Thanks SQUIRL033... I appreciate your comments...
It was probably locked onto a leaf in the foreground... I had to shoot through a small opening in the leaves and there was a breeze that may have caused a leaf to steal the focus at the last moment...

looks like your lens may be front-focusing by a couple of inches.. the leaf in the left foreground appears to be sharper than the bird... though in dense cover, your AF may have locked onto the leaf instead of the bird... i assume this is a fairly heavy crop... still, a good job picking the li'l fella out from the leaves!
