Describe the modifications seen in birds for flight. Include modifications in as many body systems as possible. What will be an ideal response?


Concepts to Consider: Birds are light, and many body systems show reductions to reduce
weight; their bones may be hollow; their respiratory system is particularly efficient to meet
the energetic demands of flight; uric acid is excreted often; their senses are well developed,
which allows precise flight; many migrate great distances to facilitate reproduction in optimal
habitats.
