Answer 2

Heya friend!

Migratory birds use the position of the sun at sunset to know their position. Migratory birds also use the stars. This has been proved by letting birds fly in a planetarium and changing the stars' position. Another tool is the earth's magnetic field (earth's north and south magnetic poles).
