In My Sights

I was actually taking some photos at the library community garden that I do every week, of some sulfur butterflies on the late blooming purple asters and I heard a noise behind me. I believe it is an immature Cooper's hawk (I am not lucky enough for it to be a goshawk and too big for a sharp-shinned... I don't think.) If anyone has a better guess please tell me. It did a dive and swoop on the bush raiding it for sparrows.
It didn't stay on the ground long which is a good thing I had my camera all ready to go, it took off and landed on a nearby roof, I tried to get another photo of but it was having none of it. I do love my hawks though <3 and honestly take it as a messenger spirit since it seemed to sneak up on me so.
