Threatened species - Black-chinned Honeyeater Introduction Until recently it was believed that Australia's mainland birds were secure and abundant. In 1992 a study found that of the 941 species of birds found in Australia, 100 (10.6%) were considered threatened. It is predicted that half of Australia's native land bird species will become extinct by the end of the next century unless dramatic action is taken(a). Description The Black-chinned Honeyeater (Melithreptus gularis) is a small greenish bird, with a black crown, white nape and pale blue skin around the eye. The black chin for which it is named is indistinct.
Status In South Australia, the Black-chinned Honeyeater is considered vulnerable and is limited to two main strongholds; the Mt Lofty Ranges and the South East. The population in the Mt Lofty Ranges has experienced dramatic decline in distribution and abundance in recent decades. Once known in over 80 locations, a year long project in 1994 recorded this honeyeater in only 11 locations with an estimated total population of about 60 individuals(b).They are usually found high up in the canopy of large eucalypts and have a strong churring call. They live in small communal groups, often in association with other bird species, providing benefits from predation and competition for similar food sources. They move in response to the flowering cycles of their food plants and the availability of insects, their primary food source. Habitat Habitat preference is for savannah (grassy understorey) woodland and dry sclerophyll forests dominated by eucalypts and scrub containing silver banksia (Banksia marginata) and native pine (Callitis gracilis). Within the City of Onkaparinga, the Black-chinned Honeyeater is regularly recorded at Christie Creek, Scott Creek Conservation Park and Sturt Gorge Recreation Park.
