It consists of a fine-grained image dataset covering 200 bird species. The data is primarily sourced from two channels: first, field data collected via smart monitoring devices deployed in nature reserves (with relevant geographic information removed); and second, supplementary image data legally obtained from public online resources.  The dataset is constructed around 200 bird species. During data processing, intelligent noise cleaning techniques were applied to deduplicate, filter low-quality images, and remove abnormal samples. Additionally, a fine-grained annotation system was designed based on expert knowledge, with annotations including species names. The dataset comprises a total of 10,000 annotated images, making it a fine-grained bird image dataset tailored for ecological scenarios.  This dataset effectively supports model training and evaluation for fine-grained image classification tasks, providing a reliable data benchmark for the application of foundational artificial intelligence models in ecological conservation and scientific research.
