During the 20th century, there has been a rapid decline of the White Stork throughout Europe due to shrinking habitats and pollution. There is still a considerable population of the White Stork in Hungary, but maintaining this population requires considerable protection activity. I studied the migration and the breeding of the White Stork from 1989-95 in N Hungary. The population levels of this species between 1989-1995 has been greatly affected by man-induced changes in nesting sites, affecting both the quality and the quantity of the nest bases. Storks seem to prefer the traditional nest-bases (chimneys, trees), where higher breeding success could be observed. The traditional nest-bases are occupied by early-arriving older birds. These older type nest-bases were more suitable than the modem equivalents (on electricity poles).
