| Abstract | Based on resightings of neck-banded Greylag Geese, we calculated mean annual survival rates of76% forjuveniles, 74% for subadults and 83% for adults. The survival rate was significantly lower over the winters 1989/90 and 1990/91 than over the winters 1985/86 1988/89 and 1991/92 for adults (80 vs 87%). In the winters 1989/90 and 1990/91 , hunting on Greylag Geese was intensive in southwestern Spain. Greylags wintering in the Netherlands (mainly the Dutch Delta) had significantly higher survival rates than birds wintering in southwestern Spain in both juveniles (90 vs 72%) and adults (94 vs 85%). Most losses occurred dLlfing autumn migration and just after alTival into the winter quarters. LeifNilsson & Hakon Persson, Dept. of Animal Ecology, Ecology Building, S-223 62 Lund, Sweden.
