("Homing" is not the same as migration. It suggests that pigeons can find their way home when taken by train or truck to some far-distant place and then released. But homing surely has some of the same mechanisms; migration does, and so can give clues to how it works.) It seems that as pigeons get fairly close to their home, they first pick up general smells that tell of bird dwellings-perhaps the general tempting stink of ammonia. As they get nearer, the smells become more specifically pigeon-like. Finally, as they get very close, they recognize the very particular odor of their own flock in its own space. More and more evidence is revealing that humans, too, have a wonderful awareness of odor, even if they do not consciously recognize it, such that they find particular men or women attractive or disgusting according to their primitive substances such as sweat no doubt a cooling thought for human beings have risen above such things.
