The first singing begins well before the sky lights up. One type of bird that is always seen to start singing even before most parts of the environment have started waking up is the European robin and its cousins in North America. In most cases, one might think that it is strange to hear a bird sing at such an early hour, when there is very little light.
As per the findings of some scientists, the reasons why robins tend to sing so early include a variety of factors, biological ones, environmental ones, and some behavioral ones. As per some scientific papers on the topic, it makes sense that robins begin singing so early because it gives them some significant benefits.
