Why do they sing in the dark?

[TerryH]

Wild birds can sing anytime in the whole day of twenty four hours. So we can say mainly the birds that sing during night is because of the disturbance which can be because of winds, rain, predators or the light which they take as the day.

You are right. I love the way they sing. Very relaxing. Right now it is quite tense condition in our locality due to corona virus and in these conditions listen them singing is some relief
