Gary - I don't think anyone is trying to attack you or your photography, they are simply giving their opinions on the image you have presented (something that by posting it in this section is what you have requested - if you don't want any crits at all simply use the "just for fun" section - its what its there for

))
That out of the way the image is noisy - and no that is not with any pixel peeping at all (impossible since we don't have a fullsized version of the image to peep on

) but simply looking at the shot you have presented here. That you say you can't see the noise on your computer says one of two possible things to me;
1) you might have a very dark moniter and the noise is just not showing up on your screen. If your on a CRT (big) screen then this could be a factor - though if your using an LCD (flatscreen) I would be very surprised since they tend to run overbright most times
2) Your not quite sure what noise they are refering to.
As for my own views I first thought this show was from a film camera since the noise (little dots in the background areas) has that more grainy look to it. You could try countering the noise if you desire by using some editing software - nothing fancy even photoshop elements or GIMP with some noise removal and layermask effect (so as not to soften the sharp main subject). If you want more info on this then ask.
Also the noise is not all we see of course - there is also the subject itself - well presented and sharp - also dominating a large portion of the shot which is not an easy thing when dealing with such a small bird (which are often very flighty).
