Dawn chorus (birds)
Singing of birds at the start of a day
The dawn chorus is the outbreak of birdsong at the start of a new day. In temperate countries this is most noticeable in spring when the birds are either defending a breeding territory, trying to attract a mate or calling in the flock. In a given location it is common for different species to do their dawn singing at different times.
In some territories where bird life is extensive and birds are vocal, the sound of a dawn chorus may make it difficult for humans to sleep in the early morning.[1][2][3]
