I report observations on the nesting behaviour of Natewa Silktail Lamprolia klinesmithi on the Natewa Peninsula, Vanua Levu, Fiji. Field work in June–August 2018 located four nests of which two were closely monitored. Nest attentiveness was very low (42.58% and 42.05% of total observation time spent at the nest), as was provisioning rate (35.29% of nest visits with food) in part due to uniparental care but possibly also in response to nest predation and fecundity-survival trade-off by the parent. Nest site and habitat were significantly different from historical records pertaining to the closely related (previously conspecific) Taveuni Silktail L. victoriae. The close proximity of nests and presence of six individuals in the nesting area poses questions concerning the species' breeding strategy. The paucity of data surrounding the ecology of Lamprolia and the lack of formal protective legislation on the Natewa Peninsula highlight the need for research into this endemic and globally threatened species.
