Question

adaptations of migratory birds​

Answer 1

HELLO

RAM RAM JI

Birds that migrate typically have longer wings than birds that don't migrate. Their wings have a higher ratio of wing length to wing breadth than non-migratory species or resident species like the Northern Cardinal. This adaptation reduces the relative impact of drag (air resistance), resulting in greater force that opposes the pull of gravity).

Feathers also factor in. A bird's outer primary feathers work with its inner primaries to provide forward thrust in flapping flight. In migrants, these outer primary feathers are often longer, giving the wing a shape that's pointed.

Answer 2

Adaptations: Migration: How The shape of a bird's wing is one of the physical adaptations that aids in a bird's migration. Birds that migrate typically have longer wings than birds that don't migrate. Their wings have a higher ratio of wing length to wing breadth than non-migratory species or resident species like the Northern Cardinal.
