The reserve was declared in 1992, and is the primary nesting site of several endangered species, several of which are endemic, including the Hatutu Marquesan Warbler (Acrocephalus mendanae postremus) and the Marquesas Ground Dove (Gallicolumba rubescens).
Kubary discovered at least four bird species -- the Samoan Wood Rail (Gallinula pacifica), the Mariana Crow (Corvus kubaryi), the Caroline Islands Ground Dove (Gallicolumba kubaryi), and the Pohnpei Fantail (Rhipidura kubaryi) -- as well as numerous insects, among them the Paradise Birdwing (Ornithoptera paradisea).
The Mindoro Bleeding-heart (Gallicolumba platenae) (Filipino: kulo-kulo) is bird native to the Philippines.
This area, which also includes Mount Calavite, is a habitat of various flora and fauna, such as the rare Mindoro Tamaraw and the critically endangered Mindoro Bleeding-heart (Gallicolumba platenae).
Its taxonomic affiliation is uncertain but at its first scientific discussion by Johann Georg Wagler in 1829 it was classified into the genus Gallicolumba (which includes Ground Doves and Bleeding-hearts); its closest relative is possibly the Santa Cruz Ground Dove.
