Acoustic monitoring reveals a diel rhythm of an arctic seabird colony (little auk, Alle alle)
Abstract The child-like question of why birds sing in the morning is difficult to answer, especially in polar regions. There, in summer animals live without the time constraints of daylight, and little is known about the rhythmicity of their routines. Moreover, in situ monitoring of animal behavior...
