The most incredible and misunderstood bird in the world.
They make great pets too and you can just grab one off the street, but you gotta be careful how old they are because if they're too young they haven't gotten the crop milk yet and won't survive, and if they're too old they've probably already mated, which they do for life so it and its mate will be depressed and not survive.
Good blog. These birds haven't been neglected by biologists: I refer you to my man Darwin. He bred 'em, and devoted a big chunk of On the Origin of Species to their adaptations. Maybe just as important to his ideas as you know, finches. https://www.darwinspigeons.com/ for maybe more than you want to get into.
