Correct Option (A):
All four species listed – Ceylon frogmouth, Coppersmith barbet, Gray-chinned minivet, and White-throated redstart – are avian species.
The Ceylon frogmouth (Batrachostomus moniliger) is a nocturnal bird primarily found in the Western Ghats of India and Sri Lanka.
The Coppersmith barbet (Psilopogon haemacephalus) is a common resident bird across the Indian subcontinent, recognized by its distinctive metallic call.
The Gray-chinned minivet (Pericrocotus solaris) is a small passerine bird inhabiting the Himalayan region and northeastern parts of India.
The White-throated redstart (Phoenicurus schisticeps) is a migratory bird species observed in the higher altitudes of the Himalayan ranges.
These birds play crucial ecological roles, including insect control, seed dispersal, and pollination, contributing to ecosystem health.
