Crow Harassing Hawk

Picking up the newspapers on Christmas, I heard crows. The air was cold and I only had on reading glasses, but I could see them diving at the branch of a tall tree.

When I stepped frame by frame while editing in the iPhone’s photos app, I got an experience of the ‘live photo’ that I wanted to share. Nothing is ever so easy, but it did turn out well enough to see the hawk flinch:

  infinite= TRUE,
  speed = 0,
  fade = TRUE,
  cssEase = 'linear')
