Perdrix grise poussins nourriture les terres agricoles. Une étude de l’université de göttingen montre à quel point les oiseaux ont du mal à trouver de la nourriture sur les terres agricoles, les biologistes lisa doom et claude schalk font un test, dans le cadre d’une expérience et laisse plusieurs poussins de perdrix grise chercher de la nourriture pendant 15 minutes. Les uns dans une prairie diversifié d’autres dans un champ en monoculture les poussins sont pesées avant et après le lâcher dans la prairie l’oisillon trouve très vite des coléoptères, des mouches, des fourmis, avant il peser 29,3 grammes, après l’expérience il en fait 29,7 grammes il a pris 0,4 grammes.
Maintenant la contre preuve dans un champ en monoculture, un champ de blé, l’oisillon dispose aussi de 15 minutes pour manger; mais il a du mal à trouver de la nourriture. Il pesait 28,8, après un quart d’heure seulement le poussin a perdu 0,1 grammes.
Donc, une prairie diversifiée et riche en insecte est riches en nourriture et dans une monoculture il y en a beaucoup moins, le poussin doit dépenser beaucoup trop d’énergie pour trouver de la nourriture, concrètement dans un champ de monoculture ils meurent de faim. Dans la nature des milliers, voire des millions de poussins meurent de faim au printemps et en été, le nombre de perdrix grise a diminué de 94 % depuis 1981.
