1. “Ornithology” is the scientific study of which of the following?
Correct answer: C. Birds — Ornithology is the branch of zoology that deals specifically with the study of birds.
2. Which of the following birds is a flagship species for the success of India’s wetland conservation efforts, especially at Keoladeo National Park?
Correct answer: C. Siberian crane — Its historic wintering at Keoladeo highlighted the global significance of the wetland, though it no longer regularly visits.
3. Which adaptation in birds is most directly associated with reducing body weight for flight?
Correct answer: C. Pneumatic (hollow) bones — Air-filled bones reduce body weight while maintaining structural strength, aiding powered flight.
4. Which of the following statements about bird migration is INCORRECT?
Correct answer: C. All migratory birds travel strictly along the north–south axis — Many routes are complex, including east–west movements and loop migrations.
5. The “Great Indian bustard”, a critically endangered bird, is primarily associated with which type of habitat?
Correct answer: C. Arid and semi-arid grasslands — It depends on open grassland ecosystems of western and central India.
6. Which bird is the State Bird of India’s national capital territory, Delhi?
Correct answer: B. House sparrow — The house sparrow has been declared the State Bird of Delhi to highlight urban biodiversity and conservation concerns.
7. In birds, the “crop” is primarily involved in which of the following functions?
Correct answer: B. Temporary storage and softening of food — The crop is an outgrowth of the esophagus that stores and moistens food before digestion.
8. Birds are considered important bio-indicators. Which of the following is a correct pair of bird group and the environmental factor they most effectively indicate?
Correct answer: B. Waterfowl – Wetland health — Diversity and abundance of waterfowl correlate strongly with the ecological condition of wetlands.
9. In India, the decline of vulture populations has been largely attributed to which veterinary drug found in livestock carcasses?
Correct answer: B. Diclofenac — The NSAID diclofenac causes kidney failure in vultures feeding on treated cattle carcasses.
10. Which of the following statements about bird reproduction is correct?
Correct answer: B. Birds lay amniotic eggs with calcareous shells — The hard shell and membranes enable terrestrial reproduction.
11. Which Indian bird species is listed under Schedule I of the Wildlife (Protection) Act, 1972 and is also critically endangered on the IUCN Red List?
Correct answer: C. Great Indian bustard — It receives the highest legal protection and is one of the most threatened large birds in the world.
12. Which of the following birds is primarily a “nectar feeder” and thus an important pollinator?
Correct answer: B. Sunbird — Sunbirds have slender, curved beaks adapted to feed on floral nectar and aid pollination.
13. Which of the following best explains why birds excrete uric acid instead of urea?
Correct answer: B. Uric acid can be stored in the body without toxicity — It is relatively insoluble, conserves water, and suits egg-laying and flight adaptations.
14. Which of the following bird-related conventions or agreements specifically focuses on conservation of migratory waterbirds and their habitats along flyways?
Correct answer: D. Bonn Convention and related flyway initiatives — The CMS (Bonn Convention) and its instruments specifically address migratory species, including many birds, along flyways.
15. “BirdLife International” works primarily in which of the following domains?
Correct answer: B. Global bird and habitat conservation — It coordinates global efforts for bird conservation and identifies Important Bird and Biodiversity Areas (IBAs).
16. In the context of Indian wetlands, which of the following is a major threat to waterbird diversity?
Correct answer: B. Conversion of wetlands for agriculture and real estate — Habitat loss and fragmentation severely impact waterbird populations.
17. Which of the following bird groups is most important for natural biological control of agricultural pests?
Correct answer: C. Insectivorous birds — They consume large numbers of insects, reducing pest populations in agro-ecosystems.
18. Which of the following combinations is correctly matched?
Correct answer: B. Weaver birds – Pendulous woven nests on branches — Male weaver birds construct intricate hanging nests using grass and fibers.
19. Which feature of the avian respiratory system makes it more efficient than that of mammals?
Correct answer: C. Unidirectional airflow through parabronchi aided by air sacs — This ensures continuous and efficient gas exchange during both inhalation and exhalation.
20. Which of the following pairs is correctly matched with respect to flyways used by migratory birds visiting India?
Correct answer: A. Central Asian Flyway – Covers parts of Eurasia and Indian subcontinent — Many migratory waterbirds reaching India use this flyway.
