How does an American Crow reproduce?

Answer 1

Birds have hollow bones, making them lighter. Also, the wing is the shape of an airfoil. And the bird must get enough lift and thrust to overcome gravity and drag. These are the four forces that act on any flying thing.

Answer 2

Exactly as in the huge majority of other birds - they form a pair, they mate, they build a nest, they lay and hatch eggs, they rear the young.

Answer 3

The same way other birds reproduce: by making and laying a clutch of eggs in a nest, then incubating them until they hatch.
