Am I crazy? This doesn't actually say anything about their guidance system? Just that its "genetic"?
> In a groundbreaking new study published in the journal Science, researchers have found that a combination of genetics and environment determines where migratory birds fly to for the winter.
I guess the "guidance system" is not located in any organ or individual bird, but as a kind of accumulated collective knowledge. Perhaps the term was misleading, since it's a metaphor relating to a mechanism in individual airplane, rocket, etc.

If it is mainly genetic then a bird raised in captivity should be able to track the route somewhat accurately, that's groundbreaking

So the Earth's magnetic poles are not involved at all then?
They surely use magnetics ss their compass. This research uncovered the map they're using while traveling, so to speak.
