"Orderly March"

If I didn't know better I would have guess you used the cloning tool in Photoshop and added the entire flock of geese!  Of course you didn't so I say a really terrific photo, well done indeed.

Michael,  I am glad you realized that there was no cloning or post-processing here!  I am always intrigued by bird behavior and it took me a several hours of patience to get this shot.

Snow geese in very large numbers arrive near my home town towards end of March.  When they see a bird of prey in the skies above, they all rise up simultaneously and take to the skies to confuse the hawk or eagle above.  When the predator leaves, they circle back and get to the marshland.  Few geese take their time to walk patiently along the rim before jumping into the marsh.  It is generally chaos - but when you see "order" like this, it is time to press the shutter! :-)  Thanks for your comments.
