The lane was alive with birdsong and this little robin's voice was spectacular! I love springtime when the birds really have their best singing voices. Having looked at the film in the nest box, I can see that there are more bits and pieces in there but I'm still not sure who is building as I've seen a sparrow having a look this morning but I don't think he will fit through the hole but I could be wrong. Watch this space for more about the nest box camera.
