Summary The ranges next to the town of Wyndham support one of the largest known populations of the endangered Gouldian Finch, breeding in old-growth eucalypt savannas. The IBA also supports populations of the range-restricted Yellow-rumped Mannikin and seven species restricted to the tropical savanna biome.
Site description The IBA consists of hills next to the town of Wyndham in north-east Western Australia. The IBA boundary currently only includes the nature reserve on the Bastion Hills which is known to support breeding Gouldian Finches, although the reserve's current protection status is unknown. The water-holes around the town of Wyndham itself are not mapped. Further fieldwork is likely to discover additional breeding areas in more distant hills. The general region of the north Kimberley (including along the Ord, Dunham, Keep, Drysdale and Gibb and Durack Rivers and the Ellenbrae, Campbell and Dawn Creeks) probably supports pockets of breeding Gouldian Finches but this is the best-documented site and supports the largest known population. The IBA is dominated by gently sloping ranges with sandstone outcrops, with an exceptionally high density of cavity-bearing eucalyptus trees suitable as Gouldian Finch nest-sites, and seeding native grasses for Gouldian Finch food. The area is characterised by its prevalence of old-growth eucalypt stands providing natural hollows suitable for Gouldian Finch nesting. The close proximity of Wyndham township also provides a consistent supply of drinking water sources. Wyndham has a population of about 800 people. The mean minimum temperature is 17 Celsius in July, mean maximum temperature is 40 Celsuis in November and mean annual rainfall is 780 mm, mostly between November-March.
