Key Findings
- The study in Barcelona found that yellow-legged gulls prefer nesting on flat roofs or elevated structures, especially in corners with gravel substrates
- Nests were typically located away from ports and on buildings shorter than 12 meters, indicating that building height and proximity to human activity are important factors
- Over 80% of nests contained litter, with its abundance linked to population density, highlighting the role of urban waste in supporting gull populations
