what adaptations do chicken bones have that help with flight?
405372
Although chickens are not exactly the paragons of flight ability, there are several adaptations visible in their skeleton that are the legacy of their avian heritage and their ancestor's ability to fly.\n\n(note that the fact that chickens still possess these adaptations even though they are not strong fliers is yet another piece of evidence that evolution is true.  any creationists have any rebuttals?)\n\n- Hollow bones.  Most birds have hollow bones that reduce the mass of their skeleton, making it easier for them to achieve lift.\n\n- Keel-like carina.  Also known as the breastbone, this is the big keel in the KFC breast piece that allows for the attachment of those huge flight muscles that we find so tasty.\n\n- Enlarged flight muscles.  Attached to the carina are the two main muscles, one for bringing the wing in a downbeat and the other for lifting the wing again on the upbeat.  You can see these two muscles when you eat that KFC breast piece too.\n\n- Pillar-like Coracoids.  Bones on either side of the bird's shoulders that act as support for the rib cage, and keep it rigid and not collapsing when the wings flap.  You can see these coracoids on the KFC rib pieces.  On humans, the same bone is much smaller and fused with the scaphoid (shoulder bone).  It's the pointy part of your shoulder that you put in your opponent's solar plexus during a really good shoulder check.\n\n- Lack of teeth.  Birds have lost their heavy jaws full of teeth in favour of lighter keratinous beaks.  They have replaced much of the grinding function with a gizzard filled with easily replaced stones, thus achieving an efficient method of processing food with little biological cost to themselves.\n\n- Forelimbs modified into wings.  This one's pretty obvious.  Chickens have the same arm bones we do, but they're stretched out and fused in various locations to form a wing.  The thumb forms a small wing called the alar that acts almost like the flaps on an airplane wing to control low speed stalls and maneuverability.\n\n- Feathers.  Lightweight, keratinous structures designed to catch and funnel air in such as way as to make flight possible, and they can also act as a thermoregulatory structure to help maintain the high metabolism required for powered flight.  This isn't really a skeletal adaptation, but traces of where feathers attach can be seen on some of the wing bones.\n\n- Pygidium.  The tail of most birds has been reduced to a small nub.  This nub supports the tail feathers (which help maintain flight control with minimal weight), as well as the oil gland used to maintain the hygiene of feathers.  In a cooked chicken, the pygidium is often called the Pope's nose.\n\n- Pelvis.  The long shelf of the bird pelvis provides attachment for the muscles that control tail feather movement, as well as providing support and structure for bipedalism, which is what allows the bird to use its forelimbs for a different mode of locomotion.\n\nThere are probably many more, but that's what I can come up with off the top of my head.

Chickens will eat both grain and small insects.  Most members of the family Corvidae will eat grains, berries as well as insects, small vertabrates and carrion.  Hope that answers your question.

Yes,wild turkeys fly and so do chickens although some breeds fly better than others.Turkeys raised on turkey farms cannot fly. Wild turkeys are relatively weak fliers and will escape on foot if possible; at night, these birds roost in trees. They are capable of achieving speeds of 50 miles per hour (80 kilometers per hour) in flight.http://en.wikipedia.org/wiki/Wild_turkey\n\n\nSome breeds of chickens such as the game and bantam are decent flyers.

Chickens have Talons to dig or scratch for food, but they don't have the same strong gripping talons that say, a hawk would have... Their talons work like hands to keep their balance..

The soup.  The chicken evolved from DNA soup.

i did a small unit in animal behaviour and physiology and from what i remember .. birds have a much narrower vision (acuity of vision) which enables them to detect preys for examples from large distances while flying .. thats all i know, it not ... mm .. that informative.. but i hope it helped .. lol

they have wings, feathers, beaks and all the simalarites a bird has except flying

Physics. Look at the shape of their skull and beak.

No, we couldn't fly if we had wings. We're much to heavy for one thing. Flying birds have hollow bones and many other adaptations for flight (like a "keel" on their breastbone that the flight muscles attach to and specialized respiratory systems). It's a good thing we're smart enough to make things like planes, because that's the only way we're getting in the air.

