I have a blue tit nesting in my bathroom vent he she has been there for 2 years now I didn't have the heart to turn him she out so I've turned the fan off and I open the window instead let's me take a look when I take the cap off from this side and soon has I enter the bathroom for a bath or toilet I hear little tapping feet and beak it's quite lovely to be honest that I can give a safe home we have a lot of hawks here I was devastated last year I was sat watching the sparrows and down it came right in front of me and snatched one away did the same with one of our robins I know it's nature but I wish it was designed differently I love my birds in the garden so therapeutic I have a old Belfast sink covered with plants around so they can bath I hope we see lots more coming into our gardens 🤗
