This experiment indicates that bird donot use external magnet attached to their head.
As if it is true than bird should reach to thier destination even in windy or cloudy night as magnet direction doesnot depend on these.external factor.
So bird use navigation present in nature like rising of sun from East and sun set in west and in night, direction of polar star and moon.
Now during windy or cloudy night, moon and star are not visible so birds get confused and reached to wrong destination.
Hope it's clear..thanks

Question 18 Not yet answered Marked out of 10.00 Flag question Each spring the buzzards return to Hinkley, Ohio from their wintering grounds in Mexico (this is absolutely true, you can Google it). Remarkably, they make their migration in one continuous flight over about 72 hours, through day and night without a pause. You want to know how they manage to find their way at night and get the clever idea of gluing magnets on the heads of several buzzards...
