Crescent Honeyeater - Distribution and Habitat

Distribution and Habitat

There are records of scattered populations of the Crescent Honeyeater on the Central Tablelands, the Mid North Coast, and in the Hunter Valley of New South Wales, and it is widespread in the areas of New South Wales south of Dharug National Park and east of Bathurst. In Victoria it is widespread across an area from the NSW border south west to Wallan with scattered populations recorded further west. It is widespread in Tasmania, except in the north-east part of the state where it is more sparsely distributed. It is restricted to sclerophyll forest in eastern South Australia, where isolated populations have been recorded in the Mount Lofty Ranges and on Kangaroo Island. Local influxes have occurred outside its normal range in response to changes in habitat. Recorded population densities range from 0.3 birds per hectare (0.1 per acre) near Orbost, to 8.7 pairs per hectare (3.4 per acre) in Boola Boola State Forest, also in Victoria.

While the Crescent Honeyeater occupies a wide variety of habitats including coastal heath, rainforest, wet sclerophyll forest, mountain forest, alpine woodland, damp gullies and thick tea-tree scrub, they all demonstrate its preference for dense vegetation. It has been frequently recorded in wet sclerophyll forest dominated by eucalypts and with a thick mid-story and understory of shrubs such as blackwood, silver wattle, Cassinia, Prostanthera, and Correa. At higher altitudes it occurs in alpine heathlands and in woodlands of stunted eucalypt or conifers.

The movements of the Crescent Honeyeater within its range are incompletely known. There is widespread evidence of seasonal migration to lower altitudes in cooler months, yet a proportion of the population remains sedentary. Autumn and winter migration to the lowland coastal areas is seen in southern Tasmania, where it is not unusual to see it in urban parks and gardens, as well as Gippsland, and the New South Wales Central and South Coast. In the Sydney region, some birds appear to move down from the Blue Mountains to Sydney for the cooler months, yet others remain in either location for the whole year. It is only seen in alpine and subalpine areas of the Snowy Mountains in warmer snow-free months (mainly October to April). Other populations of Crescent Honeyeaters follow a more nomadic pattern of following food sources; this has been recorded in the Blue Mountains and parts of Victoria.
