commonly feed in grassy areas such as farmland, grazing pastures, playing fields, golf courses and airfields where short grass makes foraging easy. They occasionally inhabit open forests and woodlands and are sometimes found in shrubby areas such as Australian heathland. Common starlings rarely inhabit dense, wet forests (i.e. rainforests or wet sclerophyll forests) but are found in coastal areas, where they nest and roost on cliffs and forage amongst seaweed. Their ability to adapt to a large variety of habitats has allowed them to disperse and establish themselves in diverse locations around the world resulting in a habitat range from coastal wetlands to alpine forests, from sea cliffs to mountain ranges above sea level. Introduced populations The common starling has been introduced to and has successfully established itself in New Zealand, Australia, South Africa, North America, Fiji and several Caribbean islands. As a result, it has also been able to migrate to Thailand, Southeast Asia and New Guinea. South America Five individuals conveyed on a ship from England alighted near Lago de Maracaibo in Venezuela in November 1949, but subsequently vanished. In 1987, a small population of common starlings was observed nesting in gardens in the city of Buenos Aires. Since then, despite some initial attempts at eradication, the bird has been expanding its breeding range at an average rate of per year, keeping within of the Atlantic coast. In Argentina, the species makes use of a variety of natural and man-made nesting sites, particularly woodpecker holes. Australia The common starling was introduced to Australia to consume insect pests of farm crops. Early settlers looked forward to their arrival, believing that common starlings were also important for the pollination of flax, a major agricultural product. Nest-boxes for the newly released birds were placed on farms and near crops. The common starling was introduced to Melbourne in 1857 and Sydney two decades later. By the 1880s, established populations were present in the southeast of the country thanks to the work of acclimatisation committees. By the 1920s, common starlings were widespread throughout Victoria, Queensland and New South Wales, but by then they were considered to be pests. Although common starlings were first sighted in Albany, Western Australia in 1917, they have been largely prevented from spreading to the state. The wide and arid Nullarbor Plain provides a natural barrier and control measures have been adopted that have killed 55,000 birds over three
