Answer: (A) Great Indian Bustard, Musk Deer, Red Panda and Asiatic Wild Ass

The correct answer is the group where ALL species are endangered:

Option (a) — Great Indian Bustard (Critically Endangered), Musk Deer (Endangered), Red Panda (Endangered), Asiatic Wild Ass (Near Threatened/Endangered) — all are threatened species.

The other options can be eliminated because they contain common species:

  • (b) includes Cheetal (deer) and Blue Bull (Nilgai) — both are abundant in India.
  • (c) includes Rhesus Monkey — very common.
  • (d) includes Blue Bull, Hanuman Langur, and Cheetal — all common species.

Elimination strategy: if you see Cheetal, Blue Bull, Nilgai, Rhesus Monkey, or Hanuman Langur — these are NOT endangered.

Answer: (a).

Why this was asked

Great Indian Bustard is critically endangered with fewer than 200 birds remaining, making it one of India's most threatened species.

UPSC uses common species like Cheetal, Blue Bull, and Rhesus Monkey as trap options since students often assume all wild animals are endangered.

The question tests ability to distinguish between truly threatened species versus abundant wildlife that students encounter in news or national parks.

Critically Endangered Species in India

Environment Great Indian Bustard

Critically Endangered Species in India: UPSC Key Species

Must know

Great Indian Bustard is India's most critically endangered bird with less than 200 individuals

Musk Deer is endangered due to hunting for musk pods used in perfumes

Red Panda is endangered and found only in Eastern Himalayas

Good to know

Asiatic Wild Ass survives only in Gujarat's Rann of Kutch

What Makes a Species Endangered

IUCN Red List categorizes species from Least Concern to Extinct. Critically Endangered means extremely high risk of extinction, Endangered means very high risk. India has over 2,500 animal species under threat.

Protected Areas & Conservation

Great Indian Bustard - Protected in Desert National Park (Rajasthan) and Blackbuck National Park (Gujarat)

Red Panda - Found in Singalila National Park (West Bengal) and Namdapha (Arunachal Pradesh)

Musk Deer - Protected under Wildlife Protection Act 1972, trade banned under CITES

Asiatic Wild Ass - Indian Wild Ass Sanctuary in Little Rann of Kutch is the only habitat

Exam traps

Cheetal (Spotted Deer) appears in 2 wrong options - it's abundant, not endangered

Blue Bull (Nilgai) appears in 2 wrong options - it's common across India

Rhesus Monkey is widespread and Least Concern, not endangered

Hanuman Langur is common in forests and urban areas - not threatened

Don't confuse Red Panda with Giant Panda - Red Panda is native to India

Common Wildlife Species (Not Endangered)

Environment Cheetal Blue Bull Rhesus Monkey Hanuman Langur

Common Indian Wildlife: UPSC Elimination Strategy

Must know

Cheetal (Spotted Deer) is abundant in Indian forests and national parks

Blue Bull (Nilgai) is India's largest antelope, widespread and increasing

Rhesus Monkey is extremely common, used in medical research

Good to know

Hanuman Langur is widespread across India, considered sacred

Why These Species Are Common

These species are adaptable to human-modified habitats and have stable populations. They often benefit from agriculture and are not hunted due to religious protection or lack of commercial value.

Common Species vs Endangered

Species

Conservation Status

Population Trend

Habitat

Cheetal

Least Concern

Stable/Increasing

Forests, grasslands, parks

Blue Bull (Nilgai)

Least Concern

Agricultural areas, scrublands

Rhesus Monkey

Least Concern

Urban, rural, forest areas

Hanuman Langur

Least Concern

Stable

Forests, urban areas, temples

Kashmir Stag

Critically Endangered

Increasing slowly

Dachigam National Park only

Swamp Deer

Vulnerable

Stable in reserves

Grasslands, swampy areas

UPSC Elimination Clues

Agricultural pests like Blue Bull are never endangered - farmers consider them problems

Temple animals like Hanuman Langur receive protection and food from humans

Research animals like Rhesus Monkey are bred in captivity and widely distributed

Park-common species like Cheetal are easily spotted by tourists in most national parks

Exam traps

Blue Bull = Nilgai - same animal, different names, always common

Don't confuse Kashmir Stag (endangered) with Cheetal (common deer)

Swamp Deer is vulnerable but Cheetal is abundant - know the difference

Hanuman Langur ≠ Lion-tailed Macaque - Hanuman common, Lion-tailed endangered

IUCN Red List Categories

Environment

IUCN Red List: Conservation Status Categories

Must know

IUCN Red List is the global standard for assessing extinction risk of species

Critically Endangered means extremely high risk of extinction in wild

Categories range from Least Concern to Extinct

Global Conservation Authority

International Union for Conservation of Nature (IUCN) maintains the Red List since 1964. It evaluates species based on population size, rate of decline, geographic range, and fragmentation.
