@2012 you're right. The big question is: why does it have to fly from Alaska to New Zealand, afterall there's food around the neighborhood.

@quicksand, think more about the time factor. Not the distance. Time, 9 days 9 nights non-stop over oceans, cities, deserts... the bird flies!

@impunity, surely what kind of question! You're wondering to track a bird? How do they track baboons, elephants, rhinos etc. ama according to you it's easy to track something that walks but not that flies?

@wakanyu, there's one bird which flies non-stop too. One brain sleeps while the other works, then fail-over applies.

SUBHANALLAH! PRAISE BE TO ALLAH THE BEST OF MAKER!
