Male American Kestrel. The males are smaller and more skittish than females and difficult to approach. A very long fossil length or some kind of blind of often necessary to get detailed photos of this bird. Here I used my 600II plus the 2X Extender to get a close shot of the kestrel. It was also a pleasure to meet Juan Carlos Vindas (by chance) in the field!
shot with 1DXII 600II + 2X III f/8 ISO 1600 1/3200sec hand held. processed with DPP 4.7. hope you like it.
