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 …

Biak Gerygone

The Biak Gerygone is a near-threatened small warbler-like bird endemic to Biak and Supiori islands in West Papua, Indonesia. It has yellowish underparts and olive-brown upperparts typical of gerygones. It forages actively in forest canopy, gleaning insects from leaves, and is restricted to its small island range.
