Anyone shooting wildlife up-close will tell you the shutter sound will cause critters to disappear quicker than a blink. I found the only solution with my D90 is to use a longer lens and crop the photo. Unfortunately, that makes shooting animals on the move a little more tricky, especially the lightening fast hummingbirds. When standing in the middle of these little guys, I've learned to gain their trust and rely on my Nikon S9100, which presents it's own set of problems. I'll save that for another forum. That said, I've managed to get some good hummer shots. I seldom head out the door without at least 4 cameras at my side. The best solution to most camera problems, making sure you have backup cameras along!
