First attempt at eagle shot. 300mm, 1/500 @f18, ISO 800. What did i do wrong. Thanks in advance.

Camera focused on something other than the bird.
There was nothing else in the frame except the tree.
Nikon D7100 Nikkor 55-300 1:4.5-5.6G ED Lens. DX.
How far, how much of a crop? You can't always get what you can see as sharply as you wish unless you can get closer or have longer lens.
Eagle appears backlit, shutter speed needs to be higher (too much light), aperture needs to be at lowest setting since you only want to capture eagle. You're working at an extreme deficit any time the light (sun) is coming in behind your target. I don't know why the eagle appears out of focus...
Camera may have moved when you snapped the shot.
If hand held try 1/000-1/2000 shutter speed.
May want a larger F stop aperture at the higher shutter speed.
The softness seems to be a mixture of high ISO noise and motion blur. Shooting wide open would have allowed a lower ISO and a faster shutter speed as well. Even if you wanted extreme depth of field, f/18 would be unnecessarily high in most situations, and in this situation you don't need much in the way of DOF.
With good camera-holding skills, 1/500 sec. would be enough, but unless you know how to avoid camera shake and have well developed camera-holding skills, something faster would be a good idea at that level of zoom. The full frame equivalent of a 300mm (DX) focal length is 450mm, so 1/500 is close to the recommended limit (1/FF equiv. focal length) - and that's for somebody with good camera-holding skills. Other than using a tripod or monopod, other tactics include finding something like a tree to lean against or finding something to rest the camera on.

Exactly my point. Camera may have focused at infinity because the focus point was off to one side or the other.
I’ve had similar issues. I changed my metering to spot and continuous auto focus. Just my thoughts.
f18 is too small. Larger aperture would have allowed less iso. Focus not on the eagle. Should have a 2+ compensation to avoid the dark side of the eagle. Tripod would have been a big bonus.
With 300 mm focused at infinity, you don't need any more depth of field than f4. Eagles sitting require 1/1000 and flying, 1/2000 to stop any movement. In your case I suspect it was camera movement.
Thanks for the info. I did not have a chance to use tripod, was shooting out of car window on road. Not much time!
