Summary
Climate and land use/land cover changes are key factors that significantly impact the distribution of wild species. The black stork, an endangered bird with a high conservation status in China, is particularly vulnerable to these changes due to its long-distance migration. Previous studies have mainly focused on the effect of climate change on the black stork’s breeding season. However, little attention has been given to how its wintering habitats are affected by these factors at different scales. In our study, we evaluated the dynamics of the black stork’s wintering habitat distribution in response to global and regional changes. Our findings indicate that both climate and land use/land cover changes significantly impact the distribution of the wintering black stork. However, the impact of human activities is more pronounced. In order to mitigate the negative effects of human-induced land use/land cover changes on the black stork and other migratory birds, it is crucial to reduce the destruction of wildlife habitats caused by human activities. Additionally, we need to focus on effectively protecting the migratory pathways and wintering sites of these birds, including those that are outside the existing protected areas

Highlights
- Out of 53 black stork nests with nestlings, 14 nests (26%) contained plastic in Central Poland.
- The probability of plastic presence decreased with increasing distance from forest edge.
- Out of 141 black stork nestlings, two were entangled with plastic strings around their legs.
- 26% of nests with plastic indicate pollution of local habitats with plastic and possibly a negative anthropogenic impact on old-growth forest.

Abstract:
The study investigated the presence of waste plastic in fifty-three black stork (Ciconia nigra) nests with nestlings in Central Poland. Although the black stork is typically an old-growth forest species, fourteen nests (26%) contained plastic, predominantly polypropylene string, fragments of polypropylene bags used in agriculture, wrapping foil, fragments of plastic shopping bags, and plastic textiles. The probability of the presence of plastic in nests decreased with the increasing distance of the nest from the forest’s edge. Out of 141 black stork nestlings examined, two nestlings (1.42%) from two different nests were firmly entangled with plastic strings around their legs. The relatively high percentage (26%) of black stork nests with plastic indicates pollution of local habitats with plastic and possibly a negative anthropogenic impact on old-growth forests in Central Poland. In our study area, this impact could be a result of both high forest fragmentation and heavy human activity in forests.
