These large-tailed nightjar species have low forest dependency. They inhabit various ecosystems. They inhabit deciduous and open evergreen forests, farmlands, fallow agricultural fields, parks, rural gardens, plantations and degraded forests. They also inhabit submontane and montane moist subtropical or tropical forests, subtropical forests, dry tropical shrubland, temperate shrubland, subtropical or tropical mangrove forests, dry savanna, wetlands and temperate forests. They occur in altitudes from 0 to 2700 meters.Diet and feeding behavior

The breeding season is from March to June in northern Thailand and is from January to September in Malaysia. They lay one or two eggs directly on bare ground.Migration and movement patterns
These large-tailed nightjar species are sedentary and resident birds in their range.Conservation and survival
The global population size of the large-tailed nightjar (Caprimulgus macrurus) is not quantified. The overall population size of these nightjar species is considered to be stable. Throughout its ranges it is common and very abundant. Their generation length is 5.6 years.The large-tailed nightjar does not approach the thresholds for being Vulnerable either under the range size criterion or under the population trend criterion or under the population size criterion. Habitat loss is the main threat to the survival of these species.
