I suppose there's always the chance that she's just very placid. A few years ago , a dove fell down our chimney. There was a gas fire infront of it. Eventually, we managed to dismantle it all to see what the noise was. The dove was very dirty,but seemed ok. I got a towel to put around my hands incase it pecked me when I picked it up. It was an amazing experience I will never forget. The dove just accepted what I was doing and didnt flinch. I put it on the windowsil, and after a minute or so it flew away to a tree in the garden. Minutes later it flew away.
I can now understand where the saying 'Gentle as a dove' comes from. Here's hoping it is just a very friendly one, as they are wonderful birds.
