reason the "new" activity could not be a simple displacement. It was characteristic that there was a gradual transition between the two activities through a transitional ac- tion common to both activities. Furthermore, it was often two definite activi- ties governed by different instincts or subinstincts which - apparently "with- out any reason" - succeeded each other in certain situations, sometimes reversibly. It seemed probable that "something" in the performance of the first action caused activation of the other. Before I discuss the possibilities of such activation and its significance for the understanding of some behaviour patterns, it will be adequate to illustrate the phenomenon by some examples. The observations were made partly at the sanctuary Tipperne in West-Jutland and partly at the
