Sulawesi Nightjar

The Sulawesi nightjar is a nocturnal Caprimulgus restricted to Sulawesi and the Sula Islands. It belongs to the nightjar family Caprimulgidae and was described by Ogilvie-Grant in 1894. The opened authoritative summaries did not provide a complete plumage diagnosis or measurements, so these are not reconstructed from photographs. Macaulay Library records confirm birds in lowland forest, while field reports document vocal, perched individuals at Tangkoko (Wikipedia taxonomy; Macaulay Library; Birdquest field report).

It uses lowland forest, forest edge, woodland, open country and mangroves. Ecological datasets classify it as a nocturnal aerial insectivore, taking invertebrate prey in flight. Comparative life-history data report a two-egg clutch, but no incubation or fledging period was available in the opened synthesis. The bird’s pointed-winged proportions indicate sustained flight, although the source’s generic migration label is not treated as evidence of seasonal movement for this island endemic (Oiseaux.net ecological synthesis).
