This is the day we think could be departure day. I put a timer switch on the camera, and set the video recorder, in case they did a dawn break, but they are still with us at noon. The birds are very restless, with lots of preening activity and occasional bouts of violent wing flapping. It's a beautiful day - quite breezy, but with a clear blue sky and bright sunshine - just right for a maiden flight (apart from the fact that 2 magpies have been seen in the garden on several occasions). One chick actually hopped up to the hole, staying there for a few seconds, before scuttling back, and retreating firmly into the nest cup, apparently overcome by his daring. Another chick picked a small piece of dried moss from the nest, and held it in its beak for a while - a comfort blanket?
