The white-plumed honeyeater (Ptilotula penicillata) is a species of small passerine bird endemic to Australia. The species is common around water, and they are often seen in backyards and suburbs with vegetation cover. First described by the English naturalist John Gould in 1837, the specimen he examined came from the "interior of New South Wales". The specific epithet penicillata derives from the Latin word penicillis, meaning 'brush tip', referring to the white plume across the side of the neck, its distinguishing characteristic. The rest of the bird is mainly olive-coloured. This white-plumed honeyeater was photographed in Glen Davis, New South Wales.Photograph credit: John Harrison
