This came to me in an email from Australian Hearing






January 28 marked the start of the new Chinese New Year and Year of the Rooster

A good sense of hearing is important for roosters and chickens when trying to distinguish between different kinds of vocalisations including those between a mother hen and her brood.

The feathers that surround the ear help to channel sound into the ear canal. Like mammals, birds have an outer ear, a middle ear, and an inner ear. Birds are able to perceive sounds more quickly than can humans. They are also adept at pinpointing the source of a sound by assessing the lag time between the sound's arrival at either side of the head.
