Thông tin:
The California condor is another accidental victim of human activity. These huge birds with bald heads and big beaks weigh up to fourteen kilos, have a wingspan of up to two metres and can live as long as sixty years. They play an important role in the ecosystem by feeding on dead animals, thus preventing the spread of disease. Reintroduced into the wild after becoming extinct, other than in captivity, they are now under threat once more because of chemical pesticides introduced into the food chain and lead poisoning from the ammunition used to kill the animals they feed on. (Chim điêu California là một nạn nhân tình cờ khác của hoạt động con người. Những chú chim khổng lồ này, có đầu hói và mỏ lớn, nặng đến 40 kg, có sải cánh rộng đến 2 m và có thể sống tới 60 năm. Chúng đóng vai trò quan trọng trong hệ sinh thái qua việc ăn xác động vật, từ đó ngăn lây lan bệnh dịch. Được đưa trở lại tự nhiên sau khi tuyệt chủng, ngoài việc nuôi nhốt, chúng hiện đang bị đe dọa lần nữa do thuốc trừ sâu hóa học được đưa vào chuỗi thức ăn và nhiễm độc chì từ đạn được sử dụng để giết những động vật mà chúng ăn.)
