The invention discloses a bird identification method and system based on multi-millimeter-wave radar fusion, and relates to the technical field of transmission line bird identification, and the method comprises the steps: obtaining a plurality of echo signals in a detection region; preprocessing the echo signal to obtain a corresponding radar point cloud image; fusing the radar point cloud images to obtain a radar three-dimensional point cloud image of the detection area; performing clustering processing on the radar three-dimensional point cloud image to obtain a point cloud sub-image containing an independent recognition target; bird classification identification is carried out by using the point cloud sub-images; according to the method, the accuracy of bird classification and recognition is improved by utilizing the spatial combination of the millimeter-wave radars, and the millimeter-wave radars utilized by the method have low requirements on brightness and visibility and can be used in all weathers; mea
