laverca

Celebrada na literatura e poesia europeia por seu complexo e melodioso canto entoado durante espetaculares voos de exibição, a cotovia-comum (Alauda arvensis) sobe verticalmente centenas de metros acima de campos abertos, pradarias e charnecas da Europa e Ásia, produzindo um torrente ininterrupto de canto que pode durar até uma hora. Os machos podem produzir mais de 700 frases de canto distintas. Outrora extremamente abundante nos campos europeus, as populações de cotovias diminuíram mais de 70% desde 1970 devido à intensificação agrícola.
