Question

What is the zoological name of the Indian national bird peacock?
a. Passer domesticus
b. Pavo cristatus
c. Columba livia
d. Psittacula eupatria

Answer 1

Hint:
This bird species is fairly prevalent across Southeast Asia species that have an eye-spotted "tail" or "train" of covert feathers that they display as part of a courtship ritual.

Complete answer:
Option A is incorrect. The house sparrow (Passer domesticus) is a species of the Passeridae family, present in most parts of the world. It is a small bird with a typical length of 16 cm (6.3 in.) and 24–39.5 grams of mass. Females and young birds are light brown and grey in color, and males have lighter black, white, and brown lines.
Option B is correct. Peafowl is a common name for three species of birds of the Phasianidae family genera Pavo and Afropavo, the pheasants and their allies. A peacock group is called an "ostentation" or a "muster". Male peafowl is referred to as peacocks, and female peafowl as peahens, while peafowl of either sex is sometimes referred to as "peacocks" in colloquial terms.
Option C is incorrect. One member of the bird family Columbidae (doves and pigeons) is the rock dove, rock pigeon, or common pigeon. From this species came the domestic pigeon (Columba livia domestica which includes around 1,000 different breeds). The color and pattern of the domestic and feral pigeons vary. There are a few differences between males and females. Generally, the species is monogamous, with two squabs (young) per brood. For a while, both parents take care of the kids.
Option D is incorrect. In the year 1800, the French naturalist Georges Cuvier introduced the genus Psittacula. Subsequently, the type species was called red-breasted parakeet. The genus name is a diminutive of the Latin word "Psittacus" for a "Parrot." Most of these parrots have green plumage, with the heads colored to adults. The bill is stout, and the tail is long and sleek.

So, the correct answer is Option B.

Note: The peafowl is native to India but also shows the importance in its history. The peacock is seen as a symbol of royalty in Persia and Babylon and is frequently carved on royal thrones. Nevertheless, there is also an old and prestigious tradition in India that uses the peacock as the emblem of royalty.
