We have a birdbox web cam that has a couple of Great Tits making a nest in it atm, it's very exciting and I can't stop watching them at work.
The kids are really into it and I'm a bit worried what will happen if we don't have a successful hatching :(
We also have robins nesting in our sunroom! I'm not sure that's going to be as successful but if we shut the door they use the broken cat flap and come in that way!
