A low pass while he dropped down to join the others.
The flight pattern for the day was a series of wide circles, each one getting lower until they slipped in with the flock.
While that should have made it easier for us there were too many individual flocks. I never knew which one to be closest too. The Storks picked a flock depending on how the circling was going.

This bird turned and thankfully chose the nearest flock. I forget how big their wingspan is, but it’s one of the largest in North America.

59″ – 69″, according to All About Birds. Wider than I am tall.
I have a vivid memory the first time I went out to the big marshes alone. The middle of nowhere, early morning, no people for miles, and I heard/felt the ‘air moving’. A flock of Wood Storks dropped down almost on me, wings flapping and pushing the air. Surreal.
