i want to place a tit box in my garden. the garden is small and at the end I have an arbour that is where the ssun starts from about 9 am can I place the tit box there or will the sun be to hot for any potential users. What is the best place please.

As you say in direct sun is a no-no.My box is facing approx North and on a shady trellis.It is the midday and early afternoon sun that is the hottest and that is when the nest box should be shaded

Hear, hear, Bren unless Lizziewales wants roasted Bluetits. I suspect though that Bluetits are canny enough to avoid a nestbox in a sunny position. They seem to spend weeks inspecting and tailoring them, especially the entry hole and I suspect they will soon discover that the interior is too hot for comfort.
