Rubbish dumps provide an extra and constant food source for many birds. The White Stork (Ciconia ciconia) is one of the species that have taken advantage of these new foraging areas both during breeding season and during the winter. This study analyzes data collected in the Spanish province of Cordoba throughout five years between 1992 and 1998 on the biology and breeding success of the White Stork and the influence of rubbish dumps. Breeding success varied significantly between years and areas in two of the study years. A banding program from 1990 to 1998 resulted in 145 storks being marked as nestlings. Of these, 49 were resighted at least once by May 2001 (34% resighting rate) and 16 of these birds were resighted as breeders at a mean age of 2.87 years. 75% of them were breeding close to rubbish dumps. Fifteen birds were resighted during wintering time, of which twelve were at rubbish dumps.
