Female Northern Harrier, full dive position. Notice he she uses her fanned tail to bank and reduce speed. I was very lucky with this photo, it was late evening, suddenly there was a gap between thick clouds and very strong god rays created this dramatic effect.
Tech is Canon 5D MKII + 500 f/4 IS + 1.4X TC f/5.6 1/2500 sec ISO 800. SW: Canon DPP 3.7 Digital Processing: crop and sharpen (the sharpness of 5d mkii files is really amazing).
Hope you like it.
