Food wastes are among the factors with the greatest effects on animal populations. The white stork is among bird species that clearly profit from feeding at landfills, at least in Western Europe and North Africa. However, the rate and the consequences of this feeding are still unknown in the Central-Eastern European population, which differs from the western population not only in terms of migration routes but also in the greater availability of suitable natural breeding habitats due to less intensified agriculture. The aim of the study was to describe the use of landfills and its consequences in terms of probability of nest occupation and breeding effects in different regions of Poland. Although the most important factors influencing nest-site selection and breeding effect are still habitat quality and weather conditions, distance to landfills is important in selection of nest sites. White storks use landfills most intensively late in the breeding season, independently of the density of breeding pairs. The results suggest that the use of landfills is not currently essential in the Central-Eastern European population of the white stork, does not affect breeding effect, and may be more frequent in non-breeders. However, this phenomenon is still developing and requires continuous monitoring.
食物垃圾是对动物种群影响最大的因素之一。白鹳是在垃圾填埋场觅食的鸟类之一，这在西欧和北非尤为明显。然而，在中东欧种群中，这种觅食的速度和后果尚不清楚，因为与西部种群相比，中东欧种群的迁徙路线不同，由于农业集约化程度较低，更适合自然繁殖的栖息地。该研究的目的是描述在波兰不同地区，白鹳对垃圾填埋场的利用及其对筑巢概率和繁殖效果的影响。尽管影响巢址选择和繁殖效果的最重要因素仍然是栖息地质量和天气条件，但与垃圾填埋场的距离对巢址选择也很重要。白鹳在繁殖季节后期最密集地使用垃圾填埋场，而与繁殖对的密度无关。研究结果表明，在中东欧白鹳种群中，目前使用垃圾填埋场并不是必需的，不会影响繁殖效果，而且在非繁殖者中可能更为频繁。然而，这种现象仍在发展，需要持续监测。
