I have just bought vaious bird boxes and should like to put them up
around
the garden.

The question is - how do you secure them to the tree trunks because I
thought that banging a nail into the tree will kill or hurt it.

Three- or four-inch nails shouldn't kill a tree; but I suppose there's
some risk of admitting an infection, especially with the plum family.
They would certainly spoil the tree as timber, but that's unlikely to
matter. You can use galvanised steel wire (from the diy shop or
ironmonger) round the trunk and through the holes in the box. This
should be replaced every year so it doesn't get embedded in the bark or
restrict growth. (Black army telephone wire is wonderful stuff for all
sorts of bodging: it used to be common and cheap in surplus shops, but I
don't know about now.)

I'm guessing that if the box is a bit wobbly the birds may not like it,
so you may need to jam a wedge behind it if you can't get the wire
tight.
