I wasn't kidding about the bird. Calibrated monitor? Oh, please. I see it in my iPhone. It looks like the silhouette of an accipiter, an American kestrel to be specific.
Oooh, could it be? I get a chance to correct Neuro on something not at all related to cameras? ;-)
Kestrels (Falco sparverius) are falcons- the only 3 accipiters in N.A. are the Northern Goshawk, Cooper's Hawk, and Sharp-shinned hawk.
