This allows them to keep their bodies strong while travelling for long hours and days. The Blackpoll Warbler makes its annual trip by staying in the air for 80 to 90 hours without resting. The barbules evolved hooks that interlock to make flat vanes as in current contour feathers. Sometimes bright colors are not good. Blowing faster-moving air above the sheet paper lowered the air pressure above the paper. The entire wingspan has to be at the right angle of attack, which means the wings have to twist (and do so automatically) with each downward stroke to keep aligned with the direction of travel. So the shape of the wing and the ability to move it through the air are the two things needed for bird and plane flight. The transition from flying birds to wing-propelled divers was a gradual process which started around 65 million years ago for penguins, and would have involved an intermediate stage whereby its ancestors could use their wings for both flying in the air and diving/swimming underwater (much as Razorbills, for example, do today).

A Bird's Feet Tell Its Lifestyle. This makes it a very efficient flier, as long as there arent any obstacles in its way. ASU - Ask A Biologist. In birds the fingers are reduced and the forearm is lengthened. A smaller wing loading number means the bird/plane can fly more slowly while still maintaining lift and is more manoeuvrable. As you can see at bottom in the diagram, the pulley is located where three bones the coracoid, scapula, and clavicle (not shown) come together to form the shoulder joint.
