The owl kills its prey using these talons to crush the skull and knead the body. [29] The crushing power of an owl's talons varies according to prey size and type, and by the size of the owl.
Raptors may have to pursue mobile prey in the lower part of their visual field, and therefore do not have the lower field myopia adaptation demonstrated by many other birds.

The feathers making up this disc can be adjusted by the bird to alter ...
