They're descended from rock doves which were bred for food - in dovecotes.
Why wouldn't be a good idea to eat them?

What's living, mutated & chemical inside the town pigeon is a bit of a
worry. If they were generally acknowledged as safe to eat, the streets
of London would be overrun with 'Kentucky Fried Pigeon' shops.

And I'd be a customer, especially after the Pub :-)
