Birds, butterflies, and whales make annual journeys of thousands of kilometers. They rely on any thing to find their way?
Thanks for sharing.
Animal navigation is the ability of many animals to find their way accurately without maps or instruments. Birds such as the Arctic tern, insects such as the monarch butterfly and fish such as the salmon regularly migrate thousands of miles to and from their breeding grounds, and many other species navigate effectively over shorter distances.
Dead reckoning, navigating from a known position using only information about one's own speed and direction, was suggested by Charles Darwin in 1873 as a possible mechanism. In the 20th century, Karl von Frisch showed that honey bees can navigate by the sun, by the polarization pattern of the blue sky, and by the earth's magnetic field; of these, they rely on the sun when possible.
William Tinsley Keeton showed that homing pigeons could similarly make use of a range of navigational cues, including the sun, earth's magnetic field, olfaction and vision. Ronald Lockley demonstrated that a species of small seabird, the Manx shearwater, could orient themselves and fly home at full speed, when released far from home, provided either the sun or the stars were visible.

Dear Ahmed
Animals migrate for a variety of reasons. Migration is a behavioral adaptation that helps animals survive. Scientists aren't really sure exactly how some animals figure out how to get to where they are going. They think that some animals use landmarks like rivers and streams to find their way. Other animals may navigate by the position of the sun and stars. Scientists think some animals use smell to figure out where they are going. And there are some species that may use the Earth's magnetic field to navigate. However they do it, migration is a behavioral adaptation that has evolved over time to help animals survive.

I dear say, only the Creator knows how they do it. Just adding my lay person's view on the subject.
Many thanks,
Debra

Dear Ahmed Al mayahi,
Birds, butterflies and whales make an annual trip at a distance of thousands of kilometers. They rely on cues such as stars and magnetic fields, but the details remain unclear.

Dear,
Thank you for the invitation, but I do not know enough to respond. Success in your questioning!
