Birdbox & Nesting

The birdbox that Jon put up outside the window, is now home to some blue-tits.

I can see the parent birds flitting back and forth (and boy, do they!) taking food to the nestlings, as I sit in the living room, on the sofa. Yesterday I went out and took the photos above, and the blue tits hardly broke their stride! I didn't disturb them at all. They just kept on, feeding those nestlings! The cat was pretty interested though, so I might have to keep an eye on that, when the baby birds begin to fledge.
