Brown-eared bulbul using bounding and intermittently beating

�@After a bulbul has been throwed up forward by quick beating, it does parabolic flight with such a style as jumper in the jump match of the skies. Then, a little lift may be acquired without an increase of the drag. It is the root of the jumper in the jump match of the skies. It is also like the flying style of the paper plane. (Prod.
