Range extension for the Dwarf Sparrowhawk

Darren O'Connell

Biodiversity monitoring work can often be disheartening. Typically, we end up documenting a decline in whatever species we are working with. So it’s always a pleasure to have the opportunity to deliver some positive news. A stroll with my collaborator Adi Karya around his university campus in Kendari city provided an unexpected opportunity to do just that. Halu Oleo University has quite a unique green space, a 65 ha patch of city forest, an island of jungle in a sea of urban development. While picking our way through a particularly muggy gully we saw the flash of a small raptor in the canopy, giving me just enough time to snap off a shot before it skulked away. Thankfully the photo was clear enough for a species ID (particularly as the humidity in the forest killed my camera for the rest of the field season!). It turned out to have been a Dwarf Sparrowhawk. This elusive raptor is a classified as a Near Threatened montane specialist, with its stronghold in the mountains of central and northern Sulawesi. Therefore our record from the coastal lowland city of Kendari, in southeastern Sulawesi, is several hundred kilometres in distance, and metres in elevation, from the Dwarf Sparrowhawk’s supposed core range.

This record (published in the latest issue of BirdingASIA), along with previous research by Operation Wallacea and TCD Zoology scientists, suggests that the Dwarf Sparrowhawk may be much more widespread and have a wider habitat tolerance than previously thought. We hope future research by our partners in the region will confirm the healthy state of the Dwarf Sparrowhawk and lead to an upgrade of this elusive raptors conservation status.
