Not quite cadburys mini eggs ??

Curiosity got the better of me in the garden today, the tree nearest to our house in the back garden has been the centre of attraction to a couple of woodpigeon and now I know why !! I did see a nest a few days ago in there but thought it was an old one from last spring or so, but now its apparently in use to two fat looking pigeons, had to wait for the female to leave the nest to take this, hopefully they hatch soon and fly the nest quickly, I'm told there's quite a lot of noise from the young ones ??
