When I was growing up in England we had a saying "10 crows are rooks and 2 rooks are crows".  I used to apply the same reasoning to Australian Ravens and Little Ravens.  However during my reign as GBS Coordinator I noticed that there was an a small but definitely increasing number of observations of flocks of 20+ Australian Ravens.  I followed this up with the observers of such flocks in year 23 and they were quite convinced that they had not seen Little Ravens on those occasions.
Much as I hate to disagree with wise young (from my perspective) birders such as McComas on that basis I think it is best not to rely on flock size as distinguishing these two species.  Voice is still a give-away as are the hackles if you're close enough to see them or their absence.  (I'm not sure if you can see an absence.)
