Just for the record. The last time I could shoot a Long eared owl at 1/2500 at -ANY- aperture on ISO 640 was uhm, never. The SS is about right for these owls in flight, but it usually starts at ISO 6400 F4/F5.6 and quickly need to dial up to 8k, 10k which I rather stay away from.

Shorties are a different breed and hunt in much better light. You can see the color of their eyes, the darker they are the later they are active.
