The white-plumed honeyeater (Ptilotula penicillata, formerly Lichenostomus penicillatus) is a medium-sized passerine of the family Meliphagidae (honeyeaters) endemic to mainland Australia. Its key identifying characteristics are a primarily olive-grey body and yellow face, a slightly down-curved bill and its white distal neck-plumes from which it takes its name. White-Plumed Honeyeaters exhibit a preference for woodlands and riparian areas and have a very strong association with River Red Gums. They exhibit a small seasonal migration from ranges to lower areas in winter. Today the species is most commonly seen through Victoria, South Australia and New South Wales, but is also found in regions of Western Australia and the Northern Territory. They are often seen in gardens and backyards with vegetation cover.
Honeyeaters are most diverse group of passerine birds on continental Australia and the White-plumed honeyeater is one of the most common honeyeaters of urban areas throughout much of Australia. The first formal description of Ptilotula penicillata was by John Gould in 1837 who named it Lichenostomus penicillatus and placed it within the Ptilotula group within the Meliphagidae...
