Q. Consider the following :

1. Cheetah
2. Pink-headed duck
3. Mountain quail
4. Forest spotted owlet

Which of the above species are on the verge of extinction?
Answer: All of the above
Notes: Some estimates suggest that at least 10 percent of India’s recorded wild flora and 20 per cent of its mammals are on the threatened list. Many of these would now be categorised as 'critical', that is on the verge of extinction like the cheetah, pink-headed duck, mountain quail, forest spotted owlet, and plants like madhuca insignis (a wild variety of mahua) and hubbardia heptaneuron, (a species of grass).
