Clearly there is a difference between the blue tit first learning to
peck, and then learning where that behaviour might again be useful. But
this doesn't make it obvious to me that one sort of learning is
disqualified from being memetic (actually I don't think either example
is memetic, but that's not the point). Why should information about
where to apply a skill be any different from information about how to
acquire that skill, or information about anything else for that matter?
It's all information.
Blackmore says the milk-bottle-pecking isn't memetic because the birds
that do it already knew how to peck, so they haven't really imitated
anything. I'd suggest that this is because in her head "imitation" is
synonymous with "replication" - so whenever something doesn't count as
imitation it is automatically *defined* as not being memetic.

As a matter of interest, I have had milk bottles delivered to my
doorstep all my life, and never to my knowledge had any vandalized by
birds of any description. I have moved around the UK *a lot*. But my
mother-in-law (in the North East of England) always leaves an empty can
out for the milk-lady to pop over the top of her milk bottles, since
otherwise she is plagued by marauding blue tits. Bizarre.
