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).
