Taxonomy
Scientifically known as Cacomantis passerinus, the Grey-bellied Cuckoo belongs to the family Cuculidae in the class Aves. Their close relatives include other cuckoos and coucals found throughout Asia and Australasia. These birds share numerous characteristics with their family members but stand out due to their unique plumage and calls.

As the name suggests, the Grey-bellied Cuckoo has a distinctive grayish belly with a darker shade of grey covering its back and wings. Its throat and breast are white with fine dark streaks. The bird features a slender body with long wings and a slightly forked tail. With its bright yellow eyes encompassed by a black eyestripe, the Grey-bellied Cuckoo is an attractive sight for birdwatchers.
Habitat
Grey-bellied Cuckoos prefer habitats ranging from open woodland to subtropical or tropical mangrove forests. They can also be found in shrublands, cultivated areas, or gardens across Asia – from India and Sri Lanka to Southeast Asia, including Indonesia and the Philippines.
Diet
These enigmatic birds are primarily insectivores feasting on caterpillars, moths, grasshoppers, crickets, beetles, and other insects. Occasionally, they may consume small vertebrates like lizards and even other birds' eggs, highlighting their diverse diet.
Presence in Nepal
In Nepal, the Grey-bellied Cuckoo has a seasonal presence, generally occurring between March and November.

One intriguing aspect of the Grey-bellied Cuckoo’s behavior is its brood parasitism strategy. Like other cuckoos, this species lays its eggs in other birds' nests – particularly those of warblers and babblers – letting the unsuspecting hosts incubate and rear their young. This remarkable adaptation ensures that Grey-bellied Cuckoos can focus on foraging and evading predators without the added responsibility of raising offspring.
The Grey-bellied Cuckoo is an alluring species that captures the interest of bird lovers with its stunning appearance, unique behaviors, and haunting calls. Discovering more about this remarkable bird only adds to the appreciation of nature's diversity and complexity. Now equipped with knowledge about its taxonomy, physical features, habitat, diet, and curious presence in Nepal, you'll revel in the chance to spot one of these awe-inspiring creatures during your next birdwatching adventure.
