Yellow-plumed honeyeater
The yellow-plumed honeyeater (Ptilotula ornata) is a species of bird in the family Meliphagidae. It is endemic to Australia, where it inhabits temperate forests and Mediterranean-type shrubby vegetation. The yellow-plumed honeyeater was previously placed in the genus Lichenostomus, but was moved to Ptilotula after a molecular phylogenetic analysis, published in 2011, showed that the original genus was polyphyletic.[2][3] DescriptionThe yellow-plumed honeyeater is a medium-sized honeyeater with a relatively long, down-curved black bill, a dark face and a distinctive, upswept yellow neck plume.[4] It has an olive-green head, with a faint yellow line under the dark eye, grey-green upperparts, and heavily streaked grey-brown underparts.[4] Young birds have a yellow bill base and eye-ring.[4] Similar species include purple-gaped honeyeater,[5] grey-fronted honeyeater[4] and fuscous honeyeater.[5][4] CallThe song is a loud, clear, three-note chier wit chier, often performed before dawn, and by males during display flight.[6] DistributionThe yellow-plumed honeyeater is endemic to southern mainland Australia, from western New South Wales and Victoria, through South Australia to south-west Western Australia.[4] Ecology and behaviour_(8079669037).jpg) The main habitat type for yellow-plumed honeyeater is mallee.[5] They occupy a broader range of habitat in the west of their range, including dry eucalypt woodland and eucalypt open-forest.[6] They occasionally occur outside their usual habitat, such as in Acacia and Callitris woodland,[6] and seasonally in flowering red ironbark forest, flowering grey box-yellow box woodland.[5] They occur in sedentary, colonial groups, which may relocate in response to harsh conditions.[6] They are noisy and conspicuous, and will jointly defend nesting or feeding territories, by engaging in communal wing quivering displays.[6] DietYellow-plumed honeyeaters are mainly insectivorous, foraging actively mainly in outer and upper foliage, branches and trunks of eucalypts, and taking insects on the wing by hawking. [5] They also feed opportunistically on nectar,[6] including from various mallee eucalypts, yellow gum, grey box, red ironbark, and box mistletoe.[5] ReproductionYellow-plumed honeyeaters build an open, cup-shaped nest suspended by the rim from foliage or from a thin fork of mallee eucalypts and other small shrubs.[4] Nests are made from wool, green grass and spider webs, and lined with wool, grasses, plant-down and brightly-coloured feathers.[4] Both parents feed the young, sometimes with the assistance of helpers.[4] Yellow-plumed honeyeater nests are parasitised by fan-tailed cuckoos, pallid cuckoos, Horsfield's bronze-cuckoos and shining bronze-cuckoos.[4] Conservation actionsConservation statusThe species is listed under the IUCN Red List of Threatened Species as a species of Least Concern.[1] Protected areasThe yellow-plumed honeyeater occurs in several protected areas, including:
