Question 1 of 5
1. Question
1. In the context of Asian Waterbird Census (AWS), consider the following statements:
1. Bird life International leads this volunteer-based initiative.
2. Its objective is to take stock of migratory bird species visiting the wetlands of Indian subcontinent and Australian continent, particularly during their non-breeding season.
3. The results of this initiative form the basis for identification of Ramsar sites.
How many of the statements given above are correct?Correct
Answer. B
Explanation:
Statement 1 is incorrect: Every January, thousands of volunteers across Asia and Australasia visit wetlands in their country and count waterbirds. This citizen science programme is the Asian Waterbird Census (AWC). The AWC is an integral part of the global waterbird monitoring programme, the International Waterbird Census (IWC), coordinated by Wetlands International.
It runs in parallel with other regional programmes of the International Waterbird Census in Africa, Europe, West Asia, the Neotropics and the Caribbean.
The Asian Waterbird Census first began in 1987 in the Indian subcontinent and has expanded to cover regions of Japan, Southeast Asia and Australia.
Statement 2 is correct: The census has the following objectives:
• to obtain information on an annual basis of waterbird populations at wetlands in the region during the non-breeding period of most species (January), as a basis for evaluation of sites and monitoring of populations
• to monitor on an annual basis the status and condition of wetlands
• to encourage greater interest in waterbirds and wetlands amongst citizens.
Statement 3 is correct: The information so generated is used to identify wetlands of high importance for waterbirds, and take conservation measures such as designation as Ramsar Sites and Flyway Network Sites, or inclusion as priority wetlands within national programmes.Incorrect

Question 2 of 5
2. Question
2. Consider the following statements:
1. Carbon monoxide (CO) is a toxic gas having a direct impact on the global temperature like carbon dioxide.
2. Tobacco smoke and stubble burning release carbon monoxide in the atmosphere.
3. According to the WHO’s Air Pollution Guidelines 2021, short-term exposure of CO should not exceed 40 µg/m³.
How many of the above statements are correct?Correct
Answer: A
Explanation:
Statement 1 is incorrect: Carbon monoxide (CO) is an odourless, colourless and toxic gas. It is a trace gas in the atmosphere, and it does not have a direct effect on the global temperature, like methane and carbon dioxide do.
• However, carbon monoxide plays a major role in atmospheric chemistry, and it affects the ability of the atmosphere to cleanse itself of many other polluting gases. In combination with other pollutants and sunshine, it also takes part in the formation of lower-atmospheric (“bad”) ozone and urban smog.
• Carbon monoxide has a typical “lifespan” of several months in Earth’s atmosphere.
• The gas eventually reacts with oxygen (O2) to form carbon dioxide (CO2).
• Carbon monoxide indirectly contributes to the buildup of some greenhouse gases in the troposphere.
• It reacts with certain chemicals that would otherwise destroy methane and ozone, thus helping to elevate the concentrations of methane and ozone.
Statement 2 is correct: When carbon-based fuels, such as coal, wood, and oil, burn incompletely or inefficiently, they produce carbon monoxide.
The natural sources of carbon monoxide are:
• Volcanoes
• Bushfires
The anthropogenic sources of CO are:
• Tobacco smoke
• Stubble burning
• Automobile exhausts
• Unvented kerosene and gas space heaters
• Leaking chimneys and furnaces
• Generators and other gasoline powered equipment
• worn or poorly adjusted and maintained combustion devices (e.g., boilers, gas stoves, furnaces)
Statement 3 is incorrect- According to WHO Air Pollution Guidelines 2021, the 24-hour mean (short-term exposure) of CO should not exceed 4 µg/m³.Note: Annual and peak season is long-term exposure, while 24 hour and 8 hour is short-term exposure.
Additional information:
• At low concentrations, the exposure to CO leads to fatigue in healthy people and chest pain in people with heart disease.
• At moderate concentrations, its exposure results into angina, impaired vision and reduced brain function.
• At higher concentrations, the effects of exposure to CO are disastrous as it leads to impaired vision and coordination, headaches, dizziness, confusion, nausea, flu-like symptoms that clear up after leaving home. It is fatal at very high concentrations.
• Carbon monoxide is a relatively unreactive compound, so it doesn’t pose much threat to plants or exposed materials.
• However, the gas is quite poisonous to humans and other air-breathing creatures that need oxygen.
• Haemoglobin, the protein in blood that carries oxygen from the lungs to cells throughout the body, is more than 200 times more prone to bind with carbon monoxide than it is with oxygen. This means that someone who breathes too much CO can have their haemoglobin become saturated with it, making it impossible for the blood to deliver oxygen to their cells.Incorrect

Question 3 of 5
3. Question
3. With reference to India’s biodiversity, consider the following species:
1. Ashambu Laughing Thrush
2. White-bellied Sholakili
3. Andaman Crake
4. Tharosaurus indicus
How many of the above are examples of birds and these are also endemic to India?Correct
Answer: C
Explanation:
Options 1, 2 and 3 are correct: While Ashambu Laughing Thrush, White-bellied Sholakili and Andaman Crake are the endemic birds found in India, Tharosaurus indicus is the name given to the oldest fossil remains of a long-necked, plant-eating dicraeosaurid dinosaur discovered in Jaisalmer, Rajasthan.
A publication, titled “75 Endemic Birds of India”, was recently released on the 108th foundation day of the Zoological Survey of India. It points out that about 5% of birds found in the country are endemic and are not reported in other parts of the world.
Key Highlights of the Publication:
Of the 78 species, three species have not been recorded in the last few decades. They are-
• Manipur Bush Quail (Perdicula manipurensis) listed as ‘Endangered’ by the International Union for Conservation of Nature’s (IUCN) Red List of Threatened Species with its last recorded sighting in 1907.
• The Himalayan Quail (Ophrysia superciliosa) listed as ‘Critically Endangered’ with its last recorded sighting in 1876.
• The Jerdon’s Courser (Rhinoptilus bitorquatus) listed as ‘Critically Endangered’ with its last confirmed sighting in 2009.
The highest number of endemic species have been recorded in the Western Ghats, with 28 bird species. Some of the interesting species recorded in this bio-geographic hotspot are the Malabar Grey Hornbill (Ocyceros griseus); Malabar Parakeet (Psittacula columboides); Ashambu Laughing Thrush (Montecincla meridionalis); and the White-bellied Sholakili (Sholicola albiventris).
Some interesting bird species which are only found in the Andaman and Nicobar Islands are-
• Nicobar Megapode (Megapodius nicobariensis);
• Nicobar Serpent Eagle (Spilornis klossi);
• Andaman Crake (Rallina canningi); and
• Andaman Barn Owl (Tyto deroepstorffi).Incorrect
