The second one with the Asian Collared dove is neat, but that dove would not last a nano second with our cat Emmy, she kills at least one dove a week on average. (she brought in another snake last night) We did not have any collared doves few years ago, now they are here by the thousands and thick as fleas. (year round no limit hunting season) They lay eggs, nest, and raise one hatch after another year round. so small wonder they multiply so.
I think you need a border fence for those doves
