This is the first of the sequence and appears to show a bluetit coming in to land on the roof of Box1.
Finally, we end with an interesting sequence of shots taken by the camera outside Box1.
Suddenly there appears to be a last minute change of plan. This picture was taken the same second as the one above although it is clear that the bluetit has turned through at least 90°.
Wings furled, landing gear readied ...
(Note that this shot's time stamp is only one second later!)
... steady as she goes ...
... and now the mind's made up and he's coming into land.
Touchdown!
I don't know which is cleverer - the bluetit for executing this manoeuvre, or iCatcher's software for capturing it!
