We still have a full house in box 1, with the two youngsters and the one parent still feeding them. They are a bit more lively now, we haven't seen them sitting in the entrance peering out yet, but it shouldn't be long now before they are away. Here they are yesterday, having a good preening session:
The rest of the time they are just resting in the corner of the box. Although the box is in the shade all day I think they must still be feeling the heat a bit and are not doing much in the way of wing excercises yet.
