Rock doves, which is why pigeon nests look so ridiculous. In nature they nest on rocky ledges and only need a few sticks to stop eggs from rolling over the edge. But if you look at the kind of nests they make in cities, it's funny and then kind of sad.

"Rock doves have been domesticated for several thousand years, giving rise to the domestic pigeon. They may have been domesticated as long as 5,000 years ago."

That's a long history! I had no idea. I thought pigeons were their own species, and people happened to keep them as pets sometimes, kind of like parakeets.

After thousands of years living among humans, I'm not surprised at all that they adapted to our living environments, like cats and dogs. I bet the ones that survive in the city are way more adaptable in their behavior than wild rock doves. There's pretty strong selection pressure in that direction for any animal that lives around human-generated complexity and chaos. Every time there's been a mass extinction event in the past, new capabilities emerged when life finally recovered. I bet this coming age will be full of very clever and adaptable creatures, and pigeons will still be around.
