The major difference between a bird and a fly is that both belong to different phyla.
Bird
Phylum: Chordata
They have a four chambered heart.
Have hollow bones so that they can fly. (exceptions present of course, e.g., Ostrich)
Insect
Phylum: Arthropoda
They have an open circulatory system.
No bones.
I think these are few of the major differences. There are many more, you may find more if you browse through any grade 11 Biology book.
Tks.
But,that question is just kidding
