On our last evening at Bosque, the hoped for sunset colors at Ed Kranepool never materialized. It turned out to be one big gray dark dud. But more cranes flew into the pond in the near darkness than I had seen on the whole trip. So I got my flash and started playing.
As Denise likes to say, creating good blurs at extremely slow shutter speeds is like playing the lottery. And that goes double when you are trying for a good flash blur :)
Canon 70-200 f/2.8L IS II with the 1.4X II TC (hand held at 280mm) with the EOS-1D MIV. Manual flash at 1:1. ISO 250" 1/4 sec. at f/4 set manually was about +2 stops. I finally remembered to set rear curtain synch so the ambient blur is behind the flashed exposure where you want it.
I did some fancy stepping in Photoshop to darken the flashed heads of the two cranes.
