  • SummaryIn an experimental wind tunnel air speed (vF) and ground speed (vG) of a Myotis lucifugus were measured as a function of wind speed (vW). The bat had a vF of about 4,5 m/sec in still air. With head winds it increased vF and lowered vG to reach stationary flight (vG=0) at a vW of 7,7 m/sec. The rate of wing motion remained at about 10–11/sec at head winds from 0–7,7 m/sec. With tail winds the bat changed to a semi-hovering flight with wing beat frequencies rising to about 16/sec and vF… CONTINUE READING
