Habitat

These great eared nightjar species inhabit dense tropical forests, secondary forests and moist lowland forests. They prefer areas near flowing waters and clearances in the forest cover.

Diet and feeding habits

These nightjars are nocturnal or crepuscular and feed on insects, beetles and moths.

Breeding

The breeding season of these nightjar species is between January and May in South India and Malaysia. The nest is a scraped hollow on the ground. A single egg is laid and both the parents take turns to incubate. The nightjar parents camouflage chick among leaf litter on the forest floor.

Distribution

The great eared nightjar subspecies L. m. macropterus is distributed in Indonesian islands (Talaud Islands, Sulawesi Islands, Banggai Islands, Sangihe Islands and Sula Islands). The subspecies L. m. bourdilloni is distributed in Southwest India. The subspecies L. m. macrotis is distributed in more than eleven islands of Philippines. The subspecies L. m. cerviniceps is distributed in Northeast India, Bangladesh, South China and southeast Asia. The subspecies L. m. jacobsoni occurs in Simeulue Island located off Northwest Sumatra in Indonesia.

Movement and migration patterns

These great eared nightjar species are non-migratory and are resident birds. They may make local movements for feeding and breeding.

Conservation status and concerns

The global population of these nightjar species has not been quantified. The overall population trend is considered to be stable. It has extremely large range and hence considered not "Vulnerable" to extinction.

The IUCN (International Union for Conservation of Nature) has categorized and evaluated these nightjar species and has listed them as of "Least Concern".
