Answer 1

Hint: All types of birds come under the category of Aves. In addition, all the birds are warmblood animals just like human beings. We know that there are many types of species of birds in this world. However, there exists one small group of birds which is said to the smallest species of the birds in this world.

Complete answer:
According to the research, the Ornithologists stated that the bee hummingbird (which is also known to be Mellisuga helenae) is the smallest bird in the world. They live around Cuba and the Isle of Youth. They weigh less than any birds found on the earth. Thus they are said to be the smallest birds.

The common ostrich (which is also called simply ostrich) are the animals that are categorized under the species of Struthio camelus. One can say that the common ostriches are the species of large flightless bird which are native to certain large areas of Africa.

The Penguins are a group of aquatic flightless birds that are categorized under the species of Pygoscelis papua. These animals live almost completely in the Southern Hemisphere. The bald eagles are the bird that is categorized under the species of Leucocephalus. It is known as the bird of prey and found in North America.

Hence, the correct answer is option (A).

Note: The male bee hummingbirds are said to measure only 57 mm in total length. However, in this weight half of the mass is taken up by the bill and tail and they weigh about 1.6 gm. On the other hand, the females are slightly larger. Thus, we can say that this group is an example of the species of which the females are larger than males.
