The wattled ploughbill was long thought to be related to the whistlers (Pachycephalidae), and shriketits (formerly Pachycephalidae, now often treated as its own family). In particular the wattled ploughbill and crested shriketit share a similar large bill. Genetic studies have shown that these birds are not closely related, and as instead more closely related to the sittellas. Because of its genetic and morphological uniqueness, in 2014 Richard Schodde and Leslie Christidis placed it in its own monotypic family Eulacestomidae. [2]

The wattled ploughbill is a monotypic species, meaning it has no accepted subspecies. A subspecies clara has been proposed, but it is not reliably distinct from other birds in this species.[3]


It is approximately 12.5 to 14 cm (4.9–5.5 in) , olive-brown songbird with a strong, thick, wedge-shaped black bill. It weighs 19–22 g (0.67–0.78 oz). The sexes are different. The male has black underparts, an almost golden forehead, black wings with golden scapulars, and a pair of large circular pink wattles on the cheek. The female has olive green plumage and pale olive below. Only the adult male has wattles.[3]

Distribution and habitat

The wattled ploughbill is distributed and endemic to central mountain ranges of New Guinea.


The diet consists mainly of insects. The species feeds from the forest floor to up to 10 m (33 ft), from the understory to the mid-level of the forest. It particularly favours groves of bamboo as a micro-habitat for feeding. It forages on branches and twigs, gleaning insects from the surface and prising off bark to expose prey. The species will readily join mixed-species feeding flocks.[3]


Widespread throughout its large range, the wattled ploughbill is evaluated as least concern on the IUCN Red List of Threatened Species.

List of bird genera

List of bird genera concerns the chordata class of aves or birds, characterised by feathers, a beak with no teeth, the laying of hard-shelled eggs, and a high metabolic rate.

List of birds of Indonesia

Indonesia, with its vast islands, tropical weather and rainforests is one of the world's richest and most important country in term of biodiversity. In addition to the many resident birds, of which the most important are the 380 endemics, a considerable number of migratory species winter in the country to escape their northern breeding grounds.

The list will be growing, since many new species are discovered every year in many unexplored areas of Indonesia. In December 2005, a honeyeater Melipotes carolae was discovered in Foja Mountains among other new animal and plant species.

In June 2011 there are 123 Indonesian bird species threatened, 18 were categorized as endangered while 31 others endangered and 74 vulnerable.

List of birds of Papua New Guinea

This is a list of the bird species recorded in Papua New Guinea. The avifauna of Papua New Guinea include a total of 781 species, of which 76 are endemic, one has been introduced by humans and eighteen are rare or accidental. Twenty-eight species are globally threatened.

This list's taxonomic treatment (designation and sequence of orders, families and species) and nomenclature (common and scientific names) follow the conventions of The Clements Checklist of Birds of the World, 6th edition. The family accounts at the beginning of each heading reflect this taxonomy, as do the species counts in each family account. Introduced and accidental species are included in the total counts for Papua New Guinea.

The following tags have been used to highlight several categories. The commonly occurring native species do not fall into any of these categories.

(A) Accidental - a species that rarely or accidentally occurs in Papua New Guinea

(E) Endemic - a species that is native only to Papua New Guinea

(I) Introduced - a species introduced to Papua New Guinea as a consequence, direct or indirect, of human actions

List of least concern birds

The Sibley-Monroe checklist was a landmark document in the study of birds. It drew on extensive DNA-DNA hybridisation studies to reassess the relationships between modern birds.
