Wildlife and Tigers in India

Beetles produce a low buzzing or droning sound, especially when flying. The other options are incorrect: boom is not an insect sound, bleat is a sheep/goat sound, and howl is associated with wolves or dogs.

As per the latest tiger census in India, there were approximately 1,411 tigers remaining in the wild. This was a critical conservation milestone that showed recovery from earlier drastic declines. The other options are incorrect numbers.

Hippopotamuses make a distinctive loud, booming call known as a bellow or wheeze-honk. Mewing, howling, and braying are sounds associated with cats, dogs, and donkeys respectively.

India's tigers face multiple threats: historical hunting for sport and products, habitat loss from logging/encroachment, and ongoing poaching pressure. All factors (A, B, and C) contribute to the endangered status, making option D correct and comprehensive.

Parrots are famous for their ability to talk and mimic human speech, which is their most characteristic sound. While parrots can scream when distressed, 'talk' is the primary sound they're known for. Snort is made by horses, and whistle is more typical of birds but doesn't capture the parrot's defining ability.

At the start of the 21st century (around 2000), India had approximately 40,000 tigers historically, though the actual wild population by then had declined significantly. This question tests knowledge of wildlife population statistics in India.

Project Tiger was launched by the Government of India in 1973 to protect and conserve the declining tiger population. This landmark conservation initiative established tiger reserves across the country and is considered one of India's most successful wildlife conservation programs.

Of the approximately 3,500 tigers remaining in the wild globally, about 1,400 are found in India, which is home to the largest tiger population in the world due to its extensive tiger reserves and conservation efforts under Project Tiger.

India has established 37 tiger reserves (sanctuaries) under Project Tiger to provide protected habitats for the conservation of tigers and their ecosystems. These reserves are spread across various states in India.
