1. It appears that the premium put in 1954 on the shooting of Woodpigeons did not influence the population density of this bird. The average age as well as the survival chance in the following years appeared to be the same as in the preceding years. 2. The number of birds shot in the successive years was used for estimating the fluctuations in the population density in the years from 1954 to 1962. 3. It appeared that the population density shows neither a permanent increase nor a permanent decrease. 4. The migration of the Woodpigeon in Europe was studied. It appeared that there is in the Netherlands an immigration, though on a small scale, from abroad, but the possibility that some of these immigrants would settle here, seems to be but small. 5. Among the factors by which the population density of the Woodpigeon is controlled, the amount of food and the weather conditions during the winter are probably the most important ones.
