In the great tit nest box

There are 4 chicks, and one egg that has not hatched - a bit of it is visible in the top right frame. 

There are shots from 2 cameras in this composite. The camera that took the shots on the left unfortunately only works for about a minute, then the picture freezes, and it has to be powered off.  The other camera works all the time, but only gives 2/3 of the frame, and is not really in focus. It's still a privilege to get even these imperfect views of the growing babies.
