All of the action in this 16 part story took place in 4 minutes in very low light at the furthest away from my window part of my front yard. I happened to glance out and saw the mature cooper's hawk on my fence and thought I'd take a few shots. Here it is calmly perched with one foot tucked up for warmth. The time was 4:49pm on a cloudy day.
