It is getting less, but soon, as soon as spring comes around, we will wake up to birds singing again at dawn. It is not just cliché, birds really do sing mostly – and most prominently – in the morning. But why do they sing at all?
Almost half of the world's bird species are songbirds. Of course, all bird species make noises, but we differentiate between calls and songs. Calls are direct and sharp; they are short, simple noises. The song however can be two to six seconds long and are repeated over and over.
The first ones to starts as early as 4am are Blackbirds, Robins and Wrens. One of the theories around the early morning tweeting is that it is not yet bright enough to forage and there is therefore time for singing. In cities, the theory is that mornings are beneficial for birds because their songs travel further while they would be covered by urban noise. Their voices can travel in dense woodlands.
