Another entirely man-made problem.
In the neolithic, at the eastern end of the Mediterranean, we domesticated for a food source, the rock dove. It is not a common bird that needs very specific conditions for nesting, that we could easily provide.
After it was “ours” for thousands of years, and bred into freaks, we let the Columba livia f. domestica go feral everywhere that humans took the middle eastern / southern European agricultural revolution, and further in east Asia even.
In terms of quantity and distribution Columba livia domestica is now the most successful type of feral domesticated dinosaur in the history of this universe.
We deserve to be shat on.
