Eagles were around overhead. When they drop down too close it’s a mass exit, with much splashing.
At the time I did not know they were Black Ducks, Ellen used the Merlin phone app later to ID them.
Catching the chaotic take off is always hit or miss for me. I can’t be too close, lose focus for a minute, and generally hope the camera does it’s job too.
Above two photographs are the same flock, below was a second group.
