The dataset was compiled from video recordings of hive landing boards at a local apiary in the Vilnius district during the 2023 beekeeping season. A stationary camera, positioned approximately 30 cm above the landing boards, recorded footage at 1920×1080 resolution and 30 frames per second. To ensure environmental diversity, recordings were taken under both sunny and cloudy conditions. Individual frames were extracted from the videos for annotation. The dataset consists of high-resolution images from four beehives, each housing a colony exhibiting fanning behavior, and captures a variety of environmental settings and insect activity. In total, 18,000 frames were extracted—equivalent to approximately 10 minutes of continuous video—with 15,111 frames containing visible fanning bees. Across these frames, 57,597 individual instances of fanning behavior were annotated. 84% of the images contain fanning behavior, while 16% do not.
