Birds have evolved many physical attributes that contribute to their flying ability. Wings are important, but adjustable tails, large hearts and light bones play critical roles

To fly, birds, like airplanes, move air across their wings. Wings are designed so that air above the wings is forced to move faster than air below the wing. This creates higher pressure under the wings, called lift, which pushes the bird up. Different wing types evolved for different ways of flying. Prolonged flight requires long wings and an ability to soar. Other birds need superior maneuverability. Finches and sparrows have short, broad wings. Faster birds, like hawks have built - in spoilers that reduce turbulence while flying. This allows a steeper angle of attack without stalling.

Tails have evolved for specialized use. The tail acts like a rudder helping birds steer. Birds brake by spreading out their tails as they land. This adaptation allows them to make sudden, controlled stops in essential skill, since most birds need to land on individual branches or on prey.

Flight takes muscle strength. If body builders had wings, they still could not flap hard enough to leave the ground. Birds have large, specialized hearts that beat much faster than the human heart and provide the necessary oxygen to the muscles. The breast muscle accounts for 15 percent of the bird’s body weight. On pigeons, it accounts for a third of their total body weight. Birds carry no excess baggage, they have hollow feathers and hollow bones with struts inside to maintain strength, like cross beams in a bridge. Birds fly to find a prey, escape predators, and attract mates-in other words, to survive.

The Americans with Disabilities Act (ADA) was signed into law in 1990. This law extends civil rights protection to persons with disabilities in private sector employment, all public services, and in public accommodations, transportation, and telecommunications. A person with disability is defined as someone with a mental or physical impairment that substantially limits him or her in a major life activity, such as walking, talking, working, or self-care. A person with a

disability may also be someone with a past record of such an impairment, for example, someone who no longer has heart disease but discriminated against because of that history.

The ADA states that employers with fifteen or more employees may not refuse to hire or promote a person because of a disability if that person is qualified to perform the job. Also, the employer must make reasonable accommodations that will allow a person with a disability to perform essential functions of the job. All new vehicles purchased by public transit authorities must be accessible to people with disabilities. All rail stations must be made accessible, and at least one car per train in existing rail systems must be made accessible.

It is illegal for public accommodations to exclude or refuse persons with disabilities. Public accommodations are businesses and services such as restaurants, hotels, grocery stores, and parks. All new buildings must be made accessible, and existing facilities must remove barriers if the removal can be accomplished without much difficulty or expense.

The ADA also stipulates that companies offering telephone service to the general public must offer relay services to individuals who use telecommunications devices for the deaf, twenty- four hours a day, seven days a week.
