Question

list any four flight adaptation of birds​

Answer 1

Most birds are well adapted for flight. Their
bones are hollowed out to make them light, their bodies are stream-lined for
decreased air resistance. Their forelimbs have evolved into feathered wings and
their breast bone is enlarged for attachment of strong muscles used in flying.
Their respiratory systems are also larger and more efficient than that of their
mammal counterparts, as flying requires greater amounts of energy than running
or walking.
