When penguins look up to spot a plane that just passed and made noise,do they loose their balance?

no they are not stupid they turn around

When a plane ascends or descends (ascents are faster, so it is more likely to be a problem then), the pressure changes more rapidly than the mechanisms built into the body can cope with.\n\nThe inner ear is closed off from the outside world by the eardrum. A small tube links it to the back of the nose (the eustachian tube) to equalise pressure; it is normally closed, and its adjustments are normally so small you do not notice them.\n\nIn a plane the pressur change is so fast you can feel it on your ear drum, and you can also feel the "pop" as the tube opens to equalise pressure (yawning helps it to open).

Nope. Turkeys do not look up in order to "see" rain. A turkey's eyes point sideways, so even if a turkey tilted its head backward, it would still be looking to its sides, not up. They tilt their heads sideways to look at something above them. See the link below for a complete debunking of this.

All penguins have a white underside and a dark (mostly black) upperside. This is for camouflage. A predator looking up from below (such as an orca or a leopard seal) has difficulty distinguishing between a white penguin belly and the reflective water surface. The dark plummage on their backs camouflages them from above.

No they don't.  You can go watch the March of the Penguins.  It talks about how they have to starve in the bitter cold protecting their eggs.  They don't actually starve. If they get too hungry they leave the egg.  It's really good.

No.  When you departed the aircraft you body would be travelling at the same speed as the aircraft was travelling.    Wind resistance would slow your body down very quickly but you would still land well ahead of the point in which you jumped out of the plane.

Penguins, like other flightless birds (ostriches and emus) evolved from birds that could fly.\n\n65 million years ago the ancestors of today's penguins flew over the ocean and dove down into the water for food.\n\nOver millions of years, their hollow bones became solid and they could no longer lift themselves out of the water to fly. But, their heavier bones made is easier for them to dive down into the water.

Is it possible that birds misunderstand whales?

to help them see when they're landing?

When it breaks loose it would remind you of the space shuttle taking off.\n\nCoach

That is a good question. Some birds and some insects use the magnetic field of the earth to give them clues for navigation, along with landmarks, and polarization of light etc. My guess is that at first they might be a little confused, but they use multiple clues, so they would soon adjust and learn the new pattern. \n\nAfter all, it flips fairly often on earth's time scale.  Apparently on average it flips every 300,000 years, and  the last flip was 780,000 years ago, so we are a bit overdue at the moment. Obviously, the birds have survived through lots of flips, and movements of the earth and landmarks etc. So they will probably survive the next flip too, but not necessarily without some confusion.

Penguins have a very large amount of body fat for insulation; this enables them to keep their core temperature very high, and allows them to circulate enough blood to their feet to keep them from freezing.

The hummingbird will start moving backwards because the plane is accelerating and unless the bird is moving forward, the bird's inertia will have it attempting to stay in place which is moving backwards.\n\nBut if you're talking about a non-accelerating plane that is moving at a constant velocity then the bird will stay in place.

Think of an airplane as a boat for a moment. You know that a fast-moving boat causes a wake to form behind it. Well, an airplane does this with sound waves. Sound waves propogate ahead of an airplane if it is going slower than the speed of sound. However, if an airplane breaks the sound barrier, the sound waves are pushed together. At first, you hear nothing, and then you hear the sonic boom (the "wake" of the airplane).

It will continue to hover because the air that it's wings are beating against is moving at the same speed as the train. This of course is assuming that the premise requires that all windows are shut and the air is still.

Yes. Penguins appear to have very short legs and no knees because only the lower leg is externally visible. Their knees and upper legs are feather covered, hiding them from view. This also means that penguins never get cold knees\nSee\nhttp://www.penguin.net.nz/faq/faq.html

Dogs with penguins at a close second...something about the way they waddle around...it's pretty cute.
