Hello Ev,
I agree with you and Leonardo, its a Stock Dove.
Yes, its often a strange sight with a strange/uncomfortable feeling to see a "wild bird that you dont see often in gardens" in a garden (and then often/sometimes tame), but once you are aware of this, its easier to trust your experience.
Your bird seems a good example for this. Tfs!
Edit: this is dependent on the regular species in your garden. Imagine, you have Stock Doves as regular visitors in your garden?
Therefore I assume, that they are rare there. Right?
