I believe one of these birds ended up at my fathers garden in North Lincolnshire. The bird spent the best part of a week in his garden, showing no signs of injury, nor any sign of wanting to fly off straight back off.
After a week of food and water, the pigeon finally took off again. Hopefully it got to whereever it needed to.
