Migratory Birds & Wildlife — Set 9

Correct Answer: B. Spectacular Amur Falcon migration stop-over where millions roost

Doyang Reservoir in Nagaland is famous for hosting the world's largest single gathering of Amur Falcons, with millions of these small raptors roosting there during their migration from breeding grounds in China and Russia to wintering grounds in South Africa. The spectacular sight was documented in 2012. Though the local Naga community hunted them previously, after conservation awareness efforts the community now protects them. The Amur Falcon migration through Nagaland is considered one of the world's most dramatic wildlife spectacles.

Correct Answer: B. Using electronic devices (radio/satellite tags) attached to animals for remote monitoring of location and behaviour

Biotelemetry in wildlife tracking involves attaching electronic transmitters (radio tags, satellite tags, GPS loggers) to animals to remotely monitor their location, movements, and behaviour. For migratory birds, satellite tracking has revealed previously unknown migration routes, stopover sites, and wintering areas. GPS-tagged Bar-headed Geese, Great Knots, and other species have revealed detailed migration pathways through India. This technology has revolutionised migration research by providing real-time tracking of individual birds across their entire annual cycle.

Correct Answer: B. Andaman Islands

The Andaman Woodpigeon (Columba palumboides) is endemic to the Andaman Islands, found nowhere else in the world. It is a large forest pigeon restricted to the dense tropical forests of the Andaman archipelago. Like many Andaman endemic birds, it evolved in isolation from mainland Indian birds and shows closer affinities with Southeast Asian species. The Andaman Islands have high bird endemism with numerous endemic species and subspecies. These birds face threats from forest loss and invasive species.

Correct Answer: B. Study of periodic biological events like migration timing, breeding seasons, and their relationship to climate

Phenology in bird migration studies refers to the study of periodic biological events like migration arrival and departure dates, breeding season onset, and their relationship to climate variables like temperature and rainfall. Climate change is causing phenological shifts in many migratory species — birds arriving earlier in spring as temperatures warm. Monitoring these phenological changes is important for understanding the effects of climate change on migratory birds. Long-term datasets from ringed bird data and citizen science observations are crucial for phenological analysis.

Correct Answer: B. Arctic Russia and Siberia

The Tundra Bean Goose (Anser serrirostris) breeds in the arctic tundra of Russia and Siberia and winters in parts of South Asia including India. These geese migrate in family groups through Central Asian flyways to winter in Indian wetlands. They are one of the larger goose species visiting India. Large wetlands in Gujarat, Rajasthan, and the Gangetic plains host wintering goose flocks. Hunting and disturbance during winter and migration are the main threats to these geese.

Correct Answer: B. Ecotourism focused on bird watching, generating revenue for local communities near bird habitats

Birding Tourism (or Bird Tourism) is nature-based tourism focused on bird watching that generates significant economic benefits for local communities near bird sanctuaries and important bird habitats. India's birding tourism is growing rapidly, with both domestic and international birders visiting sites like Bharatpur, Chilika, Kaziranga, Thattekad, and Eaglenest in Arunachal Pradesh. Birding tourism creates incentives for conservation and provides livelihoods for local guides, boat operators, and accommodation providers near bird-rich habitats.

Correct Answer: B. Long-distance migrants travel thousands of kilometres between breeding and wintering areas; short-distance migrants move shorter distances, often altitudinally

Long-distance migrants travel thousands of kilometres between their breeding and wintering areas — such as the Siberian Crane flying from Siberia to India or the Arctic Tern from Arctic to Antarctic. Short-distance or partial migrants move shorter distances — often altitudinally within the Himalayas (moving from higher elevation summers to lower elevation winters) or between adjacent regions. Many Indian hill birds are altitudinal migrants. Understanding these distinctions is important for designing appropriate conservation strategies for different migratory species.

Correct Answer: B. Common Kinglet or Ruby-crowned Kinglet (weighing about 6 grams) — similar very small species migrate globally

Some of the world's smallest migratory birds weigh only 5-10 grams — including species like the Common Kinglet (Regulus regulus) found in Europe-Asia and its close relatives. In India, the Fire-capped Tit and Yellow-bellied Fantail are among the smallest migratory visitors. These tiny birds undertake remarkable long-distance migrations despite their diminutive size, building up fat reserves that can equal their body weight. The physiological challenges of long-distance migration for tiny birds are even more remarkable than for large species.

Correct Answer: B. Unusual migration in the wrong direction, often by young birds, sometimes bringing vagrant species to unexpected locations

Reverse Migration occurs when birds, typically young individuals, migrate in the wrong direction — opposite to the normal migration direction. Young birds programmed to fly southwest in autumn might mistakenly fly northeast (reverse direction), ending up in unexpected locations. This creates vagrant sightings of species far from their normal range. Reverse migration is one of the mechanisms that introduces new species to areas outside their normal range and has been important in range expansion of some species over time.

Correct Answer: B. Annual tribal festival promoting culture and wildlife conservation, with hornbill representing Naga culture

The Hornbill Festival in Nagaland celebrates and promotes Naga tribal culture with the Great Hornbill (Buceros bicornis) as its symbol, representing cultural strength and majesty in Naga traditions. The festival simultaneously promotes wildlife conservation awareness — tribal communities that once used hornbill feathers for ceremonial headdresses are now turning to sustainable alternatives as conservation awareness grows. The festival has become a major cultural tourism event. This positive link between cultural identity and conservation benefits hornbill protection.
