Restoration of sea eagle population: A review

摘要

The population density of the white-tailed sea eagle Haliaeetus albicilla is very low in many countries.In last twenty years,the sea eagle population in South Bohemia was restored by strict protection subsidized by reintroduction.The active help consisted of feeding during winter and building of artificial nests.A new sea eagle breeding population arose in the T r ˇeboň basin area in the early 1980's.Until this time sea eagles had used former breeding places only for wintering,probably coming from the Baltic.The South Bohemian sea eagle population is very unique:it exists in a densely man-occupied landscape,mainly in areas with very intensive carp breeding in artificial fishponds and was partly artficially(help to wintering birds and reintroduction of some individuals)restored.The experience from South Bohemia may have importance for populations of the sea eagle in other areas of its occurence,primarily in the continental conditions.
