TheWyndham Important Bird Area comprises a 28 km2 tract of land in the north-east of theKimberley region ofWestern Australia. The site lies in the Bastion Hills close to the town ofWyndham, a port on the West Arm of theCambridge Gulf. It is an important site forGouldian finches.
The site is characterised by gently sloping ranges, vegetated withtropical savanna woodlands and grasslands, withsandstone outcrops. The woodland has a high density ofcavity-bearingold-growtheucalypts suitable as finch nest-sites; the grassland provides food for the birds; and the proximity of Wyndham provides reliable sources of drinking water. The area has atropical monsoon climate with a mean minimum temperature of 17 °C in July, a mean maximum of 40 °C in November, with the mean annual rainfall of 780 mm falling mainly from November to March.[1]
The site has been identified as anImportant Bird Area (IBA) byBirdLife International because it supports the largest known population ofendangered Gouldian finches. It also contains populations of,northern rosellas,white-gaped,yellow-tinted andbar-breasted honeyeaters,silver-crowned friarbirds,masked andlong-tailed finches andyellow-rumped munias.[2]
ElevenEstrildidae finch in the FamilyPloceidae are distributed in the Kimberley region of Western Australia. Commercial finch trapping in the Kimberley, principally around Wyndham, commenced in 1897. By 1901 finches were trapped around Wyndham and shipped overseas to Europe in consignments of approximately 5,000 by the persons trapping them. All Kimberley finches were partially or fully protected from 1902 under the Western AustralianGame Act, 1892. Commonwealth Customs regulations first introduced in 1911 failed to curb large scale exports by private finch traders until 1932. One of the largest commercial traders of wild caught Kimberley finches in the late 1920s and 1930s was the South Perth Zoo which exploited customs' law to export for 'scientific and educational purposes'. Licenses to trap finches in the Kimberley were first issued in or after 1913 and continued until 15 November 1986 when finch trapping was banned byBarry Hodge, the environment minister. Trapping of certain finches ceased before 1986: the yellow-rumped mannikin after 15 November 1975 because of its scarcity; thezebra finch after 15 November 1981 because sufficient numbers were sourced from breeding stocks; and the Gouldian finch after 15 November 1981 because of its decline in numbers. Customs regulations in 1960 prohibited the export of live Australian fauna for commercial purposes and strict standards were applied to exports of specimens of native fauna for scientific research or zoological display. In 1971 Australia became a signatory to the Convention on International Trade in Endangered Species (CITES) and in 1976 Australia introduced the Customs (Endangered Species) Regulations to enforce import and export of species covered by CITES.[3]
