A. Streptopelia
B. Pavo
C. Columba
D. Eudynamis

Answer 1

Hint: The Indian nightingale bird shows a parasitic type of population interaction known as brood parasitism. The cooee call is well known in these birds and it is what earned them the name of Indian nightingale.

Complete answer:
The Indian nightingale is the common name given to Eudynamys scolopaceus. It is more commonly known as koel. It belongs to class Aves under phylum Chordata of the animal kingdom. The name Indian nightingale was given to them because these birds even sing during the night time.

Additional Information:
Few features shown by the organisms belonging to class Aves are as follows:
> These are warm-blooded organisms and their forelimbs are modified into wings.
> The body is streamlined or boat-shaped and divided into head, neck, trunk, and tail.
> Non Glandular skin is seen, only oils glands or uropygial glands are present in the tail portion.
> Jaws are modified in beak and the absence of teeth is seen in these organisms.
> An epidermal sheath known as rhamphotheca is present on the teeth.
> The gastrointestinal system has an additional chamber known as crop and gizzard. Both of these are modifications of the oesophagus.
> A cloaca with three chambers and a single cloacal aperture is present.
> Four chambered hearts are present.
> Monocondylic skull and bifid ribs are seen.
> Nucleated, oval, and biconvex RBCs are observed.

So, the correct answer is,” Indian nightingale is Eudynamis.”

Note: The singing voice of birds is produced by a special organ known as syrinx. These are uricotelic organisms and in marine birds, the excretory product is known as guano. An important point to remember is that in almost all mammals except camel and llama RBCs are non-nucleated, but in organisms belonging to class Aves the RBCs are nucleated.
