Birds nesting in roof eaves
We've currently got a sparrow and starling nest under the roof eaves on each side of our house. We've had them for a couple of years now. I'm struggling to find online whether there's any maintenance to the nest area you're supposed to undertake when it's under the eaves? I know that for nestboxes you're advised to disinfect once a year once the birds have moved out. I'm guessing that you're not expected to be able to reach the eaves nest area as it's only accessible through a small gap, but I wanted to make sure there wasn't anything we're supposed to do over Winter etc.
Thanks for any help.
