These colourful avian creatures are attracted to harmonious tones. The better the quality of the music, the more of them you'll attract. They will fly in mesmerising formations as their wings soar through the music carried on the wind. If they feel safe they will land and dance and sing along to the music. They have a large, silky golden tuft at the top of their head that flows down their back. When they bop up and down as they dance and sing, the tuft reacts to the melody. Their feathers come in many varieties of colours. Some say that their colours are dependent on which type of music they like most. Not only are the colors indicators of their preferred music but oddly enough the size of their eyes. It is said that Beep Bop Birds with small beady eyes are more receptive to lower octaves while those with large bulbous eyes prefer higher octaves. Despite their taste in tones all of them have the same row of golden feathers at the edges of their wings. Their size is usually quite small, with short beaks and a plump round body. However, legend says that the more they are exposed to different types of music, the larger they grow in size.
