AB Anthropogenic debris, particularly plastic pollution, has emerged as a significant environmental threat tobiodiversity. Given that seabirds interact with artificial debris through ingestion, entanglement, and nestincorporation, it is particularly important to quantify the quantity, origins, and chemical composition of thesedebris items. In this work, it was evaluated for the first time the occurrence of anthropogenic debris in nests ofyellow-legged gull (Larus michahellis atlantis) in biosphere reserves of the Canary Islands (Spain). A total of 48abandoned nests were collected from five remote and hardly accessible sampling areas, revealing that 81.3 %contained anthropogenic waste, with plastic accounting for 34.7 % of the debris, followed by metal (33.6 %) and paper (19.6 %). On average, 32.8 ± 40.9 items were found per nest. Regarding the origin, food packagings (47.8%), personal hygiene products (21.7 %), and textiles (15.8 %) were identified as the predominant sources.Furthermore, the polymer composition of the plastics was characterised by means of Fourier-transform infraredspectroscopy analysis, being polyester the most abundant (38.2 %), followed by polyethylene (25.6 %) and rayon(10.3 %). The incorporation of anthropogenic debris into nest construction may result from outdoor humanactivities carried out far from nesting areas
