what camera do you have?

...both zooms seem not to be good ones because of the quality of the 100%

Sorry to say, but I disagree with NullVier quality of both seem to such just for same reason - picture at 100% picture is very blurry (might have to do with shake that impacts much more at high zooms. The golden rule of Zooms says that you exposure time should be 1/(zoom in mm) second and that is when you're talking about full frame. since most dSLRs have APS sized sensor you have to take into account this crop factor - 1,5 or 1,6 (canon) or 2 FourThirds systems. So to ensure shake blur free shot with say 200mm zoom in Nikon D200 you would need 1/300s exposure time and on Canon D30 1/320s. That is, naturally if your lens or camera itself doesn't have any image stabilization mechanism. And all of it is a subject to how steady your hands are...

I'd be intrested to know if this was off of a tripod, and if the mirror was locked up proir to the shot being taken (can you do that on a D80?)

I'm guessing hand held, considering the EXIF (f6.3 and 1/800)

I don't think you can lock-up mirror on D80, you would have to go for D200 for that. Vibrations introduced by mirror movement are significant only at longer exposures... But anyway one must be realistic about possible quality for 10x Zooms.
