Sulawesi Serpent Eagle

The Sulawesi serpent eagle is a medium-sized forest raptor 46–54 cm long with a wingspan of roughly 105–120 cm. It belongs to Spilornis and is represented by two subspecies: the nominate form on Sulawesi and nearby southern islands, and sulaensis in the Sula group. The species is endemic to this Indonesian island region. The opened sources did not provide a sufficiently detailed plumage diagnosis, so identification features are not reconstructed from photographs (Wikipedia and IOC taxonomic account; AZA raptor plan).

It is a diurnal, perch-hunting carnivore of forest, mainly in the lowlands and hills, with ecological datasets placing records broadly around 300–1,000 m. The diet is classified as vertebrate prey with some carrion. Comparative life-history data report a one-egg clutch, about 35 days of incubation and approximately 60 days to fledging, though these values should be checked against the underlying study before regional use. Indonesian habitat summaries also record wooded hills and mountains (Oiseaux.net synthesis; PT Vale fauna guide).
