Stuck!

Not really.
Last week the blue tits were busy going to and fro to the bird box but they are visiting less frequently as I guess they are getting ready to lay their eggs. I hope so.
I was a bit worried yesterday as I saw a starling on the perch looking into the box. However, all seems fine.
I don't use a tripod very often but I did today as I thought I might have to wait some time for a blue tit to appear and I was right. About thirty minutes. A fine excuse for doing nothing for half an hour I think.
P.S. an adult blue tit weighs less than an AAA battery
