You are constantly trying to use the lowest possible shutter speed. With something like a perched bird, I'll go down to 1/25. For flying birds, you don't have to get every frame sharp (especially if you have a fast camera like an a1 at 30 fps), so while I used to shoot at 1/3200 I'll now shoot at 1/1600 for cleaner images.

Of course, faster lenses help, and most pros are using a 600mm f4.

But yeah, this remains the biggest technical challenge in wildlife photography.

The more data you generate, the more failures you will have. I've generated about 100 TB in 20 years (photos and video). I have a card failure every year or two with professional grade cards. I insist on two card slots.
