Mountain Thornbill

The Mountain Thornbill (<em>Acanthiza katherina</em>) is a small passerine in the family Acanthizidae, found in the rainforests of northeastern Queensland, Australia. Detailed plumage and behavioral descriptions of this species are limited in the available literature. It is associated with forest habitats, where it typically forages in the mid-story and understory. The species constructs a domed nest (DM type); clutch size is typically 2–3 eggs. Notably, the Mountain Thornbill is currently classified as Vulnerable by the IUCN, indicating a declining population and elevated conservation concern — likely linked to its restricted range and dependence on upland rainforest habitat. Conservation measures and continued monitoring are important for this species.
