Grand Canyon National Park (Bird in picture is a California Condor)

If you are trying to photograph a rarely spotted animal, there are a few things you can do to keep it from noticing you so it does not run/fly/swim away.
-If possible, always put your camera in "discreet" or silent mode so the shutter or any beeps from the camera will not scare away the animal.
-Stay completely still.  If you have to change angles, move slowly.
-Do not make any sudden movements
Good luck!
