Flying Bird (Noun)
Meaning
Birds having keeled breastbones for attachment of flight muscles.
Classification
Nouns denoting animals.
Examples
- Most flying birds have powerful chest muscles that account for up to 30% of their total body weight, with some species, such as the pigeon, having an even higher percentage.
- The flying bird's keeled breastbone is particularly deep, providing a large surface area for the attachment of flight muscles.
- Attachment of the flying bird's flight muscles to its skeleton is made possible by the keeled breastbone, which forms a ridge running along the center of the sternum.
- In addition, the wishes of flying birds have highly efficient respiratory systems that provide oxygen to the flight muscles quickly and efficiently.
- The fossil record indicates that the earliest known flying bird, Archaeopteryx, possessed a keeled breastbone similar to that of modern flying birds.
