How do the migratory bird's chicks find their way home back?

Question

The migratory birds's chicks find their way back to their native destination once they grown up & even some time they join with it's own group. How does it possible?

Answer 1

Scientists are only beginning to uncover the very physicalities of a bird that makes it built for mass migrations. Some believe that they use the electromagnetic fields surrounding the planet, as do theorize with other animals, for navigation. Hence, they may use this information on instinct. Not just learnt instinct, but genetic instinct, passed on through evolution and natural selection and encoded in the DNA.

Much like in the sense of the salmon fish, being that they are also migratory animals. They are able to find the very stream and river their parents spawned them. A remarkable ability.

In my opinion, there is an area in the brain that controls our navigational senses. We, humans, have far more complex and advanced brain functions, and we have the ability to realize our abilities and its functions and connect them accordingly. Other animals that possess navigational senses on the other hand have far more simple brain chemistries, resulting in meek, instinctual behaviors like mass migrations.

Migratory birds find their way through eons of repetitive actions learned, enhanced, and evolved over the generations; hence, it becomes instinct. Yet, their brains can go no further than instinct itself (they will not ask themselves why they do it).

Reproduction and the need to survive is what compells most living things to be constantly on the move. All the while, nature - the environments around us - shapes our very DNA every second that passes, as it shapes itself.

I'm staring at my cockatiel right now and I see those eons of evolution fade away as she witnesses what the meaning of domestication is. And as each chick that it bears the more ignorant they become of their biological codes. Yet, not enough time given to the extent that if I decide to release them in the wild that they will die. Their instincts will just instantly kick in; wild-side activated and eager to mate.

Evolution is the answer, my friend. It is Gaia's (Mother Nature) reflection on the water. She is time's sister, and she will be as constant as time as well.

Maybe if birds started looking at the sky once in a while, as they are going about their migratory ways, they might start to wonder about life itself; kind of like ourselves. Then, maybe one day they will really rule the skies. ; )

Answer 2

All the living creature in this world has got some basic instinct.

Although we see them with less then our abilities but they are born with their sixth sense which only helps them to live their life.

As for the migratory bird they clearly feel the earths magnetic fields from far up the ground which helps even a new born chick to fly back to the destination. More over they never live alone rather than a group which is their stronger social guideline in helping fly their zone.

Answer 3

Birds have an inherent knowledge of where they need to go. Experiments have shown that they use the possition of the stars to orient themselves. In the experiment ther hatchlings hatched in an enclosed estuary where the stars constellations were projected in the wrong orientation and the birds migrated in the direction of the projected stars, and not the actual direction they should have gone. Another experiment has shown that birds can see polarized light. There is a band of polarized light that is visible to us if we look through a special polarized filter. The bird's eye's contain this filter built in. The band of polarized light is in different possitions durring the course of the year, and not only helps to guide the migration, but also acts to trigger the migration. The birds know that when the band is in a specific place it is time to migrate. Weather cues also trigger migration, pressure, temperature and wind currents all aid in the catalysis of migratory behavior. Exactly how the information is transfered from generation to generation, no one knows, but we do have these clues as to how it works.

Answer 4

There are a number of theories as to how this is accomplished. Many scientists think it may have something to do with the Earths electromagnetic fields but they have not been able to identify organs for such detection. I am more inclined to think that once an action is accomplished a physical template is formed which makes the action more easily accomplished in future. The basis of this is a hypothesis called formative causation and is related to morphic resonance. For more on formative causation and morphic resonance see Dr. Rupert Sheldrake's publications.

Answer 5

instinct plus fear of bird flu

Answer 6

Nobody actually knows. It still is a big mystery.

Answer 7

earth magnetic poles

Answer 8

It is called instinct!

Answer 9

A GPS dude, what else...duh!
