About 25% of the world's white stork population nests within Poland, making the country the stork capital of the world. After the breeding season, most of the birds migrate to Africa, but nests are typically used year after year. The males arrive earlier in the season and choose one. Larger nests are associated with greater numbers of young successfully fledged, and appear to be sought after. But they often need a lot of maintenance, so after the males return from their winter migration, you can find them busy cleaning and doing a fair bit of reconstruction before the female arrives.
