The blue-faced honeyeater (Entomyzon cyanotis), also colloquially known as the Bananabird, is a passerine bird of the honeyeater family, Meliphagidae. It is the only member of its genus, and it is most closely related to honeyeaters of the genus Melithreptus. Three subspecies are recognised. At around 29.5 cm (11.6 in) in length, the blue-faced species is large for a honeyeater. Its plumage is distinctive, with olive upperparts, white underparts, and a black head and throat with white nape and cheeks. Males and females are similar in external appearance. Adults have a blue area of bare skin on each side of the face readily distinguishing them from juveniles, which have yellow or green patches of bare skin.
Found in open woodland, parks and gardens, the blue-faced honeyeater is common in northern and eastern Australia, and southern New Guinea. It appears to be sedentary in parts of its range, and locally nomadic in other parts; however, the species has been little studied. Its diet is mostly composed of invertebrates, supplemented with nectar and fruit. They often take over and renovate old babbler nests, in which the female lays and incubates two or rarely three eggs.
The blue-faced honeyeater is found from the Kimberleys in northwestern Australia eastwards across the Top End and into Queensland, where it is found from Cape York south across the eastern and central parts of the state, roughly east of a line connecting Karumba, Blackall, Cunnamulla and Currawinya National Park. It has a patchy distribution in New South Wales, occurring in the Northern Rivers and Northern Tablelands regions, and along the coast south to Nambucca Heads. To the south, it is generally absent from the Central and South Coast, and is instead found west of the Great Divide across the South West Slopes and Riverina to the Murray River. It is common in northern Victoria and reaches Bordertown in southeastern South Australia, its range continuing along the Murray. It is also found in the Grampians region, particularly in the vicinity of Stawell, Ararat and St Arnaud, with rare reports from southwestern Victoria. The species occasionally reaches Adelaide, and there is a single record from the Eyre Peninsula. The altitude ranges from sea level to around 850 m (2,790 ft), or rarely 1,000 m (3,300 ft).
In New Guinea, it is found from Merauke in the far southeast of Indonesia's Papua province and east across the Trans-Fly region of southwestern Papua New Guinea. It has also been recorded from the Aru Islands.
The blue-faced honeyeater appears to be generally sedentary within its range, especially in much of the Northern Territory, Queensland and New South Wales. However, in many places (generally south of the Tropic of Capricorn), populations may be present or absent at different times of the year, although this appears to result from nomadic, rather than seasonal, migratory movements. Around Wellington in central New South Wales, birds were recorded over winter months, and were more common in autumn around the Talbragar River. Birds were present all year round near Inverell in northern New South Wales, but noted to be flying eastwards from January to May, and westwards in June and July. In Jandowae in southeastern Queensland, birds were regularly recorded flying north and east from March to June, and returning south and west in July and August, and were absent from the area in spring and summer.
They live throughout rainforest, dry sclerophyll (Eucalyptus) forest, open woodland, Pandanus thickets, paperbarks, mangroves, watercourses, and wetter areas of semi-arid regions, as well as parks, gardens, and golf courses in urban areas. The understory in eucalypt-dominated woodland, where the blue-faced honeyeater is found, is most commonly composed of grasses, such as Triodia, but sometimes it is made up of shrubs or small trees, such as grevilleas, paperbarks, wattles, Cooktown ironwood (Erythrophleum chlorostachys) or billygoat plum (Terminalia ferdinandiana). One study in Kakadu National Park found that blue-faced honeyeaters inhabited mixed stands of eucalypts and Pandanus, but were missing from pure stands of either plant.
