I have a nicely-shaped conifer which is now about six feet tall but it is hollow down the middle. How can I get the centre to fill out so that, in the future maybe, the birds can use it as a nesting place?

No, the centre is not brown and dead, there's just no visible growth.

I don't think there's anything you can do to get the tree to grow in the centre...The new growth comes from the outer branches and twigs. I suppose it's partly the lack of light inside as well as the growth habit of conifers.

Thank you very much for your replies to my question. I have another conifer of the same type, age and size and this is quite dense in the middle so I can't understand why the other one is like it is. There is plenty of growth on the outsides but very little in the centre.

That 'is' strange. I'm just sorry I can't suggest any remedy.

If the centre is brown and dead - then no, there's nothing you can do, I'm afraid. That's what happens to conifers sometimes.
