 The common starling is a noisy bird . Its song consists of a wide variety of both melodic and mechanical @-@ sounding noises as part of a ritual succession of sounds . The male is the main <unk> and engages in bouts of song lasting for a minute or more . Each of these typically includes four varieties of song type , which follow each other in a regular order without pause . The bout starts with a series of pure @-@ tone whistles and these are followed by the main part of the song , a number of variable sequences that often incorporate <unk> of song mimicked from other species of bird and various naturally occurring or man @-@ made noises . The structure and simplicity of the sound mimicked is of greater importance than the frequency with which it occurs . Each sound clip is repeated several times before the bird moves on to the next . After this variable section comes a number of types of repeated <unk> followed by a final burst of high @-@ frequency song , again formed of several types . Each bird has its own repertoire with more proficient birds having a range of up to 35 variable song types and as many as 14 types of <unk> .
