A bird has been roosting in a gap in our roof eaves for the last few days. We would like to close the gap and I’m conscious that it is important to do this before nesting season begins. I feel bad closing the gap if it is going to be hard for it to find somewhere else or if it will keep trying to get into its new spot. I have several roosting pockets in the garden but it seems they prefer the hole in the roof! I would be very grateful for your advice please.
