Alondra Común

Célebre en la literatura y poesía europea por su complejo y melodioso canto interpretado en vuelo durante espectaculares vuelos de exhibición, la alondra común (Alauda arvensis) asciende verticalmente cientos de metros sobre campos abiertos, praderas y brezales de Europa y Asia mientras produce un torrente ininterrumpido de canto que puede durar hasta una hora. Los machos pueden producir más de 700 frases de canto distintas. Antaño enormemente abundante en los campos europeos, las poblaciones de alondras han disminuido más del 70% desde 1970 debido a la intensificación agrícola.
