Birds have a hollow bone construction that makes their skeleton light. Lots of individual bones are joined together to reduce the number of moveable joints- this makes it easier to be an efficient flying machine.

This is how different types of bird wings have adapted over time.

Elliptical = adapted for forest or shrub habitat where maneuvering is important. (Galliformes, many Passerines).

High Speed = adapted for feeding on wing or very long- distance migration; flattish profile. [Shorebirds, Falcons, Hummers, Swallows, & Swifts].

Long and narrow, adaptive for soaring (Pelagic birds.)

High Lift = adapted for carrying heavy loads. Deep curvature (Hawks & Eagles, Cranes).
