The yellow-billed malkoha is a species of cuckoo in the family Cuculidae. It is endemic to Sulawesi, Indonesia. Its natural habitat is subtropical or tropical moist lowland forests.
Region
Sulawesi (Wallacea)
Typical Environment
Occurs in primary and secondary lowland and hill forests across Sulawesi and some adjacent islets. It favors forest edges, riverine strips, and vine-tangled subcanopy, and will also use selectively logged or older secondary growth. The species is typically found from the midstory to subcanopy, moving methodically along branches and lianas. It occasionally visits agroforests and plantations near intact forest.
Altitude Range
Sea level to 1200 m
Climate Zone
Tropical
Ease of Keeping
Beginner friendly: 1/5
A non-parasitic cuckoo, the yellow-billed malkoha creeps through foliage rather than pursuing long flights. It specializes in hairy caterpillars and other large insects that many birds avoid. Its long graduated tail aids balance as it forages in the subcanopy. The species is confined to Sulawesi and nearby islets of Indonesia.
Temperament
secretive and deliberate
Flight Pattern
short rapid wingbeats with brief glides between trees
Social Behavior
Usually seen singly, in pairs, or small family groups, and sometimes joins mixed-species flocks in the subcanopy. Nests are shallow twig platforms placed in dense foliage. Both parents participate in nest defense and chick rearing.
Migratory Pattern
Resident
Song Description
Vocalizations are soft and low, including mellow coos and clucking notes delivered from cover. It may give a series of nasal calls or chuckles when moving with foraging parties.
Plumage
Mostly slaty-gray to olive-brown upperparts with paler underparts and a long, graduated tail often showing pale tips. The throat is paler and contrasts subtly with the darker breast. Feathers appear smooth and close-fitting, aiding a sleek, elongated profile.
Diet
Feeds mainly on large insects such as caterpillars, grasshoppers, mantises, and beetles, and will also take spiders and small lizards on occasion. It methodically gleans prey from leaves, twigs, and clusters of vines. Hairy or noxious caterpillars are consumed and handled skillfully.
Preferred Environment
Forages in the midstory and subcanopy of lowland and hill forests, especially along edges and gaps. Often works through vine tangles, along lianas, and near fruiting or flowering trees that attract insect prey.
