Was your focus point on the sky, or were you inadvertently in manual focus mode thinking you were in auto? It sure looks to me like a focus issue, and not motion blur or camera shake.

Ypur shuutter speed was 1/2000 sec so I would say it definitely was the focusing. The D90 has 11 focus points and it does an OK job but its not the fasted AF around. What focusing mode was the camera set for?

Looking at the image more closely, I'm even more puzzled. There are enough tree branches that are both nearer and farther than the bird, that SOMETHING should be crisp. Nothing is.

ive had the lens for awhile now, i was shooting in auto focus, dynamic focus point and ive never had an issue in the past thats why im wondering if its the camera its self. im debating on sending in the camera into nikon to have it looked over cause i still have the warrenty on it..
i tried to even take a pic of a robin tonight but it turned out the same and in both pics i was using a tripod..
The 80-400 might be the problem. I found the AF to be very slow on my earlier cameras, it got faster on my D300 and D3. I noticed that my 80-400 had difficulty maintaining AF on a subject. I was constantly having to reacquire focus on my subjects.

The Sigma 135-400mm f/4.5-5.6 APO Aspherical RF is one of those lenses that seems to have broad sample variations and generally people either really like the lens or they don't like it much at all. If you have the light the lens does seem to respond to small apertures so try f11 if you can, especially at the long end of the range (300-400mm).
If possible, try it on another body. If it performs similarly on a second body then it might be a bad copy of the lens. Also try manual focus using Live View if you have it, to rule out AF mis-calibration.

Stick another lens on it and confirm/eliminate that factor.
