Cupped Wings-Descending Ducks

These three ducks are in descending flight with their wings cupped.  They are gliding toward a pond for a landing and the center duck has put down his feet to help slow the descent.  Mallard drakes on the left and center, one hen on the right.  There were quite a few ducks on the pond and during the spring they are flying with more frequency on their "courtship flights."  The flight speed is considerable, even when descending like this, so keeping sharp focus is always difficult.  Crossing ducks are easier to keep focused but the shot is not as dramatic.  On this shot the center focusing points were active so I kept them locked on the center bird.  The composition would have benefitted if the three birds were higher in the frame, though.
