 I think it highly unlikely that the rooks are having any effect at all 
on mature trees.  What may be ocurring is that your 18 acres are now
more attractive (to birds) than their former territory was.  Here we
have crows, not rooks and other cedar spp. but choice habitat is pretty
much the same.  Hope this helps,
