Summary
In both sexes the age of first-breeding Peregrines varies among individuals, but on average females start at 2,0 years, males at 2,5 years. We describe a successful breeding attempt of a first-year male in the wild. The isolated breeding site is situated at a distance of 65 km to the next occupied territory. The breeding success is presumably due to lack of competition with other adults birds and to sufficient food.
