Blue Tit

Blue tit (Cyanistes caeruleus or Parus caeruleus) is one of my favorites of small birds, busy and lively. There are plenty of them this autumn.

I checked the name in English from wiki and there was an interesting story.

In UK at 1960s of Blue Tits were teaching one another how to open traditional British Milk bottles with foil tops, to get at the cream underneath.

This behaviour has declined recently because of the trend toward buying low-fat (skimmed) milk, and the replacement of doorstep delivery by supermarket purchases of milk.
