One thing I haven't seen for many a year is the top of milk pecked by
blue tits. I don't know whether that is because few people order full
fat milk any more?

Not many people even have their milk delivered any more. I also wonder
if there's been a decline in the blue tit population, as I can't
remember seeing one in recent years while they used to be very common.
