He made a comment earlier regarding the swallows that they return "infallibly" to the same place. They don't of course, some 'return' to other places, and some 'return' to places that don't allow them to reproduce for whatever reason, predation or lack of food or whatever, and thus die out, and still others do not return at all, so their lines die out. The ones that do return to somewhere they can breed are the ones that survive and the ones that Asyncritus gets to talk about doing things 'infallibly'.
