Milk thieves

[brian fleming <>]

I go back pre dark Ages and can recall in the blue tits in England doing 
exactly the same thing. I can also recall reading some literature which 
advised that the habit was unknown until the early 1950's and apparantly 
never before the War.

Might it be that the thieving came with the change from cardboard 
closures to aluminium foil? I can't remember when Melbourne changed - 
circa 1960 perhaps.
