I visited the Great Blue Herons at the Wildlife Center again this morning.  The light was right for the nest on the pole and the wind was perfect to bring the birds in at a good light angle.  I knew that if I waited long enough that one would return with nesting material.  When it happened, I was able to catch this six shot sequence of a landing.  These five images are all time tagged in the same second.

On this one notice that the exchange from the selector to the nest builder is taking place even before the completion of the landing.

Of course, after receiving the stick, the builder spends  a lot of time finding the absolutely perfect position for that stick.  The selector is looking carefully to see what is needed next.
