Blue Tit House

I know it’s not a great photo, but this is evidence that someone is using one of the bird boxes that ‘im outdoors made. In the depths of winter while everything was covered in a foot of snow, ‘im outdoors kept him self busy in the garage and made two bird boxes.
We’ve put them at either end of the garden, one designed for blue tits and one for great tits. (the holes are different sizes)
We’ve seen birds looking at both and this box is getting a lot of attention. Hopefully they will decide its up to scratch.