I think all vertebrates use the same system we do.\n\nbugs have sensory hairs at all their joints. Especially the joints to head and to abdomen tend to be most important for gravity/balance perception (most mass attached). \nIn flying insects the ocelli (three single lens eyes on the top of their head) are thought to help with flight stabilization. Also flying insects have halteres to help with flight stabilization\n\nJellyfish, mussels and other marine invertebrates have statoliths/statocysts. Statoliths are made of a particular dense material and their displacement during acceleration/deceleration can be measured. \n\nI don't think bacteria care, but then they are not animals

Chickens' legs bend the same way as ours do. However, it may appear the opposite because the joint that we can see outside its body is the ankle and not the knee. \nThe femur of birds is relatively short and is inside the body, thus it's not visible. The second segment of the leg is a composite of their tibia and some tarsal bones, and it articulates with the third segment, formed by other tarsal bones fused to the metatarsals. \nHere's a picture of a bird skeleton:\nhttp://www.infovisual.info/02/img_en/056%20Skeleton%20of%20a%20bird.jpg\nAnd a photograph of a real one:\nhttp://a-s.clayton.edu/biology/biol3650l/skeletal/bird/bird-lateral.jpg\n\nNow, the next time you have chicken (or turkey) for dinner, you can have a little dissection entertainment! Bear in mind that the parts of the leg that you eat are the first segment (the largest one, you'll see the femur that was articulated to the axial skeleton) and the second segment (the tibiotarsus, also fleshy because of the muscles). \nIn contrast, the third segment (tarsometatarsus) does not have muscles, but tendons that go from the muscles to the fingers. This part is usually covered with scales and is not included in commercially prepared chickens.\n\nHave fun!

For what category.\nFor leg strength: Ostrich\nFor Wing Strength: Probably the Albatros- they can fly 1000+ miles withouth stopping.\nFor shear wing movement- Hummingbird\nFor neck and head- woodpecker\n\nSo it depends on what you want...

They make their legs more aerodynamic.

Once birds get up in the air, they use two main flying techniques to stay up there.\n\nSoaring: When birds soar, they take advantage air currents to help hold them up. Three kinds of air currents are especially helpful to soaring birds. \n\nThermal air currents develop in places where the air is warmer in one spot than an adjoining area, such as a paved road alongside a snowy field. Even on a very cold day, the sun will heat the pavement at least a few degrees more than the snow. This slightly warmer air is slightly lighter than the colder air, and rises. This rising air current can lift very light objects, like feathers and hollow bones. The birds that most often take advantage of thermals (like the hawks that fly along coastlines) usually have very wide wings and tail. This makes the area of their wings very large compared to their body weight. \nUpdrafts, also called obstruction currents, develop when wind hits an obstruction, like a cliff or a building. The rushing air has to go somewhere, so it goes up, and can carry a bird up with it. Birds who fly on updrafts (like the many hawks that migrate along Hawk Mountain, Pennsylvania) also have very wide wings and tail. \nWind moving toward a bird with spread wings can hold the bird up, thanks to the airfoil shape of the wings. Birds that fly on moving air currents often have long, narrow wings, such as gulls and albatrosses. \n  \n \nFlapping: When birds flap, the stroke of their downbeat moves the wing tips forward and downward. The wingtips make a loop at the bottom of the downstroke, and as the wings move up, the wing tips move upward and backward. In the downstroke, the pressure is higher below the wing than above, causing lift. And as they move forward, the rush of air on their airfoil wings causes more lift. But because flapping birds have smaller wings than soaring birds, they must move forward faster to stay in the air. Most songbirds must fly at least 11 miles per hour to stay up. One scientist calculated that for an ostrich to stay aloft, it would have to take off and maintain a minimum speed of 100 miles per hour. Birds who use their wings to flap more than soar often have smaller wings than soaring birds.

I used to own chickens and roosters. Neither can fly not even a few meters. They are able to jump/flight to there perch and thats about it.\n\nWing to body size ratio prevents their flight.

I don't know about bones, but I know that there have been studies into muscle types of many African tribes, and some have a higher percentage of "fast twitch" fibres in their muscles, mainly those from the south and west of Africa. This may give them an advantage in sprint runs and jumping events, where short spurts of energy are required. However, I don't know why the Kenyans are so good at long distance events. Fantastic to watch though.
