Changes of the Hungarian White-tailed Eagle population in the relation to protection efforts Horváth Zoltán and Gáborik Ákos
Historical background Negative effects Frim the XIXth century contiuous habitat losses, vanishing of wetlands (feeding and breeding areas lost) disturbance of the intesive forestry and agriculture technologies expanding use of chemicals (e.g. DDT) shooting by hunters, fishermen poisoned decoys egg and chick collecting Between 1970-1980 10-12 known breeding pairs, estimated 20-25 pairs. Positive effects Protected since 1939 (allowed to be shot only at fishponds). Strictly protected since 1954 BirdLife Hungary founded in 1974, as an effect of their monitoring activity, the use of poisoned eggs finished in 1981 In 1987 MME (BirdLife Hungary) and Somogy Nature Conservation Organization Started the Whitetailed Eagle Protection Programme In 1990 an official nest protection zone of 100m radius was introduced, the National Park Directorates got strong and the Nationwide Ranger Sercice built up.
WTE in Hungary before the Program (1986)
Activities in the program First steps Building the coutnry-wide observer network. Organize nest control and collection of breeding data Starting legal protection initiation procedures for wetland habitats used by White-tailed Eagles. (In Southern-Transdanubia, mainly in Somogy county) WTE-conferences to exchange experiences Collect funds from tenders and sponsors Landpurchases Pracrical activities and achievements of present Nationwide observer network (80 persons, in 18 regions nesting, breeding data, protection zones) Colour ringing Winter feeding and synchronous census Artifical nests Measuring dangers Hungarian pouplation 236 pairs
Colour ringing Joining the European program in 2004, number of breeding pairs >100 altogether 398 chicks ringed In 2011, 69 chick got colour ring
Winter feeding and synchronous census Winter feeding Significance in protection is decreasing, helps read colour rings Synchronous census In every January since 2004 In 2011-ben 461-494 specimens observed. The wintering population (resindent and northern altogehter) min. 800 specimens.

First one in 1976 Artifical nest installations Altogether 80 ones (mainly in the early period of the program) Importance is decreasing contiuously, only if reasonable
Dangers and risks Electric shocks Mainly on medium voltage lines Poisoning Mainly carbofuran, phorat, lead and mercury
