Question

List the characteristics of birds that allow them to fly.

Answer 1

Birds have the following characteristics that allow them to fly:

1. Feathers that are light and smooth.
2. A beak, rather than hefty, bone jaws and teeth.
3. A sternum (an expanded breastbone) for attaching flight muscles.
4. Light bones - birds' bones are hollow, with air sacs and thin, small cross-sections to strengthen them, reducing the force of gravity.
5. A rigid skeleton form strong attachments and powerful flying.
6. A streamlined body that aids in lowering the force of drag.
7. Wings that aid in lifting forces.
