Résumé :	Except for a number of largely unsuccessful breeding attempts during the second half of the 20th century, the White-tailed Eagle Haliaeetusalbicilla had been absent as a breeding bird in Denmark for more than 80 years, when a population established itself during the second half of the 1990s. Released from persecution and contaminants the population has grown to 37 pairs in just 16 years. Reproductive success has grown with age and experience of the birds, so that the average number of fledged young per breeding pair peaked with almost two per pair 8-10 years after the establishment of each breeding pair. Similarly, the Golden Eagle Aquila chrysaetos reestablished a small population in Denmark from 1999 onwards after probably having bred here until about 150 years ago. For both species, this success was facilitated by conservation efforts including protection zones around eagle nests, monitoring and public outreach mainly carried out by volunteers from the Danish Ornithological Society / BirdLife Denmark.
