Résumé :	A summary is given of the Hawk Owls Surnia ulula seen in Denmark during the irruption in 1983-1984. Birds were seen from the beginning of September to the end of May, mainly in the eastern part of the country (Fig. 1. 2). As a rough estimate. 350-400 birds are assumed to have reached Denmark. From published and Unpublished sources it appears that the irruption originated in northern Norway and Finland. presumably also in parts of NW Russia. From here the birds moved west and southwest to the coast of Norway. then south to southern Norway and Sweden. Very few birds went farther than Scandinavia and Denmark.
