 Contact or social <unk> calls are low @-@ pitched sounds that carry long distances . ' <unk> ' calls are given by individual birds when foraging , and a similar call is given by nestlings that call at an increased rate as the mother approaches the nest . Where there is a high level of social activity , such as during territorial disputes with <unk> , calls are a series of quick , regular , single notes . The noisy miner has a mating display flight song , a soft <unk> of low @-@ frequency notes , given during short undulating flights by the male , and responded to by the female with a low @-@ frequency whistle . The noisy miner is found in open woodland habitats , where it is an advantage to call from the air so as to overcome sound <unk> . Another display call , described as ' yammer ' , is a rapid <unk> series of notes that is uttered during open @-@ bill , wing @-@ waving displays . The noisy miner has a song described as the ' dawn song ' — a communal song of clear <unk> notes emitted in chorus in the early hours of the morning from May through January . The dawn song , which is also sung at dusk , is audible over long distances and features duets that often involve <unk> .
