Big bird in the river

.

This would have been my second choice for "black and white in color" Theme Day.
It was a cold December day in Switzerland.
I was hurrying back to Grandchamp after getting a video of the big fish jumping UP the waterfall (then they swim against the current, up the river to their yearly spawning ground).
I was alone, it was getting dark, the narrow path along the rushing river was slippery, and I was imagining how I could easily fall to my death in the freezing stream with no one to save me.
Suddenly a white being rose up right in front of me with wings spread to a meter and a half!!
An angel??
Regaining my wits, I backtracked to try to find where it had flown to.
There is was--a beautiful tall Grey Heron standing in the water.
It paused just long enough for me to get a quick snapshot.
It was a welcome sign that I was not alone.
