Question

Which of the following birds lives in the polar region?

Answer 1

They are a group of flightless marine birds. In the Southern Hemisphere, they live almost entirely, with only one population, the Galápagos, located north of the equator. About half of their lives are spent on land, the other half on the sea.

Complete answer:
While almost all species of penguins originate in the Southern Hemisphere, they are not only found in cold climates, such as the Antarctic. Currently, too far south, only a few species of penguin live. In the temperate region, several species are present, but one species, the Galápagos penguin, lives near the equator.
Larger penguins occupy colder regions among the current penguins, whereas smaller penguins are normally found in temperate or even tropical climates. Some extinct creatures, being as tall or heavy as an adult human, achieved enormous sizes. These were not limited to Antarctic regions; on the contrary, there was a high diversity of subantarctic regions, and at least one giant penguin occurred in an area approximately 2,000 km south of equator 35 mya, in a climate clearly warmer than today.

Additional information:
Hen: A type of domesticated fowl, a subspecies of the red junglefowl (Gallus gallus), is chicken (Gallus gallus domesticus). Chickens, with a total population of 23.7 billion as of 2018, are one of the most common and widespread domestic animals. Up from more than 19 billion in 2011. There are more chickens in the world than any other bird or domesticated fowl.
Eagle: The Eagle is the common name of the Accipitridae family for many large birds of prey. Eagles belong, not all of which are closely related, to several groups of genera. The majority of the 60 eagle species are from Eurasia and Africa. Only 14 species can be found outside this region—2 in North America, 9 in Central and South America, and 3 in Australia.
Sparrow: The house sparrow (Passer domesticus) is a bird of the Passeridae sparrow family, found in most parts of the globe. It is a small bird that has a typical length of 16 cm (6.3 in) and a mass of 24–39.5 g (0.85–1.39 oz). The pale brown and grey colors of the females and young birds and the brighter black, white and brown markings of the males. The house sparrow is one of approximately 25 species in the Passer genus and is native to most of Europe, the Mediterranean Basin, and much of Asia.
So, the correct answer is ‘(d) Penguin’.

Note: In reality, the Wings of the Penguin have become flippers. This implies that on land they are somewhat clumsy, but can really travel underwater. In fact, ducking and weaving are so graceful that their behavior in the water looks like a bird in air flight. When a Penguin dives into the water, it can reach a speed of up to 12 kilometers per hour and some can reach up to 27 km / h when in high gear. As far as diving is concerned, larger penguins will go deeper for up to 22 minutes.
