Blue Tit Behaviour

I saw this Blue Tit on the front garden feeder on Sunday clearly holding a sunflower seed between both its feet to keep it steady for pecking. I don't know why this surprised me but it did. I wonder if they always do it like this.
I like to keep an eye open for regional and archaic bird names. There is a wonderful book called British Nesting Birds by W. Percival Westall, Dent & Sons, 1922 which gives a variety of 'local names' for each bird. Some names commonly in use then are now archaic themselves. Robin, for instance, is listed as a 'local name' for Redbreast.
Anyway my point is that in our household the favourite name for the Blue Tit is 'Billy Biter'.
