This record contains the data and R scripts associated with the article Assessing temporal and spatial variation in the diet of the Common Kestrel (Falco tinnunculus) using web-sourced photography. It includes the dataset used in the analyses, a full analysis script, and a statistical core script. These materials are intended to support transparency and reproducibility and should be used together with the published article, which provides the full study background, methodological details, and interpretation of the results.Note: Numerical prefixes were added to filenames to keep the files in a clear order. When running the scripts, users may need to adjust either the data filename or the import code accordingly, for example by removing the leading number from the filename or by adding that number to the filename specified in the code.If you have any questions about the data or code, please contactChengtao Wang (wangct@bjfu.edu.cn); Yuanxing Ye (yeyuanxing@bjfu.edu.cn) Declaration of generative AI and AI-assisted technologiesDuring the preparation of the R scripts included in this record, the authors used ChatGPT (OpenAI) to assist with code development, refinement, and organization, as well as to help evaluate analytical options. The authors critically assessed and confirmed the final analytical framework, code, and outputs, edited the materials as needed, and take full responsibility for the content of this record.
