A certain margin during the morning twilight is ever a specific incentive for individual species of songbirds.

When a bird begins with the singing, is strongly influenced by the ambient brightness and thus from the time of sunrise, which in turn depends on the season and the geographical location.

Graphical representations of a bird watch are often found on forest education or nature trails.

A singing at special times allows better localization of different individuals of the species, the spatial allocation of song of a certain bird male within a species becomes clearer when its voice is not lost in the chorus of any other, but can be heard in competition with similar.
