Despite the vital importance of wetlands globally, these habitats have increasingly received anthropogenic materials, such as plastics, which can impact wildlife support. commonly found in nests Eurasian spoonbill (Platalea leucorodia), presence materials has never been quantified. Here, we monitored occurrence nesting (ANM) Camargue wetland Southern France during two breeding seasons (2021-2022). We also investigated their potential function by associating with breeder experience (based on age) and hatching success. Out 439 nests, 39 % contained at least one material item, usually plastic sheet-like shape white-transparent colours. Throughout season, proportion ANM nest lining increased, coinciding a decrease natural (i.e. vegetation). A higher green was detected egg phase compared to other phases development. Our results did not support correlation between experience, nor Further studies (e.g., physiological through necropsy or fine temperature assessment) may disentangle benefits adverse effects waterbird
