What sense organs play a primary role in the life of birds? What is the reason for this?

The most important sense organs in birds that allow them to navigate in their environment are sight and hearing. Sharp vision, quick focus on the sharpness of the image of an object, the ability of the eye to perceive colors and their shades make visual orientation the most important in the life of birds.
Birds also have acute hearing, with the help of which they pick up a variety of sound signals emitted by individuals of their own species, as well as other animals. This enables them to respond appropriately to the sound without seeing the sound source itself.
