Webbirds flying between 6 and 18 m s−1 occupy an intermediate range of Reynolds numbers (which indicates whether fluid flow over a surface is steady or turbulent) between 15000 and 500000 [8]. For flat plates, this range indicates laminar conditions [15], while the flow regime of bird wings seems to WebA bird’s wing bends at three joints, similar to the human shoulder, elbow, and wrist.
