Changes

'''Drakes and Cobs''' (male swans) have an enlarged osseous bulla on the left side of the syrinx which acts as a resonator. '''Songbirds''' have a complex set of syringeal muscles. Sexual dimorphisms occurs in songbirds, with the males of the species usually producing a more complex birdsong, which directly relates to the size of the area of the brain responsible for song. '''Parrots''' have a thick [[Tongue - Anatomy & Physiology|tongue]] which allows them to make sounds similar to humans. Sound travels from the syrinx and is modified in the throat, [[Tongue - Anatomy & Physiology|tongue]] and mouth in parrots.
