Yeah! They tend to specialize against particular species! I don't have research documents on hand atm, but I do have a terrifying video about them from zefrank

  Sorry I didn't reply earlier when I first read post but then I only skimmed the video. Since seen it thoroughly several times and I am surprised at the extent of this parasitic action by birds, I knew vaguely about the cuckoo but not much else about the subject. I think I've learned more from that story on 'Bin chickens than any other HN story in quite a while, it took me down all sorts of alleys, research papers, etc. Initially I wasn't even going to click on this story as there are so many of them on HN and I've only a casual interest in birds from the fact that I see then in my neighborhood. It's interesting really how things turn out (and how one learns things).
