Feather development occurs in the epidermal layer of the skin in birds.It is a complicated process involving many steps. Once the feathers are fully developed, there are six different types of feathers: contour, flight, down, filoplumes, semiplumes, and bristle feathers.
Females communicate to males by clicking their wings, a signal that they are ready for mating. After mating, females lay eggs in dead branches of small trees or shrubs; using an ovipositor to slit a branch and insert eggs. Later, the eggs hatch and nymphs drop to the soil and quickly burrow and feed on the roots of plants.

The mechanics of an avian's wings involve a complex interworking of forces, particularly at the shoulder where most of the wings' motions take place. These functions depend on a precise balance of forces from the muscles, ligaments, and articular cartilages as well as inertial, gravitational, and aerodynamic loads on the wing. [4]
