Challenger’s Red-and-blue Lory (Eos histrio ssp. challengeri)
Challenger’s Red-and-blue Lory was restricted to the island of Miangas, northeast of Sulawesi, Indonesia, or from Nenusa Island. The subspecies, however, is known only from the type specimens and is not accepted by every ornithologist.
It differed from the other two subspecies by the lesser extent of the blue feathers, especially on the head.
***
The Red-and-blue Lory still exists on three of the Talaud Islands, Indonesia where an endemic subspecies, the Talaud Red-and-blue Lory (Eos histrio ssp. talautensis Meyer & Wiglesworth), occurs.
The species is highly threatened with extinction.
