Hi Rob,
It's an unusual story with me and pigeons! It started some years ago with finding a young wood pigeon that had fallen from a nest by a main road, in Oxfordshire. We hand fed him/her with success then a second one! Last year in Penrhyn Bay local pigeons adopted me, then pigeons needing a home turned up, one who wobbles, can fly but likes being indoors! Two others who cannot fly also are with us! And a dove! How they come to us I do not know? But we love them! I've witnessed 3 sparrow hawk attacks and every time we were able to save the pigeons (visitors twice, once one that can't fly) great birds, amazing how bright they are when you get to know them!
