We've had some swifts nesting firstly in the eaves and now slightly
further into the loft (I presume they've used some of the membrane as
nesting material and made the hole larger), plus some sparrows I think
at another point.

What time of year is a good time to repair / block these holes so as
not to interfere with nesting? And how thorough should I be about
cleaning up behind them?

You should avoid disturbing breeding birds, and generally this means between
June and the end of August. Not doing so, without a proper survey, is
against the law. Even for pigeons!

Pigeons!! about time that law was amended

As to all the others don't mind a few nesting at all, its quite sweet
hearing yet another generation on the go especially the noise when mum
or dad brings home some more grub)

The other consideration is whether you have bats or not - if you've got or
think you might have bats, you can land yourself in hot water if you start
sealing up holes in your loft willy nilly. However, if you get in touch with
Natural England, then you can generally get things sorted for free.


Got a few of them flitting around too, nice to see so much wildlife in
suburbia).
