Sun Yuan-hsun, who has been researching birds for over a decade, says that researchers have discovered female birds on their nests spending all their time trying to peck off their transmitters. The birds lost interest in looking for food, so that their chicks suffered retarded growth or even died. Spoiling the view?
研究鳥類超過十年的孫元勳就說，曾有研究人員發現母鳥在巢裡終日試圖用嘴摳掉身上的發報器，無心於覓食，小鳥因此成長緩慢，甚至造成死亡。
