Bird In Tree Clipart Collection. When in gliding flight the upward aerodynamic force is equal to the weight In gliding flight no propulsion is used the energy to counteract the energy loss due to aerodynamic drag is either taken from the potential energy of the bird resulting in a descending flight or is replaced by rising air currents thermals referred to as soaring flight For specialist soaring birds obligate soarers the decision to engage in flight are strongly related to atmospheric conditions that allow individuals to maximise flight efficiency and minimise energetic costs.
Friction and turbulance together cause drag force with counteracts thrust the forward motion of the bird The motion and shape of the bird wing reduce drag considerably Spaces between adjacent flight feathers that smooth airflow over the wing reducing drag Hovering flapping to fly in place requires considerable amount of enery The bird takes a more vertical posture beating wings forward and back and fanning the tail to stop forward motion Non powered flight during which the bird loses altitude
