Photography Tips and Tricks - 78 (Most Important Setting for Bird Photography)
I take a lot of bird photos and the shutter speed is what I pay the most attention to. If the bird is going to move a lot (flying around), I try to keep my shutter speed at or above 1/1000 of a second. If they are perched and not moving, then I am okay with going down as low as 1/125, but still like to keep it closer to 1/500 or so.
