Day 217.  This almost looks like a time lapse photo showing the wing movement of migrating geese.  But, it isn't a single goose, it is part of a flock that flew over.  When they fly over they sound like a room full of noisy people.  It is cool to see the position of the wings during flight.  It's not all soaring.  There is a lot of work involved for them to stay in the air, and they have to stay in the air to reach their destination.  To get where you want to be you have to keep moving.
