Interesting stuff - thanks chaps.
I have a lot of cats doing the rounds, hence my decision to site my box about 3m up the tree. That tree is really my only option for any kind of height. If I placed the box on the side of our very short/modest shed I think the cats would be a huge threat.
There are grey squirrels, too - they zoom about through the branches of our tree and neighbouring trees.
And parakeets (ring-necked pests)
Plus a whole posse of magpies that appear on a regular basis.
It’s pretty busy!
The only species I know have nested in my garden previously are blackbirds, robins & dunnocks. As I said earlier,the blackbirds are back this year in next door’s cypress.
So the BT idea was always going to be a gamble I guess.
I don’t know the exact dimensions of my box from hole to floor but it’s a fair old way...much deeper than the old box I had.
The hole is 32mm which so I’ve read is on the large size for BTs... no metal plate either.
I saw a PHD paper online recently by someone at Imperial College listing stats for 50 or so boxes in oak woodland- pretty sure woodcrete featured there as the favoured material.
