The automatictrackingofbees whilepollinating macadamia trees is important for the understanding of reproductive biology and fruit yield. We present techniques for tracking these small targets in an uncontrolled illumination environment and where the background is not fixed. Our results indicate we can tack, based on color, bees moving in 3D in paths over 3s long (72 frames).
