OR....you could forgo all of the varied (and sometimes conflicting) responses when shooting in lighting conditions that aren't changing rapidly (and let's face it...it really doesn't in many cases) and get an incident meter, set your camera on what the meter tells you and then forget about it and shoot away without a worry.
As folks said, your camera's meter tries to make everything this "middle of the road monolithic grey" tone and depending on what's in the field of view, you can get some wildly differing meterings and thus settings.
Think about it this way.
You are outside enjoying the sunshine and you see a great looking gator beside the swamp...so you swing your camera around and zoom in to take a picture. Since your camera is on aperture priority it sets what it thinks the shutter speed should be for "Gator+swamp grass" tonality.
So having taking the picture of the gator you continue to look around and you see your white birds and you think what a great picture it will be, so you zoom to fill the frame with the birds and you snap another shot.
But this one is much differently exposed than the other one due to the presence of the white tones.
You really think that these birds look great so you REALLY zoom in to fill the frame with just one white bird and you take another shot.
And you get yet ANOTHER exposure from the EXACT SAME lighting conditions.
But wait...did the light change between each of these pictures????
Nope. Only the camera's PERCEPTION of what needed to happen has changed.
Now what?
Which of these exposures is the correct one and how do you know?
The answer is...you don't.
What you will do is bring all of these photos into Lightroom and fiddle with them until they are "good enough" as seen on your specific monitor.
If you went the route of getting an incident meter you'd do the following:
When you got out of your car you'd pop the meter to see what exposure the lighting conditions provided. You'd set your camera manually to those settings.
No guessing, no wondering, no chimping or adjusting.
Now, no matter if you are taking pictures of gators, white birds, black birds, green grass, swamp grass, anything at all, your exposure will be spot on! (as long as the conditions don't change significantly, like it suddenly gets overcast or the sun is now behind a giant cloud bank)
As long as your subject is in the same light that you've taken a meter reading in, you don't even have to think about it.
And bonus! No Lightroom guessing either!
Disclaimer: this is my personal take on this, having seen a hundred of these threads and other folks will disagree and say it's not necessary but in my personal experience...it's like going to color TV from black and white. If you've never seen color but only talked about it...you might not get why it's better, but after you've seen color TV, then you can never be satisfied with the black and white.
If you try using an incident meter and realize how much it improves your experience, you won't regret it.
I hope that makes sense.
